Modot Road Closure Notice

Due to the recent change in river level projections and the 2” to 3” rain in the forecast for Wednesday, we are expecting I-55 be underwater after midnight tonight and may be this way for a day or two.  We will continue to monitor Jeffco Blvd and Telegraph over the next couple days as well.

More Rainfall expected to Close More St. Louis Area Roads:

I-55, Telegraph and Lemay at Meramec River Expected to Close Overnight 

  1. ST.LOUIS – Flood water from area rivers continue to rise and cause more road and highway closures around St. Louis this week. The expected closure that will most impact drivers connects St. Louis County to Jefferson County:
  • I-55 , Route 61/67/Lemay Ferry and Route 231/Telegraph at the Meramec, between St. Louis and Jefferson Counties are expected to close overnight. I-55 is expected to be underwater after midnight. 
  • Late Monday night, I-44 closed in St. Louis County.

Interstate 44 between I-270 in St. Louis County and Route 100/Gray Summit in Franklin County is closed.  It closed earlier than expected due to the Meramec River rising faster than earlier predictions.

  • Westbound I-44 is closed at I-270 while eastbound I-44 is closed at Route 100/Gray Summit.  Local traffic only will be allowed westbound to Bowles and eastbound to Pacific, Eureka and Route 109.  Interstate traffic cannot get through this area.

Route 100 between Gray Summit and I-270 will be the alternate route for I-44 travelers. 

  • Route 30  at Meramec River at St. Clair near I-44 in Franklin County is open. It could relieve for eastbound I-44/ Rte. 100 traffic.

Additional Closures:

  • Route 109 (St. Louis County) from Eureka High School to Route W/FF
  • Route 30/Gravois (St. Louis County) at Meramec River closed early this morning.
  • Route 21/Tesson Ferry (St. Louis County) at Meramec River expected to close today or tonight

Other local closures:

  • Route 67 is reduced to one lane with  traffic from Alton, IL into Missouri between the Mississippi River and Missouri River
  • Route 141 at I-44 in St. Louis County is closed and will remain closed most of the week

Other information:

  • Heavy rains over the weekend still have more than 300 roads across the state.
  • Currently Interstate 44 is closed between Rolla and Lebanon and is not expected to reopen until mid to late week.  Cross state travelers should avoid using I-44 due to the closures in St. Louis and between Rolla and Lebanon. Please use Interstate 70 between St. Louis and Kansas City and then use Interstate 435 to Interstate 49 to Joplin to reconnect to Interstate 44.
  • Most of the major routes are not expected to reopen until late in the week due to rising waters on the major rivers.
  • When the water recedes, MoDOT will inspect the pavement and bridges for safety before opening the roadways for public use.

Missourians should take these precautions in areas affected by flooding.  Never drive past a barricade closing flooded roads. They are there to protect you.  Don’t drive through water.  Turn around, don’t drown.
