KING COUNTY, Wash. — New sensors are in place on the White River Bridge to let drivers know if their vehicle is too tall to travel through.

Crews finished testing the new technology on Friday.

If your vehicle is too tall, the system will activate warning signs, flashing beacons, and audible alarms before you reach the bridge, telling you to turn around.

Last year, an over-height semi-truck hit the bridge on State Route 410, causing serious damage.

No one was hurt, but it caused a two-month closure, making travel between Enumclaw and Buckley very difficult. The detour spanned about 35 miles.

Damages were estimated to be around $6 million. According to the Washington State Department of Transportation (WSDOT), 10 critical components were damaged.
