The Big Easy, New Orleans is the hub of the upper Gulf of Mexico coastline, with around 400,000 residents. The busy port city lines the banks of the mighty Mississippi south of Lake Pontchartrain and 113 miles northwest from the river delta. Founded in 1718 by French colonialists, the city centered around Jackson Square (originally named Place d’Armes) and consisted of just the Vieux Carre. Spanish rule of Louisiana followed between 1762 and 1801, before the territory was ceded back to France for a two year period. The Louisiana Purchase was sold to the United States in 1803, and the cultural dynamic of New Orleans changed with an influx of Americans and European immigrants. As the population increased, tensions rose between the newly arrived Americans and Europeans, who settled west of Canal Street in the “American Sector” (today’s Central Business District), with the established European Creoles in the French Quarter. Conflicts were a regular issue, and the Canal Street median became a neutral area where the two sides would meet to conduct business without imposing upon the opposite territory. This led to the New Orleans term “neutral ground”, used to describe city medians.

New Orleans grew to the fourth largest city in the United States by the mid-1800s. Today the city is best known for Mardi Gras, the home of Jazz, and occasionally the Super Bowl. The cultural hearth of the city is unmatched by any other in the southeast states and perhaps the whole country.

The history of New Orleans changed forever when the city was dealt a major blow by the landfall of Hurricane Katrina on August 29, 2005. The catastrophic storm raked the city with 115 mile per hour winds and a storm surge that toppled several sections of the protective levee system. During Labor Day weekend of 2005, some of the levees failed, allowing water from Lake Ponchartrain to inundate the city. The following weeks resulted in a full scale evacuation of New Orleans as 10 to 15 feet of water submerged portions of the city. Recovery efforts continued in the long term, but some nine months after the landfall of Katrina, the city remained a shell of its former self. It was estimated that just 225,000 lived in the city as of mid 2006, compared to 496,938 recorded in the 2000 census. Those numbers were expected to climb slowly as rebuilding continued, and by the 2010 census the population rebounded to 343,829. A number of roads and bridges were effected by the storm, leading to eventual upgrades or infrastructure improvements. See the Hurricane Katrina Road Information page for a summary of impacts on numbered highways during and after the storm.


Interstate 10


Interstate 10

An often congested freeway serving most of metro New Orleans. The freeway enters the area from the west along a ten mile viaduct the Bonnet Carre Floodway along the southwestern periphery of Lake Ponchartrain. An elevated semi-directional T interchange joins Interstate 10 with I-310, a spur southwest to Boutte ahead of the viaduct end at Kenner. The freeway proceeds east at-grade with six to eight lanes and heavy traffic by Louis Armstrong New Orleans International Airport (MSY) to unincorporated suburbs of Jefferson Parish and Metairie.

East across the Metairie Outfall Canal, I-10 enters Orleans Parish and the city of New Orleans, where it splits with Interstate 610 at an interchange rebuilt by early 2000. I-610 provides a cutoff across City Park to bypass Downtown while Interstate 10 angles southeast along the Pontchartrain Expressway to the Superdome. There it shifts northeast over Claiborne Avenue to the Seventh Ward. The Pontchartrain Expressway was constructed during the late 1950s while the elevated Claiborne expressway was built in the 1960s. The exchange linking the two freeways with the Pontchartrain Expressway southeast to the Greater New Orleans Bridge was improved in 1993/94.

Interstates 10 and 610 reconvene between the Gentilly Terrace and St. Roch neighborhoods at a wye interchange. I-10 proceeds east from there across the High Rise Bridge over the Industrial Canal to New Orleans East, an area hard hit by Hurricane Katrina. The freeway returns to grade level and shifts north and east along a commercial corridor lined with service roads through to Interstate 510. The remainder of the route traverses wetland areas through Bayou Sauvage National Wildlife Refuge to Point aux Herbes and the 5.6 mile long twin bridges across Lake Pontchartrain.

Interstate 310


Interstate 310

Freeway serving the southwest portion of the New Orleans metropolitan area. Interstate 310 angles southwest from I-10 along a 5.8 mile long viaduct system across swampland in eastern St. Charles Parish. Southward ahead of Destrehan, I-310 lowers to grade level briefly before rising onto the Hale Boggs Bridge across the Mississippi River. The cable-stayed bridge, which saw deck replacement in 1999/2000, joins Destrehan and LA 48 with Luling and Louisiana 18.

Interstate 310 runs along agricultural and suburban areas from Luling to a three-wye interchange with LA 3127. Turning southeast across wetland areas, I-310 concludes at a partially built interchange with U.S. 90 by the community of Boutte. Stubs built into the exchange will extend the route to Interstate 49 South, or become a part of I-49 should the eastern most extent be dropped.

Interstate 510


Interstate 510

Interstate 510 links Chalmette with Interstate 10 at New Orleans East in conjunction with LA 47. The 3.16 mile freeway spur replaced Paris Road (old LA 47) southward from Little Woods to the Intracoastal Waterway Bridge by 1992. LA 47 extends south from the steel through arch bridge to end at LA 46 in the St. Bernards Parish seat of Chalmette.

I-510 serves the NASA Michoud Assembly Facility and industrial areas within the Viavant – Venetian Isles area south of U.S. 90 (Chef Menteur Highway). The abandoned Six Flags New Orleans theme park is located southeast of the exchange joining I-10/510 as well. Traffic counts along I-510/LA 47 ranged from 28,241 to 28,501 vehicles per day (vpd) as recorded by LADOTD in 2013.

Interstate 610


Interstate 610

Traveling 4.3 miles, Interstate 610 allows through traffic to bypass the Interstate 10 legs south to the New Orleans Central Business District and French Quarter. The freeway concludes at wye interchanges with I-10 at both ends, is mostly elevated on viaduct, and crosses New Orleans City Park. Completed in stages between 1964 and 1975, the busy route topped out with 94,470 vpd in 2013.

Interstate 910


Pontchartrain / Westbank Expressways

Interstate 910 is the unsigned designation for U.S. 90 Business along both the Pontchartrain and West Bank Expressways. With the long term plan to extend Interstate 49 southeast from Lafayette to New Orleans, LADOTD officials sought to redesignate U.S. 90 Business as Interstate 49 in 1999 in an effort to boost business development on the West Bank. The request was rejected, with FHWA officials instead designating the freeway as Interstate 910 as the 9.7 mile route met federal interstate standards.1 The route was never signed, but it was inventoried in the Interstate Route Log and Finders List starting with the October 31, 2002 edition.

Other Freeways


Lake Pontchartrain Causeway

Concrete bridge system bisecting Lake Pontchartrain between Metairie and Mandeville on the North Shore. The first two lane bridge opened in 1956 with two-way traffic. A twin span was added by 1969, bringing the 24 mile long route to four overall lanes.2 Separated by 80 feet, seven crossovers connect the two spans. Double leaf bascules located eight miles south of the North Shore allow the passage of tall ships. Openings are not conducted during the morning or evening peak hours during weekdays.

Speed limits on the twin bridges were increased from 55 to 65 miles per hour overall in 2007, with the exceptions of at the navigation humps. Coupled with the addition of enhanced lighting and electronic speed advisory signs, the speed limit increase cost $2.8 million. Prior to the change, the northbound span was increased to 65 mph in 2004 while the southbound span remained at 55 mph during night time hours.3

Tolls are collected for southbound drivers at a five-booth plaza in Mandeville. The northbound plaza ceased operations in May 1999 to improve traffic flow at Metairie, as tolls doubled for the Causeway southbound. For a period of time, the inactive toll booths sat unused with drivers passing through the facility at 25 miles per hour. The 1956 canopy at the Metairie toll plaza was eventually dismantled on the morning of January 29, 2011. The work was incorporated in a $43.2 million Corps of Engineers flood control project that raised a section of Causeway Boulevard and constructed a new flood wall.4

Causeway Boulevard joins the north end of Lake Pontchartrain Causeway with U.S. 190 west directly. Additionally approach roads provide access to Louisiana 22 west to Madisonville and U.S. 190 east to Mandeville. U.S. 190 provides a direct connection to Interstate 12 and Covington via a freeway.

Causeway Boulevard originates to the south at River Road in Jefferson. Louisiana 3046 lines the route north from ramps with U.S. 90 (Jefferson Highway) to a circle interchange with U.S. 61 (Airline Drive). North of there, the boulevard transitions into a busy commercial arterial through Metairie and the Causeway south end. The cloverleaf interchange with Interstate 10 was upgraded between 2009 and 2012 to add flyovers and eliminate weaving traffic patterns. Traffic counts north of the exchange top out above 100,000 vpd.

Older road maps show Causeway Boulevard as the Greater New Orleans Expressway. An early signing system directed motorists to the south end of Lake Pontchartrain Causeway with a color code system of markers. The system used red markers for traffic into New Orleans and points east. Green markers led drivers to U.S. 90 and points west, while blue markers directed traffic to Baton Rouge and connections along U.S. 61.

Earhart Expressway / Riverfront Expressway

Starting at the foot of the Greater New Orleans Bridge (U.S. 90 Business), the Riverfront or Vieux Carre Expressway was proposed to follow the Mississippi River banks northeast through the Central Business District as an elevated freeway in front of Jackson Square through the French Quarter. The proposed route then turned northward at Elysian Fields Avenue and followed its median (similar to I-10 above Claiborne Avenue) to a junction with Interstate 10. The Riverfront Expressway is one reason why the interchange between Interstate 10 and Elysian Fields Avenue is so wide today.6

Origins of the unconstructed Vieux Carre Expressway date back to 1946 when New York transportation pioneer Robert Moses unveiled his “Arterial Plan for New Orleans.” The expressway was the most controversial element of the Moses plan. However criticism of the idea did not emerge until October 1964 when $25 million in funds were allocated for the 3.5 mile freeway project. Already under construction at the time was a 690 foot long, 98 foot wide six-lane tunnel. The subterranean roadwork began between Poydras and Canal Streets at the foundations of the 1967 opened Rivergate.7 The tunnel was eventually completed and later incorporated as a valet parking garage for Harrah’s casino.6 A heated battle ensued from there between proponents of the Riverfront Expressway and community leaders. Opposition finally won out July of 1969.7

The Riverfront Expressway would have also continued northwest from the Pontchartrain Expressway (U.S. 90 Business) and the Lower Garden District to a proposed Mississippi River bridge uptown and an extension of the Earhart Expressway east from Jefferson Parish. This section was not proposed as part of Interstate 310.6

A study in 1969 attempted to reinforce the concept of an outer belt freeway system between the Riverfront and Earhart Expressways. The plan also envisioned a new Mississippi River crossing uptown via Earhart Boulevard at Napoleon Avenue.7 The Earhart Expressway was to travel from LA 49 (Williams Boulevard), near New Orleans International Airport (MSY), eastward to the Pontchartrain Expressway via Earhart Boulevard. Following the cancellation of the Riverfront Expressway proposal, the Earhart Expressway was rescinded westward to the New Orleans and Jefferson Parish line.

The portion of the Earhart Expressway within Jefferson Parish was constructed. However, some elements were left unbuilt, such as an interchange with Causeway Boulevard and an eastbound off-ramp to U.S. 61 (Airline Drive) near the New Orleans city line. The northern terminus also alludes to further extension, with stub ends and a wide right of way at LA 3154 (Dickory Drive). LA 3139 south transitions to Earhart Boulevard, a four lane boulevard to Downtown New Orleans. The state route ends at the intersection with Monroe Street.

LA 3139 Earhart Expressway

A future interchange joining Causeway Boulevard and the Earhart Expressway is planned. An Environmental Assessment on the potential interchange was completed in 2008 with a Finding of No Significant Impact (FONSI). However further analysis from a traffic study indicated that unaccounted for local traffic congestion could result from the preferred interchange design selected previously. Therefore a Supplemental Environmental Assessment (SEA) was undertaken while additional traffic flow improvements were identified. The SEA was completed by 2015, followed by a public comment period.8

U.S. 90 Business


Pontchartrain / Westbank Expressways

Not really a business route in the conventional sense, U.S. 90 Business extends the Pontchartrain Expressway southeast from Interstate 10 between Central City and Downtown New Orleans to the Crescent City Connection bridges across the Mississippi River. The cantilever spans join the Pontchartrain Expressway with the Westbank Expressway as U.S. 90 Business turns south to the city of Gretna.

The Westbank Expressway hooks southeast from Algiers in New Orleans to Ames Avenue in Marrero as a full freeway. West through Westwago, the expressway travels at-grade with a wide median to end at Avondale and U.S. 90. Future I-49 signs appear along the route.

Frontage roads accompany the elevated portion of the Westbank Expressway through Marrero, Harvey and Gretna. The surface roads are the former expressway mainline from when it traveled at-grade with signalized intersections. They converge below the high rise bridge above Harvey Canal to dip below the industrial waterway through Harvey Tunnel. The four-lane tube is of 1950s vintage with narrow lanes and a median separator.6

The Westbank Expressway was reconstructed during the 1980s. The project built 8.5 miles worth of six-lane viaduct and the Harvey Canal Bridge. The freeway project cost $365 million.5

The Pontchartrain Expressway was expanded to include a new eastbound viaduct from 1980 to 1996. Construction during the $471 million project also added new flyovers linking I-10 west with U.S. 90 Business west and vice versa. The westbound viaduct along the freeway was also replaced and a reversible two lane HOV roadway was erected between the two carriageways. The HOV roadway runs from the Algiers approach to the Crescent City Connection west to Earhart Boulevard and Loyola Avenue by the Superdome.

U.S. Highways

U.S. 51


U.S. 51

Only 3.5 miles of U.S. 51 travels independent of Interstate 55 between the south end at LaPlace and the Tangipahoa Parish city of Ponchatoula. The short stretch through the community of LaPlace constitutes a five lane boulevard between U.S. 61 (Airline Highway) and a diamond interchange with Interstate 10. An adjacent half diamond interchange connects U.S. 51 with the elevated I-55 northward over the isthmus separating Lake Maurepas and Pontchartrain. The 28 mile long overlap concludes on the south side of Hammond. A nine mile long Business Loop also joins I-55/U.S. 51 with Ponchatoula and Downtown Hammond from Exit 23 north to U.S. 190 (Thomas Street).

All of old U.S. 51 is passable as it parallels the Interstate 55 viaduct northward from LaPlace to Exit 22 by the South Slough outside Ponchatoula. The two lane roadway travels at grade by the abandoned settlement of Ruddock to a high level bridge across Pass Manchac to Manchac. Manchac is home to a restaurant, several docks and a handful of dwellings. A number of fishing camps and Port Manchac line the old highway further north.

Historically, U.S. 51 overlapped with U.S. 61 southeast to New Orleans for route continuity. The alignment through La Place bypassed a narrow stretch of Main Street.

U.S. 61


U.S. 61 – Airline Highway

Originally overlapped with U.S. 51 and U.S. 65, U.S. 61 was superseded by Interstate 10 from Baton Rouge southeastward to New Orleans. Known as Airline Highway or Airline Drive, U.S. 61 varies with four to six lanes either as a divided highway or commercial arterial throughout the metropolitan area. The highway offers an alternative to Interstate 10 from Laplace and Reserve eastward to Saint Rose and Kenner. A six lane stretch through Metairie crosses paths with Causeway Boulevard (LA 3046) at a rotary interchange built in 1957, where an elevated traffic circle connects ramps with both roadways. Entering New Orleans at Holly Grove, U.S. 61 transitions onto Tulane Avenue to parallel I-10 (Pontchartrain Expressway) through Mid-City to end at U.S. 90 (Broad Avenue).

U.S. 90


U.S. 90 – Chef Menteur / Jefferson Highway

U.S. 90 follows a somewhat convoluted street routing throughout the city of New Orleans and Jefferson Parish. The highway enters Orleans Parish across the Rigolets to run southwest along a narrow strip of land separating Lakes Pontchartrain from St. Catherine. Elevated homes, fish camps and boat docks line the route as it travels just 4 to 10 feet above sea level. Spanning Chef Menteur Pass, U.S. 90 reaches the community of Venetian Isles. A short distance west from there is a levee and the south end of U.S. 11.

Crossing another levee, U.S. 90 enters the Viavant – Venetian Isles area at just two feet above sea level. The four lane route expands to include a grassy median from Industrial Parkway west by the NASA Michoud Assembly Facility to Interstate 510. Chef Menteur Highway separates industrial areas to the south from the Read Boulevard and Plum Orchard residential street grid through to the first meeting with Interstate 10.

Interstate 10 passes south of U.S. 90 as Chef Menteur Highway travels west through the Pines Village community to a lift bridge across the Inner Harbor Navigational (Industrial) Canal. Beyond a retail area in Gentilly Woods, U.S. 90 shifts onto a tree lined boulevard (Gentilly Boulevard) west to Dillard University and the couplet of New Orleans and Allen Streets. The one-way pair converges south of I-610 as Broad Street to the Fair Grounds and 7th Ward communities.

Broad Street angles U.S. 90 southwest to Tulane Avenue, where U.S. 61 begins and U.S. 90 turns southeast through Tulane – Gravier to the Claiborne elevated freeway for Interstate 10. Claiborne Avenue parallels the I-10 viaduct southwest by Caesars Superdome to emerge from the freeway at Central City. Prior to sometime after the 1960s, U.S. 90 used Canal Street between Broad Street and Claiborne Avenue.

Advancing from Central City, U.S. 90 takes the curved alignment of Catherine Street northwest to Tulane University and East Carrollton to exit the city from the Leonidas community. Beyond the Orleans Parish line, U.S. 90 follows Jefferson Highway through a mixture of industrial and residential areas through Jefferson to the Huey P. Long Bridge at Clearview Parkway (LA 3152). Carrying two railroad tracks and six lanes of traffic across the Mississippi River, the high level cantilever bridge was expanded during a $1.2 billion project between 2006 and 2013.

A short stretch of freeway extends south from the Huey P. Long Bridge through Bridge City to Louisiana 18 west. South from there, U.S. 90 Business returns to U.S. 90 from the Westbank Expressway at a folded diamond interchange. The remainder of the drive west through Avondale, Mimosa Park and Boutte travels at grade as a busy trucking corridor to Interstate 310. Area wetlands along this corridor will likely require the Interstate 49 South corridor to parallel U.S. 90 along elevated roadway. The high costs with a bridge system may lead to a truncation of the route to end at I-310 and U.S. 90 at Boutte instead of to the east along the West Bank Expressway.

State Highways

Louisiana Highway 23


LA 23 – Belle Chasse Highway

LA 23 begins at Gretna opposite Louisiana 18 (Lafayette Street) at the Westbank Expressway (U.S. 90 Business). The state highways travels southward along a busy arterial route to the Belle Chase Bridge and Tunnel across the Intracoastal Waterway. Beyond the crossing, LA 23 curves southwest to Belle Chase and NAS JRB New Orleans. Becoming rural, LA 23 extends another 66 miles as a Great River Road along the Mississippi River to Venice and the river delta.

Prior to the completion of the Greater New Orleans Bridge (U.S. 90 Business), LA 23 utilized the Jackson Avenue Ferry between Gretna and the city at Irish Channel and St. Thomas. Jackson Avenue extended the route northward to U.S. 90 (South Claiborne Avenue) in the city. Together with Jackson Avenue and Huey P. Long Avenue south to 4th Street in Gretna, both alignments were historically a part of LA 2. The rest of the highway south of Harvey was designated as LA 31. The Pelican State renumbered its highway system by 1957-58.

Louisiana Highway 39


LA 39 – Claiborne Ave / Robertson St

This state highway begins at the turn of U.S. 90 from Claiborne to Tulane Avenues at the Central Business District in New Orleans. LA 39 runs along the side or underneath the Claiborne elevated freeway of I-10 northeast to St. Bernard Avenue in the Seventh Ward. LA 39 emerges there with flyover ramps connecting the freeway from the Claiborne Avenue neutral ground at Pauger Street.

Claiborne Avenue forms a couplet with Robertson Street east from Elysian Fields Avenue through the St. Roch and St. Claude communities. The one way pair converge at a lift bridge across the Inner Harbor Navigational (Industrial) Canal into the Ninth Ward. Judge Perez Drive continues LA 39 east into St. Bernard Parish to Chalmette.

Southeast from Chalmette, LA 39 arcs through a mixture of residential and agricultural areas to intersect LA 46. The two highways form a wrong-way overlap west to Poydras. The remaining 38 miles of LA39 then mirror the course of the Mississippi River southward to Bohemia.

The original LA 39 followed the current route of LA46 from Elysian Fields Avenue eastward to Chalmette. The two highways switched places by the late 1960s.

Louisiana Highway 406


LA 406 – Woodland Hwy / River Rd

Traveling 6.0 miles along Woodland Highway and River Road, LA 406 arcs north from LA 23 at Belle Chase to Patterson Road along the Mississippi River in southeast New Orleans.

Louisiana Highway 407


LA 407

LA 407 crosses the Intracoastal Waterway between Orleans and Plaquemines Parish across the Algiers Cutoff Canal Bridge. The fixed crossing travels 100 feet above the canal waters below. The bridge opened in 1985 at a cost of $20.8 million, replacing a vertical lift truss span.5

Louisiana Highway 3021


Elysian Fields Avenue

Elysian Fields Avenue is a tree lined parkway north from Peters Street in the Marginy neighborhood to Ponchartrain Beach and the University of New Orleans. The four lane boulevard sees high speed ramps at I-10 leftover from the Riverfront Expressway proposal and a diamond interchange with I-610 at Gentilly. Providing an alternate route to the French Quarter, Elysian Fields Avenue is designated as LA 3021 for 1.84 miles south from U.S. 90 (Gentilly Boulevard) to LA 39 (Claiborne Avenue) and as LA 46 between Claiborne and St. Claude Avenues.

Elysian Fields Avenue - North
Elysian Fields Avenue northbound at LA 46 (Saint Claude Avenue). LA 46 west turns onto Elysian Fields Avenue north to end five blocks ahead at LA 39 (Claiborne Avenue) in the Seventh Ward. LA 46 east travels through the St. Claude and Bywater neighborhoods to the Lower 9th Ward. According to a 1966 map, this stretch of LA 46 was originally signed as LA 39. 12/21/07
LA 3021 separates to accommodate on-ramps from I-10 between Galvez Street and Florida Avenue. The pair of wye interchanges were built between Elysian Fields Avenue and the elevated freeway as part of the canceled Riverfront Expressway. 12/21/07
A four lane viaduct along Elysian Fields Avenue (LA 3021) north spans Florida Avenue and a CSX Railroad midway between ramps with I-10 and I-610 at the St. Roch neighborhood. Removed by 2007, this vintage sign bridge directed motorists to the Florida Avenue off-ramp on this stretch. 03/20/02
A diamond interchange connects I-610 with LA 3021 (Elysian Fields Avenue) at Benefit and Humanity Streets on the south side of the Gentilly Terrace neighborhood. I-610 east merges onto I-10 east nearby while the freeway westbound continues toward City Park. 03/20/02

LA 3152 – Clearview Parkway

Completed by 1973, Clearview Parkway links the Huey P. Long Bridge (U.S. 90) with U.S. 61 (Airline Drive). Carrying six lanes of traffic, the congested arterial bisects residential areas northward from Airline Drive to a cloverleaf interchange with Interstate 10. Flyovers replaced an antiquated interchange joining Clearview Parkway, Jefferson Highway and the Huey P. Long Bridge as part of the seven year upgrade of the cantilever span.

Other Streets and Highways

Airport Road

Airport Road comprises a limited access highway in the city of Kenner. The four lane highway connects Interstate 10 and Veterans Boulevard with the passenger terminal of Louis Armstrong New Orleans International Airport (MSY) and U.S. 61 (Airline Drive).

A concrete divider and decorative lighting replaced the double yellow line separating traffic on Airport Road by 2002. Speed limits were also increased from 35 to 45 miles per hour.

Airport Road - North
Approaching the partition of traffic for Veterans Boulevard and the eastbound flyover to Interstate 10 on Airport Road north. 12/28/02
Entering the half diamond interchange with Veterans Boulevard on Airport Road north. There is no direct access to I-10 west. Instead motorists must take Veterans Boulevard east to LA 49 (Williams Boulevard) north and access the freeway there. 12/28/02

Bourbon Street

One of the main tourist destinations for New Orleans and the Vieux Carre, Bourbon Street flows northeast from Carondelet Street to Pauger Street. The street is open to vehicular traffic by day and restricted to pedestrian traffic at night. An array of businesses line the street including souvenir shops, jazz themed restaurants and clubs, bars, and adult entertainment. Hundreds or thousands pack the sidewalks and street well into the early morning hours as barricades block vehicular traffic.

Canal Street

Canal Street forms a four to six lane thoroughfare from the Mississippi riverfront at Harrah’s casino northwest to City Park Avenue. An RTA Streetcar line accompanies the boulevard from end to end.

During colonial times, Canal Street was the location of the western wall protecting the original settlement of New Orleans (which consisted of just the French Quarter). Canal Street derives its name from a canal that was never dug within its neutral ground. During the mid 19th century, Canal Street was renamed to Touro Street only to be renamed Canal Street by public demand.9

Carondelet Street

Carondelet Street flows north from Central City through the Central Business District to become Bourbon Street at Canal Street. The Saint Charles Streetcar line accompanies Carondelet from Howard Avenue to Canal Street at the French Quarter.

Jackson Street

A lost highway in a sense, Jackson Street once carried U.S. 90 and LA 2 from a ferry landing on the Mississippi River northward to Claiborne Avenue. The historic route for U.S. 90 coincided with a ferry landing on the west bank of the river at Harvey. When U.S. 90 was later relocated on its current course near Tulane University, LA 23 took over the Jackson Street Ferry and surface route from Harvey northbound until the Greater New Orleans Bridge opened.

Saint Charles Avenue

One of many divided boulevards within the city of New Orleans, Saint Charles Avenue doubles as a streetcar line. The four lane thoroughfare links Tulane University, the Garden District, the Central Business District and the French Quarter at Royal Street. Cars on the Saint Charles Streetcar line are painted green.
