Interstate 49



Interstate 49, currently entirely within the state of Louisiana, connects Lafayette and Shreveport via Alexandria along a 200-mile freeway. The northern segment of Interstate 49 within the city of Shreveport was only completed in the late 1990s, while the section between Opelousas and Lafayette was completed in stages during the early 1980s.

High Priority Corridor

Future Interstate 49 from Shreveport to Kansas City is part of High Priority Corridors 1 and 72: North-South Corridor, while the future section between New Orleans and Lafayette is part of High Priority Corridor 37: U.S. 90.

Future Aspirations

The future shows a much longer path for Interstate 49, with extensions in the works to both the north and south. It will extend north to Kansas City via the U.S. 71 corridor and southeast to New Orleans via the U.S. 90 corridor.

Louisiana: Interstate 49 South (High Priority Corridor 37)

Future Interstate 49 corridor signage is already in place from the southern terminus in Lafayette southeastward via U.S. 90 to New Orleans. Interstate standard upgrading is underway along U.S. 90 near New Iberia and Morgan City, and Interstate 49 will culminate its journey along the Westbank Expressway before terminating at Interstate 10 in downtown New Orleans. The majority of this section (from Lafayette east to the junction of Interstate 310 and secret Interstate 910) was approved as "Future Interstate 49" by AASHTO's Route Numbering Subcommittee on November 6, 1998. The section between Interstate 310 and Interstate 10 (secret Interstate 910) was designated as Future Interstate 49 on October 1, 1999.

Interstate 49 through Lafayette received approval January 8, 2003 by the Federal Highway Administration. The motion allows for funding to commence on the planned five-mile $350 million viaduct between Interstate 10 and the Lafayette Regional Airport. Preliminary engineering for the project may be complete within a year at a cost of $500,000. Not all residents are thrilled with this progress, as many residents near the projected path of the freeway fear harm will be done to developed and mostly poor neighborhoods nearby. In related opposition, legal action has been pursued to move the project eastward into Saint Martin Parish. However, planners contend that the project complies with all applicable laws, and it appears very unlikely that the highway will be relocated from the original planned routing.2

Financing is underway to pay for the $4.9 billion project that Interstate 49 entails. A Congressional group met in 2003 at the New Orleans International Airport to discuss the corridor and funding related issues. Representative Tom Pitre of Wisconsin indicates that the House is drafting a $375 billion six-year proposal that will allocate Louisiana $4.28 billion which will help pay for Interstate 49 within the state. On the docket for Interstate 49 in Louisiana is the creation of a 36-mile portion of freeway between Shreveport and the Arkansas state line and the upgrading of U.S. 90 between Lafayette and New Orleans to Interstate standards. Total costs within Louisiana are estimated to be $2.3 billion. The state will cover 20% of the costs.3

Overview: Interstate 49 North (High Priority Corridor 1)

In addition, Interstate 49 is planned for a northward extension along the U.S. 71 Corridor through Northern Louisiana, Arkansas, and Missouri. Much of the existing U.S. 71 freeway, as well as Interstate 540 in Arkansas north of Interstate 40 and Interstate 130 in Texarkana, will become part of Interstate 49. These extensions to Interstate 49 are authorized as part of the National High Priority Corridor designation. Interstate 49 is part of the NHS/ISTEA/TEA-21 High Priority Corridor 1 between Shreveport and Kansas City and Corridor 37 for the Interstate 49 South extension from Lafayette southeast to New Orleans.

Louisiana: Interstate 49 North

Presently Interstate 49 terminates at Interstate 20 near downtown Shreveport. Interstate 49 will shift to Louisiana 3132 (Inner Loop Expressway) and the western portion of Interstate 220 upon completion of the Interstate 49 corridor between Shreveport and Arkansas. It was originally thought that there will be no continuation of the in-city routing of Interstate 49 northward as the route will bypass the city to the west. However new efforts have emerged by the city of Shreveport and local officials to build the I-49 Inner City Connector. The Connector is approximately 3.6 miles in length, leading north from I-20 along Peter Harris Drive to Ford Street and then northwesterly along Twelvemile Bayou to I-220. A Feasibility Study and Environmental Inventory was completed in 2010 and currently an Environmental Impact Statement is being prepared.

Otherwise if I-49 shifts to the bypass, the existing segment of Interstate 49 between the symmetrical stack interchange at Louisiana 3132 to Interstate 20 will have to be renumbered. It is possible that this may become Interstate 149. Continuation of I-49 North from Interstate 220 will occur at a new interchange one mile to the west of the current U.S. 71/Louisiana 1 interchange (Exit 7).1

Interstate 49 North is broken into 11 segments:

  • A - Louisiana 168 to the Arkansas line
  • B - Parish Road 16 (Mira-Myrtis Road) to Louisiana 168
  • C - Louisiana 2 to Parish Road 16 (Mira-Myrtis Road)
  • D - U.S. 71 (south of Hosston) to Louisiana 2
  • E - Louisiana 170 to U.S. 71 (south of Hosston)
  • F - Louisiana 530 to Louisiana 170
  • G - Louisiana 169 to Louisiana 530
  • H - Louisiana 173 to Louisiana 169
  • I - Louisiana 1 to Louisiana 173
  • J - Louisiana 3194 (Dr. Martin Luther King Drive) to Louisiana 1
  • K - Interstate 220 to Louisiana 3194 (Dr. Martin Luther King Drive)

Groundbreaking for the first phase (Segment B) of the new Interstate 49 corridor between Interstate 220 and the Arkansas State Line occurred north of Mira at the intersection of Parish Road 16 and Parish Road 25 on Thursday, April 7, 2005.8 This section of Interstate 49 is estimated to cost $385 million.9

Work continues in 2007 on Interstate 49 at the state line, where crews are moving dirt on a 6.6-mile long section near the Arkansas state line. State money was secured to bridge the 20% funding gap, allowing LADOTD to work on seven of 11 proposed freeway segments between Interstate 220 and the border. Optimistic officials hoped to see new 6.6-mile section of future Interstate 49 open in 2010, if not 2009.9

LADOTD anticipated having most of Interstate 49 North, from Louisiana 1 (Segment I) to Louisiana 168 south of the Arkansas state line (Segment A), open and signed as I-49 by November 2013.25 This included a temporary end at Louisiana 168 until Arkansas completed its extension of Arkansas 549 southward, projected for May 2014. A widening of LA-168 east from Future I-49 to U.S. 71 was proposed to augment the connection to Arkansas until the freeways were seamlessly connected. The gap between LA 168 and U.S. 71 north of Kiblah, Arkansas opened to traffic after a ribbon cutting ceremony held by officials from both states on the morning of November 10, 2014.28

Work on Segment K went to bid in December 2013, two years after expected due to funding issues, for the $70-100 million project.22,24 It may open in 2016.25


Future Interstate 49 is nearing completion from the Louisiana state line to Interstate 30 at Texarkana. This includes what was previously planned as Future Interstate 130 and the Arkansas 549 freeway between Exit 4 (U.S. 71) near Doddridge and U.S. 59 & 71 north of McKinney Bayou and Texarkana. The first segment of this freeway route (from Fouke to Texarkana) was completed on December 16, 2004.7

Work in Texarkana focused on upgrading the Arkansas 245 freeway to Interstate standards from the interchange with AR-549, southeast of Texarkana, to Arkansas Boulevard, where I-49 follows branches northeast to I-30 along a new alignment. A ribbon-cutting ceremony was held on April 30, 2013 for the 10.6-mile segment of new I-49 between Arkansas Boulevard and the state line north of Texarkana. Wet weather delayed opening of the roadway to May 15.23

A half-diamond interchange with U.S. 59 & 71 will eventually connects with a six to eight mile alignment proposed through Bowie County, Texas. This alignment will include an interchange with Interstate 369.

The Arkansas State Highway and Transportation Department is currently reviewing funding options for Interstate 49 between Texarkana north to Fort Smith; currently, no freeway route exists between Texarkana and Fort Smith. Work commenced in 2010 on a section of Future Interstate 49 between County Route 8 and Arkansas 22 in the Fort Smith / Fort Chaffee area. 2.7 miles of roadway embankment, two overpasses and four box culverts for the new freeway were completed in fall of 2011.19 Additional work builds an interchange for Arkansas 22 (Rogers Avenue) and diamond interchanges at Massard Road and Roberts Boulevard as part of the overall $57.65-million, seven-mile stretch of freeway on the Chaffee Crossing section of I-49. The contract involving the construction of 0.635-miles of roadway and new interchange with U.S. 71 at the south end was let May 2, 2012.21 This work will be completed in 2014 and includes an interchange with U.S. 71.

A bridge across the Arkansas River for future Interstate 49, north of AR-22, was estimated to cost $300 million in 2010.

From Fort Smith north to the future Bella Vista bypass, Interstate 540 (built as Arkansas 540) was redesignated as Interstate 49 per approval by AASHTO on October 21, 2013. A 30-day project to resign I-540 & U.S. 71 as I-49 between I-40 and U.S. 71 Business south of Bella Vista kicked off on April 21, 2014. Signs on other future sections of I-49, including the Bella Vista Bypass and the stretch between U.S. 71 and AR 22 will be dual signed as Future I-49 and Arkansas 549.26

What was then known as Arkansas 540 was initially submitted to AASHTO for inclusion in the Interstate Highway System as Interstate 49 from Interstate 40 near Fort Smith north to the junction with Business U.S. 71 near Fayetteville. On April 25, 1997, AASHTO denied this proposal, indicating that the lack of connecting routes at the northern end would preclude the route from consideration at that time. It was approved as Interstate 540 a few months later by AASHTO, on November 14, 1997.

The Bella Vista Bypass, expected to cost $150.6 million,27 was planned to be constructed as a toll road; this concept was approved by the Arkansas State Highway Commission on April 12, 2006.11 A 3.03-mile section of the Bella Vista Bypass was let in February 2011 with ground breaking on July 8, 2011. This work covers a stretch of roadway between Arkansas 72 west of Hiwasse and Arkansas 72 southeast of Hiwasse.20 Work on the $19.8-million contract wrapped up on April 22, 2014.27

A second Bella Vista Bypass project was let May 2, 2012 and pertains to 2.377 miles of two-lane roadway leading north from the AR-72 interchange west of Hiwasse to County Road 34.


Interstate 49 was made official in Missouri on December 12, 2012 in a ceremony held at Joplin East Middle School at noon. The designation applies to 180 miles of U.S. 71 between Kansas City and Joplin.

The Missouri Department of Transportation (MoDOT) approved highway construction on August 4, 2010 on a number of projects to upgrade U.S. 71 between Joplin and Kansas City to Interstate standards in anticipation of redesignating the highway to I-49 by December 2012.3 Four interchanges were completed at a cost between $4 and 5 million along Future Interstate 49 / U.S. 71 by September 2010. These include Missouri 126, Routes DD & EE and Routes V & C within Barton County and Missouri 52 in Bates County.13 An interchange between U.S. 71 and Route E, north of Milo, opened to traffic on November 18, 2011.14 Work on an interchange between U.S. 71 and Route TT, midway between Horton and Rich Hill commenced in late January 2012 at a cost of $6.4-million. This exit was planned for completion in early December 2012.15 Further north, work continued with the opening of overpass for 327th Street on August 9, 2012 near Archie. This bridge eliminated an at-grade crossing and was the first of three projects to upgrade U.S. 71 to limited access standards. A diamond interchange with 307th Street and an overpass for 283rd Street will opened later in 2012.18

The Interstate 49 corridor will not utilize the Missouri 249 and 171 corridor east of Joplin due to the present of traffic signals at the diamond interchange between U.S. 71, Missouri 96 and Missouri 171 south. However three options for consideration in the long term are:17

  • Retain the Interstates 44 & 49 overlap, but upgrade the cloverleaf interchange at Exit 18 into a directional interchange.
  • Utilize the Missouri 249 and 171 corridor by upgrading the interchange between U.S. 71, Missouri 96 and 171.
  • Utilize the Missouri 249 and 171 corridor by construction a new freeway connection from near Morgan Heights northeast to Interstate 49, bypassing Carthage to the north.

I-49 south from Pineville to Belle Vista was considered for a toll road3, which AHTD intends to construct as a two-lane facility in phases over six years as indicated in 2010. Missouri's portion of the bypass receives funding in MoDOT's 2013-17 Draft STIP and tentative work is set for 2015, but only if construction of the Arkansas portion of the bypass through to the state line is underway.

Various other improvements have been completed for the U.S. 71 corridor from Pineville north through Joplin, Carthage, Nevada, and Harrisonville. A contract to erect signs with space allocated for Interstate 49 was let in October 2011 in anticipation of the December 2012 planned signing of the route in Missouri. The AASHTO Highways Special Committee on U.S. Route Numbering meeting of October 14, 2011 conditionally approved the Interstate 49 designation in Missouri once the route is fully upgraded to Interstate standards between Pineville and Kansas City. Additionally business loop designations for U.S. 71 at Butler, Joplin, Neosho and Nevada were given conditional approval for renumbering as Business Loops for I-49. A project to install around 1,200 signs for I-49 commenced on February 1, 2012 at a cost of $3.5-million. That work was projected for completion by December 1, 2012.16

In Kansas City, the U.S. 71 freeway/expressway combination is complete. U.S. 71 (a.k.a. Bruce R. Watkins Drive and/or South Midtown Freeway) is now finished between Downtown and the south end of the I-435 loop. It's all Interstate-quality road except for the section between 47th/U.S. 56 and 75th Streets. This section is a parkway with three or four signalized intersections, due to powerful neighborhood associations that objected to a limited access freeway. Missouri DOT designed these intersections so that overpasses and ramps could be added at a later date. This route is now a major commuter route from the southern suburbs, and the signalized intersections create traffic jams during peak hours.6 However, it is unlikely that any of these traffic signals would be removed due to local opposition, so Interstate 49 may not be able to follow U.S. 71 into Kansas City downtown.


The 212-mile section of Interstate 49 between Interstate 10 and Interstate 20 in Louisiana was completed on May 1, 1996, at a cost of approximately $1.38 billion. Originally proposed as a toll road, Interstate 49 was constructed with federal funds, some of which were redirected from unconstructed urban Interstates within Louisiana and the rest (153 miles) came from a "supplemental reserve." The bypass around Alexandria was designated the Martin Luther King, Jr. Highway. At the time, Interstate 49 was the longest Interstate to begin and end within the same state.10

Perspective from Interstate 10 west
The end of Interstate 49 South as originally envisioned was the interchange where Interstate 10 and U.S. 90 Business (unsigned Interstate 910) come together near Downtown New Orleans. This end point is not entirely certain however, as funding woes have questioned whether or not building Interstate 49 east to New Orleans from the Boutte area is financially feasable. One proposal considered is to reroute Interstate 49 northeast along Interstate 310 and end it near the Jefferson Parish line.

A massive stack interchange exists between Interstate 20 and the northern terminus of Interstate 49. This photograph looks at the impressive structure from westbound Interstate 20. Embedded within the Interstate 49 stack is Exit 17A for Linwood Avenue and Lakeshore Drive.
Eventually Interstate 49 will continue northward to Fort Smith, Arkansas. When the alignment north of Shreveport is completed, Interstate 49 will reroute along the Louisiana 3132/Inner Loop Expressway and Interstate 220 to around milepost 6 before departing on an independent alignment. Existing Interstate 49 within the Inner Loop Expressway to Interstate 20 will likely be renumbered as a spur of Interstate 49.
