Shawnee Mission Parkway construction in parts of Merriam and Overland Park is set to continue through at least Sept 1.
This construction, which has gotten the busy thoroughfare down to one lane at times, is connected to a water main replacement underneath the stretch of Shawnee Mission Parkway from Antioch Road to Metcalf Avenue.
Heading up the project is the Kansas Department of Transportation, which oversees roadwork on highways like Shawnee Mission Parkway, also known as U.S. 56.
Here’s what drivers can expect between now and Sept. 1, which is the timeline for completion, according to the KanDrive website.
The water main replacement should wrap up in mid-August
- Mandy Cawby, director of customer relations for WaterOne, told the Post via email that the construction currently underway is to replace “5,500 feet of aging infrastructure.”
- This work hits seven street crossings along Shawnee Mission Parkway, Cawby said.
- Cawby said the work is in its final phase and is estimated to be completed by mid-August.
A street resurfacing project will follow
- Cawby said KDOT will start its own mill and overlay, or street resurfacing project, after the main replacement work is completed.
- The back-to-back water main and road projects helps to “minimize cost and disruption” for the community and drivers, she said.
- “Whenever possible, WaterOne strives to prioritize and coordinate our infrastructure projects like this with cities’ and KDOT’s planned road projects,” Cawby said.

What’s next:
- Cawby said drivers can expect lane closures at the intersection of Shawnee Mission Parkway and Antioch Road later this week.
- Shawnee Mission Parkway will be down to one eastbound and one westbound lane, and Antioch Road will go down to one lane southbound lane.
- These closures will last for several days in order “to complete a road crossing replacement,” Cawby said.
- Project updates can be found online here.
