Inspection of Interstate 40 Mississippi River Bridge to Cause Lane Closures


An inspection of the Interstate 40 Mississippi River Bridge will require single outside lane closures for several days through mid-March.   This hands-on inspection will be performed by ARDOT’s consultant, HNTB. 

ARDOT crews will also utilize these planned lane closures to conduct a hands-on evaluation of the repair work completed last summer on the tie girders of the main arch spans.

Weather permitting; Monday, February 28, outside lane closures will begin in the westbound direction and continue for eight days, including weekends. Once the westbound direction is complete, crews will close the eastbound outside lane for approximately eight days. Only one lane of traffic in one direction will be closed at a time, and will be limited to the following times:

  • Westbound outside: Mon-Fri | 5:30a.m. – 3:30p.m.
  • Eastbound outside: Mon-Fri | 8:30a.m. – 6:30p.m.
  • Either WB or EB outside: Sat-Sun | 7a.m. – 5p.m.

The next phase of inspection for this bridge will occur this summer, where the consultant will perform additional ultrasonic testing of steel welds within the five spans west of the main arch.   A full inspection of the main arch spans is scheduled for September 2022.
