Construction Details

Project construction began in April 2026.

Interstate Lane Shifts and Speed Reductions

  • At least two interstate lanes will remain open in each direction during daytime hours.

  • Interstate lanes will be reduced to one lane in each direction during nighttime hours.

  • Traffic shifts and crossovers will take place, routing traffic around areas of active bridge demolition and reconstruction.

  • Interstate speed limits will be reduced to 55MPH in work zones.

  • Intermittent side street and brief interstate detours will take place as individual sections of bridge are removed. Advance notice will be given, and daytime traffic will still be able to utilize interstate lanes.

  • Interstate drivers can anticipate moderate travel delays through the work zone.

  • Construction schedule is weather permitting and subject to change.

Construction Update: September 2026

Crews are busy building a portion of the new bridge structures in the median or inside of the interstate at the Mae Anne, 4th Street/Lawton, and Mogul locations. Current activities include limited demolition, minor earthwork, and construction of new abutments.

​

Once these new sections are completed, traffic will be crossed over to the westbound side of the interstate for full demolition and construction of the eastbound structures. Two lanes of travel will remain open in each direction. This next phase is expected to occur in spring 2027.

​

At the Garson bridge site, construction of piers and columns are underway for a portion of the new structure. Once the new structure is built, demolition of the existing structure will begin. Access to businesses will remain available with minor detours.

​

Current traffic control:

  • Traffic is shifted to the outside lanes of the interstate.

  • Two lanes are open in each direction during daytime hours.

  • Speed limit is reduced to 55 MPH.

 ​

Local roads:

​Traffic is reduced to a single lane during daytime hours (7am-7pm) on Mae Anne Avenue, West Fourth Street and Mogul Road underneath I-80. Traffic flaggers will alternate directions of travel, with minor travel delays.
