(Manzanita, OR) -- Highway 101 will remain one lane with flaggers north of Manzanita through September because of damage to a bridge. The Oregon Department of Transportation says repair work on the Necarney Creek Bridge won't begin until late this month. A section of sidewalk and guardrail broke off late last month. The Oregon Department of Transportation says it appears it was hit by a vehicle, but there were no reports of a crash. With only one lane open, traffic is being flagged at the bridge around-the-clock. Drivers should expect long delays.
