A semi crash caused damage to an interstate bridge in Council Bluffs late Thursday afternoon, forcing authorities to shut down an I-29 access ramp.
Police say Dale Shambaugh was crossing over I-480 from Omaha to go northbound on I-29 when te=he tractor-trailer began to tip as it rounded the curve.
Police say at some point either the trailer struck a guardrail causing chunks of concrete to fall onto I‐480 westbound. The tractor trailer was hauling large rolls of steel that unrolled onto the interstate.
Shambaugh was not injured, nor were any other motorists. I‐480 westbound was restricted to one lane for about an hour while the concrete was cleaned up. The ramp from I‐480 east to I‐29 north will remain shut down at least overnight.
Iowa Department of Transportation Motor Vehicle Enforcement is assisting police in the investigation of this crash. Drivers wishing to go northbound from eastbound I‐480 should proceed south on I‐29 to 9th Avenue, pass under I‐29, then turn left onto I‐29 northbound.
