Highways and roads Interstates Baton Rouge has three interstate highways:
I-10,
I-12 (
Republic of West Florida Parkway), and
I-110 (
Martin Luther King Jr. Expressway). Interstate 10 enters the city from the
Horace Wilkinson Bridge over the Mississippi River, curving at an interchange with Interstate 110 southeast, crossing the LSU lakes and Garden District before reaching an interchange with I-12 (referred to as the 10/12 split). It curves further southeast toward
New Orleans as it crosses Essen Lane near the Medical District. It passes Bluebonnet Blvd and the Mall of Louisiana at exit 162, and leaves Baton Rouge after interchanges with Siegen Lane and Highland Road. Interstate 12 (The
Republic of West Florida Parkway) begins in the city at the I-10/I-12 split east of College Drive, and proceeds eastward, crossing Essen Lane, Airline Hwy, Sherwood Forest Blvd, Millerville Road, and O'neal Lane before leaving the city when crossing the
Amite River. Interstate 110 (The
Martin Luther King Jr. Expressway) stretches 8 miles in a north–south direction from the east end of the Horace Wilkinson Bridge to Scenic Highway in Scotlandville, Louisiana. It passes through downtown, North Baton Rouge, and
Baton Rouge Metro Airport before ending at Scenic Highway.
U.S. highways and major roads Baton Rouge has two U.S. highways, along with their business counterparts:
Airline Highway (
US 61) and
Florida Boulevard. U.S. 190 enters the city from the
Huey P. Long Bridge, beginning a concurrency with U.S. 61 after an interchange with Scenic Highway, near Scotlandville. Its name is Airline Highway from this interchange to the interchange with Florida Blvd. At this interchange, U.S. 190 turns east to follow Florida Blvd through Northeast Baton Rouge, exiting the city at the Amite River. U.S. 61 enters Baton Rouge as Scenic Highway until it reaches Airline Highway (U.S. 190). It becomes concurrent with U.S. 190 until Florida Blvd, where it continues south, still called Airline Highway. It passes through Goodwood and Broadmoor before an interchange with I-12. It continues southeast past Bluebonnet Blvd/Coursey Blvd, Jefferson Hwy, and Sherwood Forest Blvd/Siegen Lane before exiting the city at Bayou Manchac. U.S. 61/190 Business runs west along Florida Boulevard (known as Florida Street from Downtown east to Mid City) from Airline Highway to River Road in downtown. The cosigned routes run from Florida St. north along River Road, passing the
Louisiana State Capitol and Capitol Park Complex before intersecting with Choctaw Drive. North of this intersection River Road becomes Chippewa Street and curves to the East. U.S. 61/190 Business leaves Chippewa Street at its intersection with Scenic Highway. The route follows Scenic Highway to Airline Highway, where it ends. North of Airline on Scenic and East of Scenic Highway on Airline is US 61. U.S. 190 is East and West of Scenic on Airline Highway. These are important surface streets with designated state highway numbers: Greenwell Springs Road (
LA 37), Plank Road/22nd Street (
LA 67), Burbank Drive/Highland Road (
LA 42), Nicholson Drive (
LA 30), Jefferson Highway/Government Street (
LA 73), Scotlandville/Baker/Zachary Highway (
LA 19), Essen Lane (
LA 3064), Bluebonnet Blvd/Coursey Blvd (
LA 1248), Siegen Lane/Sherwood Forest Blvd (
LA 3246), and Perkins Road/Acadian Thruway (
LA 427).
Traffic issues and highway upgrades According to the 2008 INRIX National Traffic Scorecard, which ranks the top 100 congested metropolitan areas in the U.S., Baton Rouge was the 33rd-most congested metro area in the country. At a population rank of 67 out of 100, it has the second-highest ratio of population rank to congestion rank, higher than even the
Los Angeles-
Long Beach-
Santa Ana metropolitan area, indicating a remarkably high level of congestion for the comparatively low population. According to the Scorecard, Baton Rouge was the only area out of all 100 to show an increase in congestion from 2007 to 2008 (+ 6%). The city also tied for the highest jump in congestion rank over the same period (14 places). Interstate 12 used to have a major bottleneck at O'Neal Lane. The interstate was three lanes wide in each direction to the O'Neal Lane exit, where the interstate abruptly became two lanes in each direction and crossed the narrow Amite River Bridge. This stretch of road, called "a deathtrap" by one lawmaker, had become notorious for traffic accidents, many with fatalities. In 2007, ten people died in traffic accidents within a three-month period on this section of road. In 2009, Governor
Bobby Jindal and the Baton Rouge legislative delegation allocated state and federal funding to widen I-12 from O'Neal Lane to Range Avenue (Exit 10) in Denham Springs. The construction was completed in 2012 and has significantly improved the flow of traffic. In 2010, The
American Reinvestment and Recovery Act provided committed federal funds to widen I-12 from the Range Avenue Exit to
Walker, Louisiana. Noticing the significant improvement in commute times, Jindal further funded widening to Satsuma, Louisiana. Interstate 10 West at Bluebonnet Road also ranked within the top 1000 bottlenecks for 2008, and I-10 East at Essen Lane and Nicholson Drive ranked not far out of the top 1000. A new exit to the
Mall of Louisiana was created in 2006, and the interstate was widened between Bluebonnet Blvd and Siegen Lane. But the stretch of I-10 from the I-10/I-12 split to Bluebonnet Blvd was not part of these improvements and remained heavily congested during peak hours. In response, a widening project totaling at least $87 million began in late 2008. Interstate 10 was widened to three lanes over a five-year period between the I-10/I-12 split and Highland Road. In 2010, the
American Reinvestment and Recovery Act provided supplemental funding for this project to extend to the Highland Road exit in
East Baton Rouge Parish. Surface streets in Baton Rouge are prone to severe congestion. But roads are beginning to handle the number of vehicles using them after years of stagnation in road upgrades. Baton Rouge Mayor
Kip Holden has instituted an extensive upgrade of East Baton Rouge Parish roads known as the Green Light Plan, geared toward improving areas of congestion on the city's surface streets. With its first project completed in 2008, it has seen numerous others reach completion as of 2015, with several more under construction and still others yet to break ground. A circumferential loop
freeway was proposed for the greater Baton Rouge metro area to help alleviate congestion on the existing through-town routes. The proposed loop would pass through the outlying parishes of
Livingston (running alongside property owned and marketed as an industrial development by Al Coburn, a member of President Mike Grimmer's staff), Ascension, West Baton Rouge, and Iberville, as well as northern East Baton Rouge Parish. This proposal has been subject to much contention, particularly by residents living in the outer parishes through which the loop would pass.
Commuting The average one-way commute time in Baton Rouge is 26.5 minutes, slightly less than the U.S. average of 27.1 minutes. Interstates 10, 110 and 12, which feed into the city, are highly traveled and connected by highways and four-lane roads that connect the downtown business area to surrounding parishes. According to the 2016
American Community Survey, 81.9% of working Baton Rouge residents commuted by driving alone, 8.5% carpooled, 3% used public transportation, and 2.4% walked. About 1.2% used all other forms of transportation, including taxi, bicycle, and motorcycle. About 3.1% worked at home. In 2015, 10.4 percent of Baton Rouge households lacked a car, and increased slightly to 11.4 percent in 2016; higher than average for a city of its size. The national average was 8.7 percent in 2016. Baton Rouge averaged 1.55 cars per household in 2016, compared to a national average of 1.8.
Buses and other mass transit Capital Area Transit System (CATS) provides urban transportation throughout Baton Rouge, including service to
Southern University,
Baton Rouge Community College, and
Louisiana State University. Many CATS buses are equipped with bike racks for commuters to easily combine biking with bus transit. Greyhound Bus Lines, offering passenger and cargo service throughout the United States, has a downtown terminal on Florida Boulevard.
Shipping The
Port of Baton Rouge is the ninth-largest in the United States by tonnage shipped, and is the farthest upstream Mississippi River port capable of handling
Panamax ships. The
Yazoo and Mississippi Valley station had passenger service until the mid-1960s. The Kansas City Southern depot hosted the
Southern Belle, the final train to serve the city, until 1969. Since 2006, Baton Rouge and New Orleans leaders as well as the state government have been pushing to secure funding for a new high-speed rail passenger line between downtown Baton Rouge and downtown New Orleans, with several stops in between. A new
New Orleans–Baton Rouge passenger rail service was included as part of the "Amtrak Connects US" expansion vision. == Sister cities ==
