Highway 101 will be closed in both directions this weekend to repair the Necarney Creek Bridge.
A section of the sidewalk and railing fell off when it was apparently hit by a vehicle. The bridge is located between Manzanita and Cannon Beach at milepost 39.
The closure will start at 7 o'clock Saturday morning and continue through 7 o'clock Sunday evening.
Detour routes include Highway 53 to Highway 26, or Highway 101 to Highway 6. The emergency repairs will allow both lanes of the bridge to reopen.
Currently, one-way traffic is being flagged over the bridge.
