I-110 at Baton Rouge.

I-110 begins at Downtown Baton Rouge at an interchange with Interstate 10, just east of the Horace Wilkinson Bridge over the Mississippi River. I-110 runs on 2×3 lane overpasses along the east side of downtown and has left exit ramps. I-110 then makes a major S-turn and passes through the northern neighborhoods of Baton Rouge, partly on overpasses. To the west is a large oil refinery. To the north of Baton Rouge is a large 4-level stack with US 61 and US 190. I-110 then passes the Baton Rouge Metropolitan Airport and terminates at the northern edge of the city on US 61, which continues to Natchez, Mississippi.

Before the construction of I-110, US 61 passed through downtown Baton Rouge. In 1941, the Baton Rouge bypass, which was numbered as the US 61 Bypass, opened. I-110 is built mostly parallel to US 61.

Interstate 110 predates the Interstate Highway system and was opened in the mid-1950s in downtown Baton Rouge. This is the twisty substandard route. Construction of the rest of the motorway began in 1961 and has been opened in phases northwards. The final section opened to traffic in 1984 and included the stack interchange with US 61/190 on the north side of town.

Traffic intensities

Daily 93,000 vehicles operate at the I-10 interchange, 65,000 vehicles just north of Downtown Baton Rouge, 66,000 vehicles south of US 61/US 190, and 52,000 vehicles near Baton Rouge Airport. This drops to 29,000 vehicles at the end of I-110.

I-220 at Shreveport.

Interstate 220 forms Shreveport ‘s northern bypass and begins and ends at Interstate 20. The western interchange also provides access to State Highway 3132, which forms Shreveport’s southern bypass. On the western portion of the route, I-220 crosses Cross Lake with an overpass. Also on the north side of town is an interchange with Interstate 49 toward Texarkana and a bridge over the Red River. I-220 has 2×2 lanes for its entire length. The eastern part of I-220 partly has a wide median strip.


Before the construction of the Interstate Highways, US 80 was the through route for east-west traffic. Interstate 20 was built through Shreveport before I-220. I-20 opened in 1965, I-220 followed more than a decade later and was constructed mainly in the late 1970s and early 1980s. The last section was the bridge over Cross Lake which opened in 1991. This allowed traffic to bypass Shreveport, but the light congestion on I-20 through the city means that relatively little through traffic takes I-220. I-220 is part of the through route of I-49, as it is missing near downtown Shreveport and traffic has to detour via I-220. In 2018, the interchange opened with I-49.

Traffic intensities

Every day, 65,000 vehicles travel near the western interchange with I-10, dropping to 40,000 vehicles on the Red River bridge and 28,000 vehicles as far as the eastern interchange with I-10.

Detail of I-310 in Louisiana.

The Luling Bridge over the Mississippi River.

Interstate 310 functions as a western bypass of New Orleans, linking Interstate 10 at the Kenner suburb and US 90 at Boutte. The northern portion of I-310 is mostly on flyovers in the swamps west of New Orleans and has a large and fully elevated interchange with US 61. Interstate 310 crosses the Mississippi River via the Luling Bridge, a cable- stayed bridge. At Boutte, I-310 ends at US 90.


I-310, along with I-510, was once planned as I-420, New Orleans’ never-constructed southern bypass. On October 6, 1983, the first section, the Luling Bridge, opened, and on May 7, 1993, the last link opened to traffic, connecting with I-10. I-310 became the westernmost river crossing of the Mississippi River near New Orleans.

Traffic intensities

Every day 55,000 vehicles travel between I-10 and US 61, 45,000 vehicles cross the Luling Bridge and 44,000 vehicles drive off US 90.
