Upcoming Road Construction Projects

As the weather improves, more road crews will be out on construction projects this spring and summer. In Maryland Heights, there are three main entities that maintain our roadways: MODOT (who maintain highways and other state routes), St. Louis County Transportation (who maintains several of our main roads), and the City of Maryland Heights Public Works Department (who maintains city streets). To view a map of who maintains which roads, visit www.marylandheights.com/streetmaps.

We've compiled a list of the projects that will be happening this summer, and a few that are just on the horizon in the design phase so you can stay alert, drive safely, and be updated with the most current news! 

Maryland Heights
Adie Road (Dorsett Rd. to Lindbergh Blvd.)

Adie Road is about to get a makeover! This project involves the reconstruction of this section of Adie with the addition of sidewalks constructed to Grand Circle Drive on the western/northern side. This will include the replacement of the box culvert, which sits under the road, during which Adie Road will be closed (April 1 - mid August) to all through traffic. After the box culvert replacement, the street will be constructed one-half mile at a time with traffic restricted to one lane from Dorsett to Lindbergh (August - October).

Construction is expected to be completed by fall 2024. 

St. Louis County
Westport Plaza Dr./ Marine Ave.
Work continues with this resurfacing project, which is bringing curb repairs, ADA-compliant curb ramps, sidewalk repairs, and Accessible Pedestrian Signal upgrades at traffic signals and traffic signal replacements. 

Construction is expected to be completed by summer 2024. 

McKelvey, Bennington, Ameling, and McKelvey Phase II
Both of these projects provide pavement resurfacing and the addition of ADA-compliant curb ramps and sidewalks. Once completed, pedestrian accessibility will be vastly improved. St. Louis County states that they are waiting for consistently warmer weather to finish the paving operations.

Construction is expected to be completed by spring 2024.

McKelvey (Creve Coeur Mill to Natural Bridge) and Creve Coeur Mill (Prichard Farm to Interstate Dr.)
These two resurfacing projects will include pavement resurfacing, concrete pavement repairs, curb ramps, sidewalk replacements, and traffic signal upgrades. St. Louis County will be hiring a contractor late this summer. 

Construction will begin towards the end of 2024.

Prichard Farm Bridge
St. Louis County has been actively working with the levee district to coordinate mutually agreed repairs to the damage that took place in the June 2022 flooding event. They currently do not have a schedule for re-opening the road at this time. 

No construction timeline has been set.
