I-70 Travelers: Expect Daily Delays near Boonville Starting July 12

Travel Tools Available to Help

Lamine River Bridge The bridges that carry Interstate 70 over the Lamine River near Boonville are due to get new driving surfaces and other repairs, work that will require closing one bridge at a time resulting in single-lane, head-to-head traffic on I-70 beginning July 12.

The bridge closures are expected to cause significant travel delays, especially on Thursdays, Fridays and Sundays - peak travel days. Traffic studies show westbound traffic will be impacted more than eastbound, due in part to more traffic traveling west and the steeper road grade in the westbound lanes.

MoDOT officials are strongly encouraging I-70 motorists to use alternate east-west routes, such as U.S. Routes 50 and 36, while the project is in progress. (MORE)

Independence Day Travelers Reminded of Missouri River Bridge Closure


Travelers taking to the roads to celebrate the Fourth of July holiday are reminded that just one bridge is carrying both directions of Route 54/63 traffic over the Missouri River in Jefferson City causing some traffic delays during peak travel times.

The westbound bridge closed on May 1 for repainting and general maintenance, and traffic is diverted to the eastbound bridge. The westbound bridge is scheduled to reopen by the end of August.

MRB traffic switch

In addition to the bridge closure, the following access ramps are closed:

  • All access ramps from Route 54/63 to and from West Main Street;
  • The eastbound on-ramp from McCarty St. to Route 54/63; and
  • The westbound on-ramp from Route W to Route 54/63.
