Harrison County Route A to close for a bridge project

I-35 will also be impacted

ST. JOSEPH, Mo. – The Missouri Department of Transportation (MoDOT) is reminding motorists impacts on Harrison County Route A and I-35 at Exit 99, which will begin Monday, May 16.

A bridge rehabilitation project will close Harrison County Route A, beginning Monday, May 16, and continue through September 2022. The project, led by contractors from Emery Sapp & Sons, Inc., working with the Missouri Department of Transportation, will replace the deck of the Route A bridge over Interstate 35 at Exit 99, between Bethany and Eagleville and will impact traffic on both Route A and I-35.

Interstate impacts:

  • May 16 – 20, 9 p.m. to 6 a.m. daily: I-35 under the bridge will be closed in both directions
    • Interstate traffic will be directed up and over the on/off ramps at the exit during the overnight hours. Motorists could experience delays and may wish to use an alternate route.
  • May 20 through September 2022: I-35 may be narrowed to one lane through the project work zone with a 12-foot width restriction.

Route A impacts:

  • May 16 – September 2022: bridge over I-35 closed to all traffic
  • May 16 – 20, 9 p.m. to 6 a.m. daily: ramps closed. No access to I-35 from Route A, any direction, during overnight hours
  • Saturday, May 21 through September 2022: ramps to I-35 open, bridge closed
    • Traffic will be detoured on I-35 to the next exit
      • Example: Westbound traffic on Route A wanting to go south on I-35 will use the ramps to go north on I-35 to Exit 106, cross the interstate in Eagleville, and head back south on I-35

All work is weather-permitting, and schedules are subject to change.
