(Onawa) The Iowa Department of Transportation’s Sioux City construction office says the Iowa 175 bridge over I-29 was hit earlier today by an oversized, overweight load. The Iowa DOT has the Iowa 175 bridge as well as portions of I-29 in the area closed while we perform an inspection and cleanup work associated with the bridge hit.
Once the inspection and associated work is complete, Iowa 175 over I-29 will be down to a single lane of alternating traffic using a temporary signal. The timing of this is currently unknown.
This structure has been hit before and is posted for low clearance. Repairs have been made previously as well. The structure is anticipated to be replaced in 2026.
