The Louisiana Department of Transportation and Development has announced the start of construction for the major I-20 rehabilitation project in Bossier and Caddo Parishes.


Work began on Monday, September 18, 2023, with lane closures put into place in both the eastbound and westbound directions on I-20 from near Hamilton Road to Industrial Drive (LA 782-2) in Bossier City.


This section of the interstate - which services approximately 70,000 to 100,000 vehicles per day - will be fully re-constructed, with all existing pavement and roadway base removed and replaced with new base and concrete. This is a critical improvement for the interstate system in the NWLA region, as this project is removing and replacing original pavement from the 1960s when I-20 was constructed.


This portion of the project is organized into three Phases. A general overview of the construction phasing is as follows:


-     Phase 1):

o   Right lane closed in both directions to allow for construction of temporary diversion pavement on outside shoulder in order to handle traffic load.

o   Approximately 2 months

-     Phase 2):

o   Left lane closed in both directions to allow for construction of new inside lane & shoulder. This phase also includes reconstruction of one or more interchanges. 

o   Approximately 11 months


-     Phase 3):

o   Right lane closed in both directions to allow for construction of new outside lane & shoulder. This phase also includes the reconstruction of one or more interchanges. No two interchanges that are located next to each other will be closed at the same time. 

o   Approximately one year


In addition to the re-construction work, extensive concrete pavement repairs will be underway from Pines Road to Market Street on the west end of the project in Shreveport, and from Industrial Drive to I-220 on the east end in Bossier City. This work will be performed primarily at night in an effort to minimize travel inconveniences in conjunction with the long-term rehab work lane closures.


An innovative traffic management system has been implemented for this project that informs motorists in real time of changing conditions ahead, such as slowing/stopped traffic or an alert to use an alternate route through the use of digital message signs.


All through traffic on I-20 is asked to utilize I-220 as an alternate route to avoid delays in the construction zone.


Additionally, as of December 21, 2023, all commercial motor vehicles (CMVs) such as 18-wheelers are prohibited from driving through the work zone due to narrow lane widths, under Louisiana Revised Statute 32:237. These vehicles are required to utilize the I-220 detour. 


The entire project is anticipated to be complete in early 2026, with progress dependent on weather conditions and other factors that can impact construction timelines.


Anyone interested in receiving email updates on the project is urged to sign up for MyDOTD. The sign-up page for a MyDOTD account can be accessed at this link.


DOTD also offers the ability to track traffic conditions in real time through the Louisiana 511 mobile app and www.511la.org, which also provides access to the live-streaming traffic cameras. We encourage everyone to download the app or check the website prior to traveling in order to plan any alternate routes.


Construction work can be disruptive and inconvenient. We are asking for all drivers to please be cautious and patient as we work through the construction process. We believe motorists will be extremely pleased with the finished product, which will serve Louisiana residents and visitors for many years to come.


Questions regarding damage to personal property that occurs within the construction zone should be directed to JB James Construction at (225) 953-2228.


Current construction activities (Week of January 19, 2026):


  • Project is currently in Phase 3 (final phase) of construction for both eastbound and westbound directions of travel. 

  • The Industrial Drive interchange is now fully back OPEN to traffic following a full reconstruction. ALL ramps have been reopened.

  • The Old Minden Road interchange is now fully back OPEN to traffic following a full reconstruction. ALL ramps have been reopened.  

  • The Airline Drive interchange is now fully back OPEN to traffic following a full reconstruction. ALL ramps have been reopened.

  • Both Barksdale Blvd ramps are now fully OPEN to traffic following their full reconstruction.

  • The I-20 westbound on-ramp from Benton Road is now fully OPEN to traffic following its full reconstruction. 

  • The I-20 eastbound off-ramp to Benton Road is now OPEN following the full reconstruction of the roadway approaches to the flyover bridge. 

  • Concrete paving operations are substantially complete on all travel lanes and ramps. 

  • Short-duration, intermittent lane closures will be necessary after the start of 2026 to allow for final construction activities to take place safely and efficiently. These activities involve electrical work, street lighting, signage installation, seeding, and permanent roadway striping.

  • Project is currently approximately 99% complete.
