Hazelwood drivers are getting an early warning: some of the region’s busiest highways are in for a serious shake-up in 2026.
On Thursday, the Hazelwood City Council heard from MoDOT’s North Area Engineer about a packed slate of upcoming road projects that could temporarily scramble commutes and local deliveries. A color-coded map laid out where crews plan to resurface pavement, add lanes and tackle bridge work along I-70, I-270 and Lindbergh (Route 67). Council members were told to expect lane shifts, overnight closures and multi-phase bridge work that will play out in stages around the city.
Projects that will touch Hazelwood
The MoDOT map highlights several specific projects expected to hit Hazelwood-area traffic. Those include I-70 pavement resurfacing from west of Airflight Drive to Route 115 (Natural Bridge); pavement resurfacing combined with ADA pedestrian upgrades on Route 67 (Lindbergh) from Route 367 to Route AC; and an I-270 corridor effort that will add lanes and replace bridges from Lilac Avenue to west of Route H (Riverview). The PDF also flags related work such as median barrier replacement, signal upgrades and repairs to pedestrian facilities, with many of these items marked for 2026 construction. These details are drawn from MoDOT.
Part of a bigger push across St. Louis County
According to local reporting and recent MoDOT briefings, the north-county work is one slice of a much larger construction push across the St. Louis region. Roughly $1.7 billion in local projects is on the books, with the Improve I-70 program standing out as one of the largest efforts. Crews are expected to rely on phased work windows, overnight lane shifts and targeted ramp closures in an attempt to keep traffic moving while major resurfacing and bridge jobs roll ahead, Spectrum News reported.
What officials told council and where to get details
Tabitha Locke, who is identified as MoDOT’s North Area Engineer on the agency’s North St. Louis County leadership page, was cited in connection with the briefing to Hazelwood officials. After the meeting, the city shared the construction map and a short summary on its official Facebook page so residents could see the same information council members received. For project pages and contact information, residents are directed to MoDOT, and can review the shared map in the City of Hazelwood post.
Commuter tips
Drivers in and around Hazelwood should expect some short-term pain in exchange for fresh pavement and upgraded bridges. Officials recommend planning extra travel time on active work days, watching for posted detour signs and being ready for occasional overnight closures. The city’s Facebook updates and MoDOT’s project pages will carry public meeting dates and schedule changes as the 2026 construction timeline gets locked in.
