If you're planning to navigate the roads around Pershall Rd. anytime soon, take note that you'll need to adjust your evening commute come the end of July. According to an announcement from the Missouri Department of Transportation (MoDOT), Pershall Rd. will be temporarily out of commission for two nights. Specifically, the stretch between Hanley Rd. and Hazelwood Ave. is set to close.

The closures are scheduled for Monday and Tuesday, and will last from 7 p.m. to 5 a.m. on both nights. The reason? Crews need to safely place girders for the new I-170 bridge that's going to span over Pershall Rd. Motorists are advised to look out for signs that will direct them to detour around the affected areas. And while the intention is to quickly return the road to serviceable use, all this is, of course, dependent on the weather willing to cooperate. To swiftly move through these necessary closures, motorists will hope for clear skies.

The new bridge is part of a broader project to improve St. Louis’s roadways. For two nights, drivers will need to follow detours due to planned closures.

MoDOT says the closures are necessary for the I-170 bridge construction. Drivers are advised to plan ahead, consider alternate routes, and watch for posted signs around Pershall Road to avoid delays.
