Interstate 49


Envisioned as a nearly 850 mile route from New Orleans to Kansas City, Interstate 49 is currently signed on four distinct segments from the Gulf Coast to the Midwest. The original 208-mile stretch runs north from Lafayette to Shreveport. Subsequent sections are posted from Blanchard, Louisiana north to Texarkana, between Alma and Bentonville, Arkansas, and between Pineville and Grandview, Missouri. Additional sections, all signed as Arkansas 549, include the Bella Vista Bypass section, currently under construction along the south and west sides of Bella Vista, and the Chaffee Crossing section, scheduled to open on July 14, 2015 to the southeast of Fort Smith, Arkansas.

Future Interstate 49 corridor signage appears 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 I-310 and I-10 (unsigned I-910) was designated as Future I-49 on October 1, 1999.

High Priority Corridor

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

Current construction along Interstate 49 South includes building a railroad overpass along U.S. 90 between Louisiana 85 and 668 in Iberia Parish. Costing $10-15 million, the project should go to bid in 2016. Within Lafayette Parish, a $50-70 million interchange between U.S. 90 at Ambassador Caffery is currently under design through to early 2016. $5-7.5 million frontage road construction from Ambassador Caffery Parkway to Captain Cade Road will be bid upon in 2016/17. Additional frontage roads will be added along side U.S. 90 from Albertson Parkway to Southpark Road starting in 2016/17. Work in St. Mary Parish will add an interchange with U.S. 90 at Louisiana 318, with two-years of construction of the $30-50 million project commencing by early 2016.

Presently Interstate 49 has a gap between Interstate 20 near Downtown Shreveport and Louisiana 1 to the east of Blanchard. Original plans shifted I-49 onto Louisiana 3132 (Inner Loop Expressway) and the western portion of Interstate 220 to bypass Shreveport. However efforts emerged from the city of Shreveport and local officials to build the I-49 Inner City Connector. The Connector is approximately 3.6 miles in length. If built, I-49 would continue 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 May 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 and Interstate 20 will have to be renumbered. Continuation of I-49 North from I-220 (Segment K) will stem north from a new interchange one mile to the west of the current U.S. 71/Louisiana 1 interchange (Exit 7).1

Work on Segment K, I-49 between I-220 and LA 1 near Blanchard, went to bid in December 2013. This was two years after expected due to funding issues for the $70-100 million project.22,24 It is estimated for completion in 2016-17.25

A half-diamond interchange with U.S. 59 & 71 at the north end of I-49 will eventually connect with a six to eight mile alignment proposed through Bowie County, Texas. This alignment will include an interchange with Interstate 369.

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

Parcel map showing the path of the Bella Vista Bypass. The road is proposed at 20 miles overall, 15 of which are in Arkansas. A three mile stretch of the super-two freeway, between AR 72 west of Hiwasse and AR 72 south of Hiwasse, opened to traffic in 2014.

A second Bella Vista Bypass project was let May 2, 2012 pertaining to 2.377 miles of two-lane roadway leading north from the AR 72 interchange west of Hiwasse to County Road 34. Work on this section runs through late 2015. A third portion is also underway to extend AR 549 east from AR 72 to U.S. 71 Business in Bella Vista. The 6.36-mile portion is being built at a cost of $52.6-million. It is scheduled for completion in mid-2016.31

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 is constructing as a two-lane facility in phases over six years as indicated in 2010. Missouri's portion of the bypass received funding in MoDOT's 2013-17 Draft STIP. The right of way is already acquired and plans are ready. MoDOT awaits completion of the Arkansas section to move forward.29

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 complete between Downtown and the south end of the I-435 loop. It is 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.


Interstate 49 was first proposed by Governor John McKeithen as the tolled North-South Expressway in 1965.32 AASHTO approved the initial route of Interstate 49 between Interstate 20 in Shreveport and U.S. 190 at Opelousas on July 6, 1977. Work commenced on I-49 in April 1980, and the first portion opened was a six-mile segment from U.S. 190 east of Opelousas in September 1983.32 An 18-mile section of I-49 was dedicated on October 13, 1987 within Natchitoches Parish between Louisiana 174 and Louisiana 6.33 That was followed by the completion of a nine mile link in DeSoto Parish, from LA 175 to LA 509, on March 1, 1989.33 Another 35 miles debuted to travelers between Washington and Meeker on May 15, 1989, a few weeks beyond the planned April 22nd opening.34

Work progressed with the opening of another 30 miles of Interstate 49 on November 22, 1989. This section included 18 miles from LA 174 to U.S. 84 in DeSoto Parish and 12 miles from Fierson to LA 526 (Industrial Loop) on the south side of Shreveport.35 Another 7.3 miles of I-49 opened around Boyce to the north of Alexandria on September 26, 1991.36 A development during that time period shifted I-49 from a bypass of Alexandria to a route through Downtown at the urging of merchants, civic leaders and political officials who feared economic losses for the city had it been bypassed. This pushed back the timetable for completion of the 4.5-mile segment through Alexandria to 1996.36

Additional stretches of the original Interstate 49 in Louisiana were dedicated by Governor Edwin Edwards on May 14, 1992 at the U.S. 167 interchange south of Alexandria. The ceremony preceded the opening of a 20-mile section of I-49 between Alexandria and Meeker and a four-mile segment from England Drive to Rapides Station. The 201 miles opened at the time totaled $598 million in costs.37

The 208-mile section of I-49 between Interstate 10 and I-20 in Louisiana was completed on May 1, 1996, at a cost of approximately $1.38 billion. Originally proposed as a toll road, I-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

Louisiana: Interstate 49 South

Interstate 49 through Lafayette received initial approval January 8, 2003 by the Federal Highway Administration. The motion allowed for funding to commence on the planned five-mile $350 million viaduct between Interstate 10 and the Lafayette Regional Airport (LFT). Not all residents were thrilled with this progress, as many near the projected path of the freeway feared impacts to developed and mostly poor neighborhoods nearby. In related opposition, legal action was pursued to move the project eastward into Saint Martin Parish. However, planners contended that the project complied with all applicable laws, and it appeared very unlikely that the highway will be relocated from the original planned routing.2

A Congressional group met in 2003 at the New Orleans International Airport (MSY) to discuss the estimated $4.9-billion corridor and funding related issues. Representative Tom Pitre of Wisconsin indicated that the House was drafting a $375 billion six-year proposal that would allocate Louisiana $4.28 billion which will help pay for Interstate 49 within the state. On the docket for I-49 in Louisiana was the creation of a 36-mile portion of freeway between Shreveport and the Arkansas state line and the upgrade of U.S. 90 between Lafayette and New Orleans to Interstate standards. Total costs within Louisiana were estimated to be $2.3 billion, with the state covering 20% of the costs.3

A number of projects have already upgraded U.S. 90 to freeway standards in Iberia and Lafayette Parishes. These include an $24.5-million interchange at Louisiana 25 opened in January 2011 and the upgrade of U.S. 90 from Pinhook Road to Broussard which was completed in October 2012 at a cost of $20 million. Frontage roads were constructed along U.S. 90 between LA 675 and LA 88 at a cost of $21.4 million. These were completed in January and June 2011 respectively. Additional frontage roads were added to U.S. 90 from LA 83 to Darnell Road ($5.4 million and finished in February 2012), from Darnell Road to LA 85 ($5.8 million and finished in April 2014) and at Captain Cade Road ($1.4 million and complete in August 2012).

Louisiana: Interstate 49 North

Interstate 49 North is broken into 11 segments at a total cost of $670 million:28

  • 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 was estimated to cost $385 million.9 Work continued in 2007 on Interstate 49 at the state line, where crews completed earth moving on a 6.6-mile long section near the Arkansas state line.

State money was secured to bridge the 20% funding gap needed for I-49 North, 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 later 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 that awaited until Arkansas completed its extension of Arkansas 549 southward, which was 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


Interstate 49 in southwest Arkansas overtook the Arkansas 549 freeway between Exit 4 (U.S. 71) near Doddridge and U.S. 59 & 71 north of McKinney Bayou and Texarkana as well as Future Interstate 130 along Arkansas 245. The first segment of this freeway route (from Fouke to Texarkana) was completed on December 16, 2004.7 The remainder south to Louisiana opened on November 10, 2014.

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 branches northeast to Interstate 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

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 Chaffee, southeast of 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 constructed an interchange at 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 concluded on July 14, 2015.30

Leading north from Fort Smith to the 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 are dually signed as Future I-49 and Arkansas 549.26

What was previously 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 covered 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


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 was 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.

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 then-Future Interstate 49 / U.S. 71 by September 2010. These included those at 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 with a planned completion by 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 opened later in 2012.18

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

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 feasible. One proposal considered is to reroute Interstate 49 northeast along Interstate 310 and end it near the Jefferson Parish line.

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.
