# Missouri road construction disruptions > Live situation record from CLSTR: https://clstr.news/situations/missouri-road-construction-disruptions > Updated: 2026-09-03T14:45:48.000Z. Sources: 9. Developments: 5. In July 2026, MoDOT announced an 11-month closure of Interstate 70 through downtown Kansas City for 2027, providing alternate routes including I-435 and I-35. Later that month, the agency issued safety alerts for seasonal mowing crews and detailed detours for oversized trucks on I-55 near Cape Girardeau due to damaged concrete curbs. In August 2026, MoDOT expanded its maintenance schedule. For the week of Aug. 10-16, projects include resurfacing Route J in Andrew County, Highway 136 in Atchison County, and bridge work on Highway 36 in Caldwell County involving lane reductions and flagger control. On I-70, eastbound traffic will shift to a newly paved median, narrowing lanes to 10 feet and reducing the speed limit to 55 mph, with limited access at exits 144 and 148. Other disruptions include the reopening of the St. Charles Road Bridge and bridge-deck replacement on Route H west of Fulton. New projects scheduled for late August include the closure of Route Z near Gordonville to replace bridges over Hubble Creek and Hubble Creek Overflow. This $3.38 million project, involving Robertson Contractors, Inc., aims to install wider structures and raise the roadway to prevent flooding, with an estimated completion of September 1, 2027. Additionally, Route 34 will be reduced to one lane for bridge and pavement work between Route 72 and County Road 302. In McCracken County, overnight detours are planned for I-24 at Exit 7 on August 15-16 to accommodate median drilling by Lumos Fiber. In early September 2026, MoDOT and the Missouri State Highway Patrol issued advisories for upcoming work. To accommodate holiday traffic, most construction activity will be suspended from noon on Friday, Sept. 4, until 6 a.m. on Tuesday, Sept. 8. Scheduled projects for the week of Sept. ## Timeline ### 2026-09-03: Missouri highway construction and maintenance projects cause traffic warnings Missouri officials are warning motorists of traffic delays due to highway maintenance in North Missouri and ongoing expansion projects on Interstate 70, especially during football game days. 2 sources. https://clstr.news/cluster/missouri-highway-construction-and-maintenance-projects-cause-traffic-warnings ### 2026-08-13: Missouri roadwork to impact Route Z, Route 34, and I-24 Major construction projects in Missouri will impact Route Z, Route 34, and I-24, including a long-term bridge replacement on Route Z scheduled to conclude in September 2027. 3 sources. https://clstr.news/cluster/missouri-roadwork-to-impact-route-z-route-34-and-i-24 ### 2026-08-07: Missouri DOT announces extensive road closures across the state MoDOT announced extensive road work and lane reductions across Missouri, including I‑70 traffic shifts in Boone and Callaway counties and bridge maintenance, with closures lasting into 2027. 4 sources. https://clstr.news/cluster/missouri-dot-announces-extensive-road-closures-across-the-state ### 2026-07-28: MoDOT warns drivers of mowing crew hazards and oversized truck detours on Missouri highways MoDOT cautions drivers about mowing crews and rerouted oversized trucks on I‑55, which have damaged roundabout curbs and led to detour adjustments through 2027. 2 sources. https://clstr.news/cluster/modot-warns-drivers-of-mowing-crew-hazards-and-oversized-truck-detours-on-missouri-highways ### 2026-07-15: Missouri DOT Announces 11‑Month I‑70 Closure in Kansas City for 2027 Missouri DOT will close I‑70 through downtown Kansas City from Jan‑Dec 2027, urging drivers to use alternate interstates such as I‑435, I‑35 and US‑71 and follow detour maps. 2 sources. https://clstr.news/cluster/missouri-dot-announces-11month-i70-closure-in-kansas-city-for-2027 --- Cite as: Missouri road construction disruptions.
