MoDOT Ready for Main Street Bridge Project

Post Date:03/13/2017 1:16 PM

It’s inconvenient. It’s messy. It’s unavoidable. Such is the price of progress.

MoDOT is set to start construction on a new Main Street Bridge the week of March 27, this while MoDOT crews are still at work on a new 155th Street Bridge and interchange.

The current Main Street Bridge is 60 years old and has reached the end of its useful life. The new Main Street Bridge will be nearly 20 feet wider with barrier sidewalks on both sides for pedestrians. When finished, the bridge will be emblazoned with the words “Grandview” and “Main Street” stamped into the concrete of the bridge.

Expect a ribbon cutting toward the end of the year before the bridge is officially opened to traffic.

The project will cause some issues. On top of backup, drivers can expect reduced lanes on Main Street and no left turns onto Main Street from one of the frontage roads.

The Main Street Bridge will NOT shut down during construction; however traffic will be reduced to two lanes. Crews will shut down one side of the bridge for construction while the other side remains open to traffic. When construction on one side is complete, workers will flip-flop traffic and work zones. That is expected to happen in mid-summer.

Expect some serious back up at Main Street and the southbound Frontage Road because NO LEFT TURNS will be allowed onto Main Street. Drivers will have to follow the posted detours, or get creative. MoDOT Project Manager Brandon Cracraft says left turns from the northbound Frontage Road onto Main Street will be allowed “unless it starts to become an issue.” Drivers will still be able to make left turns from Main Street onto the Frontage Roads.

I-49 will also be affected by the project. I-49 North will lose the inside lane for the duration of the project. There will only be temporary lane drops on I-49 South to accommodate construction. Cracraft is hopeful crews at the 155th Street Project will be in a position to return the third lane to both directions of I-49 by the time crews on Main Street start working. If not, the third lane will be closed from just before 155th Street to just past the Main Street exit.

Most of the work will be done during the day, with some of the heavier demo work being done at night.

For drivers who need to make a left turn onto Main from the frontage roads, consider these detours in addition to the ones MoDOT will have posted:

 main street detour map final final

From the West Frontage Road turn right onto Goode then left on 15th street which will take you to Main Street stoplight.   

If left turns from the East Frontage Road become an issue, MoDOT will provide a posted detour.
