A low bridge in Council Bluffs is proving challenging to motorists.
Drivers of tall vehicles have hit the train bridge twice this week and at least five times this year.
Pat Miller, of the Council Bluffs Public Works Department says motorists don't realize their vehicles won't fit under the 8-foot 8-inch bridge.
New signs and flashing lights have helped, but people still smash into the span, owned by Canadian National Railroad.
Last week, George Weber of South China, Maine, took off his RV's air conditioning unit, causing about $2,000 damage to his vehicle. He told officers he didn't realize the RV was so tall.
Council Bluffs Police Traffic Division Sgt. Jason Bailey says the bridge rarely suffers damage. He notes, "usually the vehicles lose that one."
