(Radio Iowa) – A highway bridge over Interstate 29 near Onawa is being closed today (Thursday) for emergency repairs and is currently scheduled to reopen August 5th. Sarah Tracy, an Iowa D-O-T transportation planner based in Sioux City, says the Highway 175 bridge has been hit three times since April.

“It’s been vehicles that are too high and they’re hitting underneath the bridge,” Tracy says. There may be some lane closures on I-29 as crews work on the bridge over the interstate and there’s a work zone on I-29 in the Onawa area that requires drivers to reduce their speed to 55 miles an hour.

The D-O-T has set up a marked detour route for drivers who would otherwise use the Highway 175 bridge.
