U.S. 54 overpass in Kingdom City to close for demolition in late October

JEFFERSON CITY, Mo. - U.S. Route 54 over Interstate 70 in Kingdom City is set to close in late October for the old U.S. 54 bridges over I-70 to be demolished. During this weekend-long closure, I-70 will be narrowed to one lane and backups are anticipated.

From 7 p.m. on Oct. 30, 2026, to 5 a.m. on Nov. 2, 2026, construction crews working with the Missouri Department of Transportation plan to demolish and remove the two no-longer-used bridges in the middle of the new roundabout at I-70 and U.S. 54. For the safety of the crews and motorists, the roundabout will be closed, and there will be no access over I-70 via U.S. 54. The ramps at Exit 148 will remain open.

During the demolition the traffic impacts will be as follows:

• I-70: Both directions of I-70 will narrow to one lane and drivers will be directed up and over the ramps at Exit 148 (U.S. 54) and back onto I-70.

• S. 54: While the ramps will remain open, traffic on U.S. 54 will not have access across I-70.
  • Eastbound U.S. 54 traffic will be detoured via eastbound I-70 to Callaway County Routes A/Z (Exit 155) to westbound I-70.
  • Westbound U.S. 54 traffic will be detoured via westbound I-70 to Callaway County Route M (Exit 144) to eastbound I-70.
    • All ramps at Route M/Hatton will be open for the duration of the demolition. After the demolition is complete, the eastbound ramps will close again.

Once the demolition and cleanup are complete on Monday morning, Nov. 2, I-70 and U.S. 54 will return to the current traffic pattern.

Motorists are advised to plan extra travel time as backups are anticipated.

All work is weather-permitting and subject to change.

MoDOT asks all motorists to work with us by buckling up, putting your phone down, obeying all traffic signs, and slowing down and moving over in work zones.

This work is part of one project in MoDOT's Statewide Improve I-70 Program, Improve I-70: Rocheport to Columbia, which will add a third lane of travel in each direction to the 14-mile stretch of I-70 between the Missouri River Bridge at Rocheport and approximately U.S. Route 63 in Columbia. This $441 million fixed-cost contract includes new pavement on all three lanes of I-70 and will also make interchange improvements at Route J/O, Midway (Route 40), Stadium Blvd., Business Loop 70, Providence Rd., Rangeline St., and U.S. Route 63.

Missouri's FY2024 budget, approved through the state legislative process and governor, provides $2.8 billion in General Revenue to build a third lane of I-70 across the state. The program will plan, design, construct, reconstruct, rehabilitate, and add a third lane in each direction on nearly 200 miles of I-70, from Blue Springs to Wentzville.
