Crews are currently working to stabilize and prepare to remove the overhead sign structure on the Kootenai River Bridge just north of Bonners Ferry this evening after it appears to have been struck by a vehicle.
The steel sign structure, which is estimated to weigh approximately 10,000 pounds, remains bolted in place next to the northbound lanes, but the post near the southbound lanes has become detached. The sign structure remains upright but could be blown over by strong winds.
Crews are on site, ready to close the bridge to traffic if necessary. ITD has contracted a private company to remove the sign with a crane, which is expected to arrive in the next few hours. All lanes will be closed during removal of the sign structure. However, the bridge may close even earlier if strong winds threaten the stability of the damaged sign structure.
During the removal of the sign, all lanes will be closed. Travelers should expect other traffic impacts while crews set up the crane, remove the sign and disassemble the sign and the crane.
Please exercise caution in the area as ITD adjusts traffic flow while addressing this safety issue.
