Interstate 75 south
The first of five interchanges in Collier County, Interstate 75 south approaches Collier County 846 (Immokalee Road) and Exit 111 in 1.25 miles. Photo taken 07/05/11.
Collier County 846, totaling 32.92 miles in length, begins at U.S. 41 west of Interstate 75 and travels east and northeast to end at Florida 29 in Immokalee. Delnor-Wiggins State Park lies along the gulf and is reached via CR 846 (Immokalee Road) and Bluebill Avenue. Corkscrew Swamp Sanctuary is also within reach of Exit 111 and is accessed via Collier County 846 east. Photo taken 07/05/11.
Interstate 75 south reaches Exit 111 and Collier County 846. Formally existing as part of a bypass for U.S. 41 through traffic in the Naples area, Immokalee Road has grown from a narrow two lane rural highway to a six-lane urban arterial, as farm land was replaced with commercial centers and subdivisions. Photo taken 07/05/11.
Interstate 75 expands with a forested median between Immokalee Road (CR 846) and Vanderbilt Beach Road. Photo taken 12/23/13.
Interstate 75 next encounters Pine Ridge Road (old Collier County 896) in four miles. The east coast cities of Fort Lauderdale and Miami make a first appearance for southbound travelers. Both cities lie along the Interstate 95 corridor. Photo taken 11/22/12.
The limited-access freeway approaches Pine Ridge Road, former CR 896, at Exit 107 in 1.25 miles. Photo taken 07/05/11.
At 7.0 miles, Collier County 896 extended west and east to connect U.S. 41 and Collier County 951, both of which parallel the interstate. Photo taken 07/05/11.
Known to the locals as Pine Ridge Road, former Collier County 896 acts as another major local east-west corridor in the Naples and North Naples area. Photo taken 11/22/12.
Newer subdivisions front the west side of Interstate 75 while a rural type street grid spreads to the east. Photo taken 11/22/12.
Collier County 886 (Golden Gate Parkway) intersects the interstate at Exit 105 in two miles, as it begins its eastward turn toward the east coast of Florida. Photo taken 07/05/11.
Golden Gate Parkway ventures west from Interstate 75 to U.S. 41 near the Coastland Center Mall. The east-west arterial shares a single point urban interchange (SPUI) with Airport-Pulling Road (former CR 31) half way between the interstate and U.S. highway. Photo taken 07/05/11.
Now within a half-mile of the interchange with Golden Gate Parkway (Exit 105), Interstate 75 reduces to a four-lane freeway at CR 886. Photo taken 07/05/11.
Not an original interchange during the initial construction of Interstate 75, Exit 105 was added to the system and opened to traffic on March 12, 2007. This interchange connects the interstate with nearby Golden Gate Estates (commonly known to locals as just Golden Gate) and also acts as a third access for Naples proper. Photo taken 07/05/11.
Dual lanes depart Interstate 75 south at Exit 105 for Collier County 886 (Golden Gate Parkway). County Road 886 overlays 4.96 miles of Golden Gate Parkway in two segments west from CR 951 (Collier Boulevard). Photo taken 11/22/12.
Collier County 886 travels east from I-75 two miles to Golden Gate. Westward Golden Gate Parkway provides connections with Naples Municipal Airport (APF) via Airport Pulling Road south and Naples Zoo via Goodlette Road. Photo taken 11/22/12.
Interstate 75 curves eastward on the initial approach to Everglades Parkway. The forested median gives a deceptive field, as subdivisions abut both sides of the freeway through to Exit 101. Photo taken 12/23/13.
Approaching the last interchange before Alligator Alley, motorists are advised to check their gas gauge as the next fueling facilities lie 50 miles ahead at Exit 49 (Snake Road). Photo taken 12/23/13.
Interstate 75 south begins its approach to Collier County 951 and Exit 101. This is the last exit before the toll plaza and the beginning of Alligator Alley. Photo taken 07/05/11.
Another advisory sign warns motorists about the lack of facilities and services along the tolled portion of interstate ahead. A variable message sign was added at this location in the late 2000's to also aid in travel times and for any possible delays due to traffic accidents or hurricane evacuations. Photo taken 07/05/11.
County Road 951 (Collier Boulevard) runs north-south through western Collier County, from Collier County 846 to the north to Interstate 75 at Exit 101 and again along a 2.61 stretch on Marco Island. A 7.07-mile state-maintained portion (Florida 951) exists between its intersection with U.S. 41 and the S.S. Judge Jolley Bridge near Marco Island. Motorists can also reach Florida 84 west from the upcoming diamond interchange. Photo taken 07/05/11.

Motorists prepare to depart for Collier County 951 (Collier Boulevard) at Exit 101. Prior to Interstate 75, Florida 84 continued east from its current terminus at Collier Boulevard across the everglades into Fort Lauderdale via the tolled Alligator Alley. The Alley was constructed in the 1960's as another way to link the southwest coast of Florida with the southeast coast. The original configuration was a narrow two-lane facility with daytime and nighttime speeds enforced. Alligator Alley was upgraded to interstate standards in the late 1980's and early 1990's, being the final segment of Interstate 75 to be completed in Florida. Once the interstate connected with the Alley on the west end, the original alignment of Florida 84 was severed.
Florida 84 currently ends at Collier County 951 and reemerges east of U.S. 27 (Exit 23) as frontage roads for both I-75 and I-595. A slip ramp in the median is also present at the northern end of this interchange to allow for contra-flow traffic during the event of an evacuation of the east coast. Photos taken 07/05/11.
Interstate 75 approaches the toll plaza entrance to Alligator Alley after Exit 101. Photo taken 12/23/13.
A dedicated lane is reserved for motorists with a Sunpass transponder. Alligator Alley is one of two Interstates in Florida where all lanes are tolled. The other is Interstate 275 over the Sunshine Skyway Bridge near St. Petersburg. Photo taken 12/23/13.
I-75 overtakes the original SR 84 (Beck Boulevard) routing just beyond the forthcoming toll plaza. Photo taken 12/23/13.
The 2-axle toll rate for vehicles to cross the Alley increased to $3.00 for cash transactions and $2.75 for Sunpass transponders on June 30, 2012. Additional pricing is applied for additional axles. Photo taken 12/23/13.
A small sign preceding the toll booths proclaims Interstate 75 as Alligator Alley, the popular name given to Everglades Parkway. Photo taken 06/25/05.

Open road tolling is not available for Interstate 75 travelers at the Everglades Parkway west toll gate. Instead and similar to the Sunshine Skyway plazas, motorists must slow down to 25 miles per hour through a converted toll booth lane. Photos taken 12/23/13.

Leaving the toll plaza, Interstate 75 south begins the long trek across the southern peninsula of Florida. The interstate encounters only two interchanges on its way to the Fort Lauderdale and Miami areas starting with SR 29 in 20 miles. Photos taken 12/23/13.
The first of many waterway crossings (Miller Canal) along Interstate 75 across the Everglades area. Photo taken 12/23/13.
The only overpass between Collier County 951 (Exit 101) and Florida 29 (Exit 80), Everglades Boulevard crosses Interstate 75 between mile marker 93 and 92. The north-south local road begins at Collier County 846 (Immokalee Road) 14.7 miles north of the interstate. There is currently no direct access between I-75 and Everglades Boulevard, but a study is in place to construct an interchange between the local road and interstate. Photo taken 12/23/13.

Interstate 75 prepares to encounter Florida 29 (Exit 80) after nearly a 21-mile exit-less stretch. Photo taken 12/28/06. Second photo taken 12/23/13.
Florida 29 ventures north and south from I-75 and Exit 80. Immokalee lies 20.4 miles north of the interstate in northeast Collier County. Heading south, Florida 29 makes its way to U.S. 41 and Everglades City, situated 17 miles and 21 miles (respectively) from the interstate. Photo taken 12/23/13.
SR 29 provides access to the vast areas of Florida Panther National Wildlife Refuge, Fakahatchee Strand Preserve State Park and Big Cypress National Preserve both north and south of Exit 80. CR 29 south from U.S. 41 extends the route to Everglades City, Chokoloskee, home of the historic Ted Smallwood Store, and western reaches of Everglades National Park. Photo taken 12/23/13.
I-75 reaches the diamond interchange with Florida 29 (Exit 80). The state highway continues north another 58.4 miles, passing through Immokalee and La Belle before ending at U.S. 27 south of Palmdale in Glades County. Florida 29 south ends at U.S. 41 (Tamiami Trail) 17 miles from the interstate. Photo taken 12/23/13.
Still within the confines of the Florida 29 diamond interchange, Interstate 75 enters the vast 729,000 acre Big Cypress National Preserve. Photo taken 12/23/13.

Travelers along Interstate 75 (Alligator Alley) are informed of the Everglades Radio Network via 98.7 on the FM dial. The radio network provides listeners opportunities to learn about history and other aspects about the Florida Everglades. Alternatively, 107.9 FM also offers the Everglades Radio Network. Photo taken 12/23/13.
Nearing the Broward County line, I-75 south leaves Big Cypress National Preserve. An succeeding pull-off area near mile marker 71 allows motorists an opportunity to view and photograph the surrounding area. Photo taken 12/23/13.
No facilities exist at the pull-off area but motorists can access a rest area complete with facilities in 7.3 miles. Photo taken 12/23/13.
Leaving the Big Cypress National Preserve Access Area along Interstate 75 south near Baxter Island. Photo taken 12/23/13.
Interstate 75 approaches the Collier County rest area at milepost 63. The facility resides on the south side of the toll road but is accessible from both directions.
An $8.8-million project resulted in the closure of the area between June 2013 and August 22, 2014 to expand the number of restrooms, add a new public safety center, and expand recreational access facilities for the Big Cypress National Preserve. Photo taken 12/28/06.
Motorists reach the departure ramp for the Collier County rest area facility. The facility affords travelers a chance to relax on the journey across the everglades. A recreation area with facilities exists 27.2 miles further east in Broward County. Photo taken 12/28/06.
