The Tampa Bay Area metropolitan area includes the cities of Tampa, St. Petersburg, and Clearwater. Tampa is the largest of the three cities, with nearly 350,000 residents and an area of 170 square miles. The city was originally incorporated in 1869. St. Petersburg, a city of 137 square miles, anchors southern Pinellas County with around 250,000 residents. It was incorporated in 1892. Clearwater, the Pinellas County seat, lies between the Gulf of Mexico and Old Tampa Bay along both U.S. 19 and State Road 60. The 39 square mile city is home to over 100,000 and was incorporated first in 1891.
Interstate 4 constitutes a major east-west freeway across the Florida peninsula along the U.S. 92 corridor. It begins at the Downtown Interchange with Interstate 275 in Tampa, then proceeds in an easterly direction toward Plant City, Lakeland, and Orlando. I-4 was both the first Interstate in Hillsborough County and statewide in Florida to be completed. Its origins in Tampa date back to 1941 as part of the Grand Central Expressway plan along what is now Kennedy Boulevard (SR 60). Planning maps displayed the current Interstate 4 in 1958, with staged construction following. The first portion completed was the stretch from U.S. 301 (Exit 7) to the Polk County line in 1960. The Downtown Interchange opened in 1964, with completion of the route in Hillsborough by 1965.1
Growth quickly accompanied the newly opened Interstate 4, and cities along it through Hillsborough, Orange and Polk Counties grew by 24% between 1964 and 1970. Traffic congestion ensued, and 100,000 vehicles per day were recorded along I-4 at 22nd Avenue (Exit 1) in 1970. Expansion for I-4 from I-275 east to Lakeland was planned for the period between 1987 and 1992. Construction however was delayed significantly in 1991 when the state reallocated funds for I-4 to expanding I-75 through North Florida instead.1
Within Hillsborough County, Interstate 4 was expanded to six overall lanes through various projects between September 1995 and December 2007. This included total reconstruction of the route in Tampa, with new carriageways built outside a wide grassy median. The median may be used for light rail in the future. Further east through Lakeland, widening was completed through Polk County in 2007.
Historically Interstate 4 extended west from Tampa along the Howard Frankland Bridge to north St. Petersburg in Pinellas County. This changed in 1971 when Interstate 75 was extended southward from the Downtown Interchange over I-4 through Pinellas County. I-75 would later shift to bypass Tampa to the east.
Interstate 75 provides the most direct route from the Tampa Bay region to Southwest Florida and Miami to the south and to Ocala, Interstate 10 near Lake City and points north to Atlanta and Michigan. The freeway stays east of Tampa, acting as a bypass of the metropolitan area while doubling as a commuter route for residents of Pasco County, New Tampa, Brandon, Riverview and Gibsonton.
The 1958 plan for Interstate 75 concluded the route in Tampa at what is now the Downtown Interchange between Interstates 4 and 275. This was the case because in 1961 all Interstate miles were already allocated for the state of Florida. The route of I-75 east of Tampa Bay was proposed as a separate bypass and was later incorporated into a freeway stretching to Naples in Southwest Florida. The toll road was tentatively named the West Coast Turnpike and planned for construction over a 15 year period. It included a western spur, the Palmetto Turnpike, to link it with the Sunshine Skyway. Not much was made public about the Western Turnpike, and by 1969 it was dropped in favor of extending Interstate 75 as additional interstate miles were made available to the state.2
Congress approved the route of Interstate 75 from Tampa to Miami in 1968, and the final design was unveiled in 1971. Extension of the route south to Miami involved renumbering I-4 west from Tampa to St. Petersburg as part of I-75. This took place formally in 1971, with I-75 ending at 38th Avenue North in St. Petersburg. Just two years later, I-75 was rerouted to bypass Tampa Bay, leaving the former route along the Howard Frankland Bridge as new I-275.3 Opposition from environmentalists and growing suburban communities rose as plans for construction of the new I-75 were finalized in 1972. Lawsuits from various environmental groups, and later homeowners, delayed work on the road, leading to a change in road design. This entailed angling I-75 further north in Hillsborough County and reducing the freeway from six to four lanes through the Hillsborough River area. The final route of I-75 was scheduled for completion in Hillsborough County by 1982.3
Construction of I-75 through the early 1980s focused on both ends of Hillsborough County, with work progressing to link the separate sections. I-75 was completed from I-275 at the Pasco County line south to SR 582 (Fowler Avenue) in 1984. Opening of the segment between SR 674 (Causeway Boulevard) and Fowler Avenue in 1985 completed the mainline in Hillsborough. Building of the Crosstown Expressway (SR 618) interchange followed in 1986.3
Widening of Interstate 75 to six or eight overall lanes through north Hillsborough kicked off on October 24, 2011 between Florida 582 (Exit 265) and Florida 56 (Exit 275). This work ran through spring 2016 and coincided with Pasco County expansion of I-75 between SR 56 and SR 54 (Exit 279) between March 2011 and June 2014. Additional work expanded I-75 northward between SR 54 and SR 52 (Exit 285) between May 2014 and winter 2018.
Interstate 175 – South Bay Drive
Interstate 175 is a short spur route leading east from Interstate 275 to Tropicana Field (home of the Tampa Bay Rays MLB team) and the south side of Downtown St. Petersburg. One of the shortest Interstate highways in the national system, it runs partially below grade and ends at Florida 687 (4th Street South).
I-175 was planned along side I-375 as ‘downtown feeders’ to St. Petersburg in the mid-1960s as state roads. Construction on both routes followed in the late 1970s, but I-175 was delayed due to the high cost of land acquisition and lawsuits filed in an attempt to halt work. The $5.5-million freeway was the most expensive road per mile to ever be constructed in Florida at the time when it opened on April 23, 1980.5
The 1.44-mile route was incorporated into the Interstate system in 1978 when Florida realized that the state budget would not support completion of it’s portion of the Interstate system by 1986, when federal funding was scheduled to run out. The state canceled part of I-75 through Hillsborough County to offset the deficit, leaving five federally funded intestate miles to allocate elsewhere. These were used for both Interstates 175 and 375.
Interstate 275 forms a 60-mile loop west from Interstate 75 through the urban cores of both Tampa and St. Petersburg. A busy route, the freeway winds northward from the Sunshine Skyway through southern Pinellas to the Howard Frankland Bridge across Old Tampa Bay. The freeway turns east toward Downtown Tampa and north along a congested corridor from near Ybor City to North Tampa and Lutz.
Interstate 275 was commissioned in 1973 over the former path of Interstate 75 through both Tampa and St. Petersburg. Construction of I-275 through Tampa initially focused on the stretch between Downtown Tampa and the Howard Franklin Bridge between 1960 and 1964 and from Pasco County southward to Bearss Avenue, which opened in 1961. The east-west portion of the route was designated as Interstate 4 with four overall lanes and an eight foot grassy median.6
Construction of the Downtown Interchange, where I-4 and I-275 currently meet, was completed in 1965. This preceded work to open I-75 southward from Bearss Avenue in 1966. The vigorously opposed stretch of I-75 between Sligh and Floribraska Avenue was completed in December 1967.6
Further south, Interstate 275 spans Old Tampa Bay across the three-mile long Howard Frankland Bridge. The bridge first opened in August 1960 with a single span dumping traffic onto 4th Street North at its west end. Completion of I-75 south into Pinellas aided in the transformation of 4th Street into a busy commercial route. Ensuing commercial interests established along the route delayed construction of I-275 until 1969, when work commenced on an extension south to Roosevelt Boulevard (SR 686) and 58th Avenue North. Subsequent construction extended the freeway south to I-375 in 1978, and I-175 by April of 1980.7
South from Downtown St. Petersburg, construction on I-275 commenced in June 1978. Resistance to the new freeway was less than previously encountered in areas to the north, but opposition from both environmentalists and Eckerd College resulted in some hurdles. Agreed compromises between parties involved were incorporated into the freeway design including landscaping, the installation of sound walls, the rebuilding of a popular marina displaced by the route and the redesign of the Pinellas Bayway/54th Avenue S interchange to reduce to impact to Eckerd College land. Work took I-275 southward to a temporary end point six times from 1978 to 1984. The portion south to 28th Street South opened in January 1981, to 22nd Avenue South in May 1982, and to 54th Avenue South in January 1984.8 The route through to the famed Sunshine Skyway Bridge was opened by June 1985. The cable-stayed bridge was completed in 1987, replacing a cantilever bridge by the same name that partially collapsed in 1980. The four-lane toll bridge totals 4.2 miles over the main shipping channel for both Port Tampa Bay and Port Manatee.
As traffic counts increased, capacity improvement projects were made to Interstate 275 in both Hillsborough and Pinellas Counties. Reconstruction of the freeway took place in Tampa through the 1970s, with expansion to six overall lanes and redesign of the diamond interchange at Memorial Highway (SR 60) into a parclo between 1974-76. The Himes Avenue interchange was first proposed in May 1983 and advertised to enhance access to Tampa Stadium for the 1984 Superbowl. The partial interchange was to be funded by the Tampa Bay Bucs franchise and Westshore mogal Al Austin, who owned a large tract of land near the stadium location. Funding did not acrue in time for the Superbowl, and the interchange was built in late 1984 and paid mostly by the state.6
The Gandy Boulevard interchange with SR 694 was partially completed in 1976. Plans at that time called for Gandy to be built as a full freeway, so elements of the junction with I-275 were tabled until that upgrade came to pass. The cancellation of the Gandy Freeway led to an upgrade at the interchange with I-275 to provide the previously missing movements.7 A second span for the Howard Franklin Bridge across Old Tampa Bay opened in August 1991. The bridge did double duty while crews rehabilitated the 1960 span, ultimately leading to eight overall lanes of capacity.
Modernization of the freeway through both Tampa and St. Petersburg commenced in November 1999 and continues through fall 2016. This includes the total rebuilding of I-275 between the Howard Frankland Bridge and Downtown Interchange with new carriageways and a wide grassy median reserved for potential light rail. Work included the acquisition of several blocks worth of property to the south of I-275 to accommodate the wider footprint.
Interstate 375 – North Bay Drive
Interstate 375 forms a second short spur route leading from Interstate 275 into Downtown St. Petersburg. The 1.34-mile route runs east, partially along a viaduct, to the couplet of 4th and 5th Avenues North (Florida 595) near Mirror Lake and just shy of the western terminus of U.S. 92 (4th Street North).
Planned along with I-175 to the south, Interstate 375 cost $3.1-million to build and opened initially from I-275 east to 9th Street North on January 17, 1978. Completion of the route eastward followed in January 1979.5
U.S. 19 follows the Gulf Coast southward from the Nature Coast through to New Port Richey and built-up areas of west Pasco County. Leading south through Pinellas County, the highway splits with an Alternate route looping west through Palm Harbor, Dunedin, Downtown Clearwater and Seminole while the mainline stays east to Pinellas Park and St. Petersburg. U.S. 19 is heavily congested throughout Pinellas as it provides the main commuter route throughout the urban county. 12.3 miles of the US highway, from Pinellas Park to north Clearwater, run along a limited access freeway.
Leading south from Clearwater, U.S. 19 Alternate expands into an arterial style road though Largo and Seminole to reconvene with U.S. 19 (34th Street North) via 5th Avenue North in St. Petersburg. U.S. 19 follows 34th Street south from Pinellas Park to combine with Interstate 275 ahead of the Sunshine Skyway Bridge while Florida 595 provides a direct connection into Downtown St. Petersburg as the former southern extent of U.S. 19.
The overlap between I-275 and U.S. 19 across Tampa Bay is one of three cases in Florida where a U.S. route merges onto an Interstate highway (U.S. 17 on I-10 and I-95 in Jacksonville and U.S. 1 in Miami being the others). The toll bridge turns the paired routes east at Terra Ceia, where U.S. 19 branches southward via a wye interchange for Palmetto. Once in Memphis, north of Palmetto and Bradenton, U.S. 19 ends at its junction with U.S. 41.
U.S. 19 was laid out in 1929 by the fderal government through Pinellas County and remained roughly unchanged until the early 1950s. Then a new inland route was constructed, with the former along the coast redesigned as U.S. 19 Alternate. Population growth quickly overran the newer alignment for U.S. 19, resulting in 1962 plans for a parallel freeway along Belcher Road. That route was not funded in time, and a subsequent north-south toll road plan for the U.S. 19 corridor was killed by voters in 1976. All other planned freeways in Pinellas not already under construction at the time were cancelled by the early 1980s.9
Increasing traffic congestion in the mid-1980s led to plan in 1987 to upgrade U.S. 19 to an urban freeway with six overall lanes and a companion frontage road system from Gandy Boulevard (SR 694) north to the Pasco County line. Funding prioritzed the building of ovepasses and frontage roads at the busiest intersections first, with lower costs upgrades following. Work to add an overpass at Roosevelt Boulevard (SR 686) ran between Janary 1987 and March 1989. A second set of bridges opened in December 1989 to carry U.S. 19 over Ulmerton Road (SR 688).9
Further construction upgraded U.S. 19 to a freeway on the stretch between Main Street (SR 580) and Countryside Boulevard in Clearwater with work undertaken from 1992 to May 1994. Moving forward, funding issues again arose and pushed U.S. 19 upgrades back into the mid-2000s with completion of work between Pinellas Park and Dunedin. With all but two segments converted to limited access standards by 2009, the two remaining portions: Whitney Road to Florida 60 and Sunset Point Road to Countryside Boulevard in Clearwater were completed in summer 2015. Future work to extend the freeway north to County Road 95 near Palm Harbor, including a new interchange with Curlew Road (Florida 586), will take place when funding becomes available. Upgrades on the remaining stretch north to Pasco County are not planned at this time.
U.S. 41 – Tamiami Trail
U.S. 41 is the Tamiami Trail, so named for its connection between Tampa and Miami. In the Tampa Bay area, U.S. 41 stays east of Tampa Bay, paralleling I-75 to the west. Through the city of Tampa, the route partitions with a Business loop through Downtown and the mainline taking a surface bypass partially with U.S. 92 along Hillsborough Avenue. The pair merge ahead of Lutz with U.S. 41 continuing to suburban areas of Land O’ Lakes in Pasco County.
U.S. 41 exists as a suburban commuter route, urban arterial and industrial highway throughout its course through the Tampa Bay area. U.S. 41 Business provides the main route to Port Tampa Bay while U.S. 41 south from Tampa serves the growing areas of Apollo Beach, Ruskin and Sun City Center. As such all of U.S. 41 south from Tampa to Bradenton carries at least four lanes.
Historically the Business route for U.S. 41 represents the original northern extent of the intrastate alignment of U.S. 541. U.S. 541 follows the current alignment of U.S. 301 south from Tampa to Palmetto. It was decommissioned in 1951.
Gandy Blvd / Dale Mabry Hwy / Hillsbourgh Av
U.S. 92 through Tampa Bay consists of either a local roadway or commuter route, having been supplanted by Interstate 4 and the Crosstown Expressway (Florida 618). The US route originates at the intersection of 4th Street North and 5th Avenue North outside Downtown Petersburg. The seemingly arbitrary end point results from this location representing the historic south end of U.S. 19.
Traveling 4th Street North, U.S. 92 lines a business strip northward to Gandy Boulevard in North St. Petersburg. Gandy Boulevard, a wide boulevard with original plans as a freeway, travels east from Pinellas Park as Florida 694 to become the U.S. 92 mainline east of 4th Street North. U.S. 92 lines the four-lane highway through to the Gandy Bridge across Tampa Bay.
Once in South Tampa, U.S. 92 transitions into a commercial arterial, taking Gandy Boulevard to both the west end of the Leroy Selmon Expressway (SR 618) and Dale Mabry Highway (SR 573). Dale Mabry Highway takes U.S. 92 due north along an equally commercialized stretch bisecting the Tampa peninsula through to I-275 and Raymond James Stadium (home of the Tampa Bay Buccaneers NFL team). Dale Mabry Highway expands to six lanes along this stretch and almost is never referenced to by any of its numbered components (SR 573, U.S. 92, SR 580 and SR 597).
A six-ramp partial cloverleaf interchange sees U.S. 92 depart Dale Mabry Highway for Hillsborough Avenue (SR 580 to the west) east to Seminole Heights. U.S. 41 ties into the arterial between Nebraska Avenue and 40th Street as well. Hillsborough Avenue otherwise carries U.S. 92 east away from Tampa, with a brief split at U.S. 301 and I-4, where the route utilizes collector distributor roadways of the freeway.
Beyond the I-4 and U.S. 301 confluence at the Florida State Fairgrounds, U.S. 92 downgrades into a two-lane route as it parallels Interstate 4 east to Plant City. Through Downtown Plant City, the route partitions into a one-way couplet. U.S. 92 exits Hillsborough County en route to Downtown Lakeland to the south of I-4.
U.S. 301 mirrors the course of U.S. 41 to the east of Tampa Bay between Palmetto and Tampa. The route begins at U.S. 41 near Downtown Sarasota, traveling a four to six lane route northward to Bradenton and a short overlap with U.S. 41 across the Manatee River into Palmetto.
Once in Palmetto, U.S. 301 splits with U.S. 41 for an eastern push to Ellenton and Parrish in northern Manatee County. The route reduces to a two-lane rural highway along this stretch, but suburban expansion from Sun City Center and Riverview resulted in widening to four and six lanes northward into Hillsborough County. As such, U.S. 301 generally serves as a commuter or local route through to the Brandon area.
Having stayed east of I-75 since Ellenton, U.S. 301 loops west through a large industrial park area between the Crosstown Expressway and Florida State Fairgrounds at Interstate 4. Curving back to the east, the US highway passes under I-75 with no direct access en route to Thonotosassa and Zephyrhills in Pasco County.
Overall U.S. 301 connects the northeast with the Deep South. The nearly 1,100 mile route provides part of the through route between Tampa Bay and Jacksonville, supplementing the lack of freeway between Ocala and Baldwin. U.S. 301 generally mirrors I-95 northward to Glasgow, Delaware.
A number of state roads serve Pinellas County to the west, such as SR 584, SR 586, SR 590, SR 595, SR 666, SR 679, SR 682, SR 686, SR 687, SR 688, SR 693, SR 694 and SR 699. Unsigned state roads completely mirroring Interstates and U.S. routes include SR 41, SR 43, SR 55, SR 93, SR 93A, SR 400, SR 599 and SR 600. See the Pinellas County guide for information on state roads there.
Florida 45 is the hidden route for U.S. 41 between U.S. 92 / Florida 600 in Tampa and U.S. 27 at High Springs. A 3.17-mile section of the state road travels solo along Nebraska Avenue from Hillsborough Avenue south to the one-way couplet of U.S. 41 Business & Florida 60 along Jackson Street and Kennedy Boulevard in Downtown Tampa.
Courtney Campbell Causeway / Memorial Hwy / Kennedy Blvd / Adamo Dr / Brandon Blvd
Florida 60, in keeping with tradition for most two-digit Florida state roads, is a major cross-peninsula route between Tampa Bay and Vero Beach on the Atlantic Ocean. It starts in Clearwater Beach and crosses Clearwater Harbor east on fixed high-level span opened in August 2005. A one-way couplet partitions the route along Chestnut and Court Streets through Downtown Clearwater, leading to an arterial style route (Gulf to Bay Boulevard) east to Courtney Campbell Causeway across Old Tampa Bay.
Once east of Rocky Point, Florida 60 transitions into a limited access route, utilizing a portion of Memorial Highway by Tampa International Airport (TPA) to Interstate 275 and Kennedy Boulevard at Westshore Mall. Kennedy Boulevard carries the state road east along an business strip to the University of Tampa and the Tampa central business district. Once in Downtown Tampa, SR 60 splits again into a couplet along Jackson Street east and Kennedy Boulevard west. This portion ties the route with U.S. 41 Business as the pair angle north and than east around YBor Channel by Port Tampa Bay.
Adamo Drive doubles as State Road 60 east from Channelside Drive, serving industrial areas north of the port and along side the Crosstown Expressway. Further east, Florida 60 (Brandon Boulevard) provides the main east-west route through unincorporated Brandon, a sprawling community east of Interstate 75. SR 60 remains with at least four overall lanes through rural east Hillsborough, exiting the county for Mulberry and Bartow in Polk County.
Until 1998, the original Veterans Expressway (Florida 589 Toll) alignment veered east at Van Dyke Road (CR 685A) to end at Dale Mabry Highway (SR 597) near Lutz. SR 589 extended northward in 2001 to Pasco and Hernando Counties along the new Suncoast Parkway. This left the 3.04-mile spur to Dale Mabry Highway as new State Road 568.
Stubs at the east end of Florida 568 allude to former plans to extend the toll road east onto the cancelled Lutz Expressway to Interstate 275. There are no exits otherwise along the east-west route.
North 39th and 40th Streets
Florida 569 leads north from Florida 60 (Adamo Drive) along 39th Street and passes below Interstate 4 along 40th Street to end at U.S. 41 (Melburne Boulevard) in Tampa. The state road used to have a diamond interchange with Interstate 4 (Exit 2), but that was removed with the freeway expansion project of 2005-07. A second diamond interchange at the south end of SR 569 with the Crosstown Expressway was also removed to accommodate flyover ramps with the January 2014-opened Selmon Connector between SR 618 and I-4.
Dale Mabry Highway
Florida 573 runs along the southernmost 1.90 mile extent of Dale Mabry Highway between U.S. 92 (Gandy Boulevard) and the main gate to MacDill Air Force Base. The short state road includes a roundabout with Marcum Street just north of the AFB boundary.
Dr. Martin Luther King, Jr. Boulevard
Florida 574 overlays all of Dr. Martin Luther King, Jr. Boulevard from U.S. 92 (Dale Mabry Highway) in Tampa to Mango, Seffner and Dover. The state road follows Reynolds Street to end at U.S. 92 in Plant City. The majority of the route between Raymond James Stadium and Mango accommodates four lanes of traffic.
Just a 0.499-mile stretch of Fletcher Avenue, between U.S. 41 Business (Florida Avenue) and U.S. 41 (Nebraska Avenue), comprises the entirely of State Road 579. This segment runs through the diamond interchange with Interstate 275. Fletcher Avenue east from SR 579 carries CR 582A to I-75 at CR 579. West of Florida Avenue, the route is either unsigned CR 582A or not a county road.
Main St / Hillsborough Av / Dale Mabry Hwy / Busch Blvd
Florida 580 runs east from Dunedin in Pinellas County to Temple Terrace in Hillsborough County. The westernmost 0.48 miles follows Skinner Boulevard, a 1989 realignment bypassing Main Street and Downtown Dunedin to the north. Main Street carries the remainder of SR 580 east to northern reaches of Clearwater.
Florida 580 overtook the former bridge of Florida 590 across Safety Harbor, truncating the route east through Oldsmar to Tampa Road (SR 584). This included a 1997-opened four-lane alignment to the north. SR 580 along Tampa Road becomes Hillsborough Avenue across the county line. The six-lane arterial provides the first land-based route between Pinellas and Hillsborough County north of Courtney Campbell Causeway.
Hillsborough Avenue angles southeast through the Town ‘N Country community through to the Veterans Expressway and north side of Tampa International Airport (TPA). SR 580 constitutes a busy commuter route along this stretch.
Further east, SR 580 turns north to overtake Dale Mabry Highway from the departing U.S. 92. The northward leg takes the route to Busch Boulevard east across Carrollwood to north Tampa, Busch Gardens and Florida 583 (56th Street) in Temple Terrace.
30th Street / Bruce B. Downs Boulevard
Bruce B. Downs Boulevard (County Road 581) is a major route leading north from SR 582 (Fowler Avenue) and the University of South Florida (USF) to New Tampa and Wesley Chapel in Pasco County. CR 581 follows the arterial northward to SR 56, where it transitions to SR 581 for the remainder of the drive north to SR 54. County Road 581 is well signed in Pasco County and sporadically posted in Hillsborough County. The southernmost 1.5 miles of CR 581 follows 30th Street to Busch Gardens and SR 580 as an unsigned route.
As part of the busy commuter route for residents of New Tampa, a high speed flyover opened from Bruce B. Downs Boulevard (CR 581) south to Interstate 75 south on July 24, 2008. The ramp cost $42 million and opened eight months ahead of schedule.1
State Road 582 lines Fowler Avenue for 7.83 miles between U.S. 41 Business (Florida Avenue) in Tampa and U.S. 301 east of Temple Terrace. The entire route consists of four to six lane arterial, with commercialized stretches by University Mall and within the University of South Florida campus vicinity.
North 50 and 56th Streets / Lake Avenue
Florida 583 stems north from the U.S. 41 (North 50th Street) turn onto Melbourne Boulevard west in east Tampa. The state road lines 50th Street north by Grant Park to SR 574, where it angles beyond the Tampa city limits northeast to 56th Street. 56th Street carries the state road north into Temple Terrace, where Florida 583 ends at Florida 582 (Fowler Avenue), opposite unsigned CR 583.
North 21st and 22nd Streets
SR 585 formerly stemmed north 3.08 miles from U.S. 41 Business and SR 60 (Adamo Drive) along 21st & 22nd Streets through YBor City before combining into just 22nd Street through to Hillsborough Avenue (U.S. 41 & 92). Completion of the Crosstown Connector on January 6, 2014 replaced SR 585 as the truck route between Port Tampa Bay and Interstate 4. Subsequent work funded by FDOT resurfaced and made stormwater sewer upgrades along the 21st and 22nd Street alignment before roadway maintenance was turned over to the city of Tampa in 2017.
An unsigned County Road 585 existed along Rowlett Park Drive north from Sligh Avenue as well. This stretch was removed from the system by 2010.
Veterans Expressway / Suncoast Parkway
The Veterans Expressway portion of Florida 589 winds northward from Memorial Highway and Florida 60 to the Northdale area in northern Hillsborough County. The toll road was completed in September 1994 as a commuter route to alleviate Dale Mabry Highway.
Construction for the northward extension of Florida 589 wrapped up in 2001, when the Suncoast Parkway was completed between Northdale and U.S. 98 in Hernando County. The lengthened toll road serves suburban areas of Pasco County while providing a fast route between Tampa Bay and the Nature Coast.
$380 million in road work underway along the Veterans Expressway widened the southernmost 11 miles of SR 589. Included in the work was the elimination of cash-collection toll booths and the June 14, 2014 switch to all-electronic tolling. Work on the six and eight-lane expansion runs through early 2018.
Dale Mabry Highway
Florida 597 lines the northernmost 10.64 miles of Dale Mabry Highway, from the folded-diamond interchange with SR 580 (Hillsborough Avenue) east and CR 587 (Gunn Highway) north to U.S. 41 (Land O’ Lakes Boulevard) in Pasco County. Dale Mabry Highway north to Northdale consists of commercial arterial, with less development and some rural stretches lining the route northward to County Line Road.
Spruce Street / Boy Scout Boulevard
Florida 616 follows a combination of Spruce Street, Boy Scout Boulevard, and Columbus Drive east from Florida 60 (Memorial Highway) and Tampa International Airport (TPA) 1.79 miles to U.S. 92 (Dale Mabry Highway) in Tampa. The four to six-lane arterial replaced Florida 589 when the Veterans Expressway was designated that number.
Lee Roy Selmon Expressway
Florida 618 is the tolled LeRoy Selmon Expressway, taking an east-west path across Tampa to Brandon. Mostly an elevated highway, the route is the fastest way from Gandy Boulevard (U.S. 92) and South Tampa northeast to Downtown Tampa. The route east to Brandon comprises an important commuter route to the uninicorporated suburb of Brandon. Named the Crosstown Expressway until 2008, it was completed in 1986.
The toll road includes a reversible roadway linking Channelside in Downtown Tampa with Brandon Parkway and Lakewood Drive in Brandon. Designated hidden State Road 618A, the two to three lane roadway flows inbound in the morning and outbound during the evening. It opened to traffic by August 2006.
College Avenue / Sun City Center Boulevard
SR 674 stretches 25.51 miles east from U.S. 41 in Ruskin to SR 37 in southwest Polk County. The state road bisects the Sun City Center community east from Interstate 75 as a multi-lane arterial.
East of U.S. 301, SR 674 travels through the unincorporated town of Wimauma. Beyond there, SR 674 provides a truck route east to a number of phosphate mines through to Fort Lonesome and SR 37.

Like SR 579 to the south, State Road 678 consists of a short alignment between U.S. 41 Business (Florida Avenue) and U.S. 41 (Nebraska Avenue) north of Tampa. The 0.501-mile state road lines Bearss Avenue through its diamond interchange with Interstate 275. Bearss Avenue leads west to Lake Magdalene, partially as unsigned CR 582, and east to CR 581 (Bruce B. Downs Boulevard) as an local arterial.
Mostly an unsigned route, State Road 685 travels north 14.63 miles from Tampa to Lutz. A 0.98-mile segment follows Henderson Boulevard as a signed route between U.S. 92 (Dale Mabry Highway) and Florida 60 (Kennedy Boulevard). The remainder of the route is unsigned as it overlays SR 60 east to Downtown Tampa to become the state road counterpart of U.S. 41 Business north to U.S. 41 at Lutz.
