Skagit County bridge closed; tipster says something fell off
Update: Skagit County officials say the inspection team finished up just before 9:30 p.m. and didn't find any damage. The bridge will reopen to traffic by 10 p.m.

LA CONNER, Wash. (AP) - A Skagit County bridge in northwest Washington has been closed as a precaution after a tipster reported seeing an object - possibly a piece of concrete - fall from the bottom of the structure and into the channel below.

State Transportation Department investigators have been dispatched to determine whether the so-called Rainbow Bridge near La Conner is sound.

The Skagit Valley Herald reports that county Public Works Director Dan Berentson says public works and sheriff's department employees were unable to confirm whether any piece of the bridge had fallen off.

Berentson says the bridge was closed to traffic shortly after the Thursday afternoon report. Traffic was rerouted.

Skagit County owns the arch bridge, which is painted red, unlike other typically green road bridges in Washington. WSDOT is helping inspect the bridge.

A section of an Interstate 5 bridge over the Skagit River fell into the water on May 23, 2013, after a truck carrying a tall load hit the bridge in Mount Vernon, about 60 miles north of Seattle. Two other vehicles fell into the river; three people were rescued with minor injuries.
