The Porterville Road Bridge over Interstate 15 north of Blackfoot remains closed after a backhoe being hauled by a semi struck the bridge from underneath Tuesday evening, causing severe damage to a girder. The bridge will remain closed until the Idaho Transportation Department can install a temporary traffic light to allow one lane of traffic over the undamaged portion of the overpass.
ITD is still assessing the damage to determine what work will be required to repair the bridge. Motorists are encouraged to check 511.idaho.gov for the latest information on this closure and other traffic events.
