U.S. Highway 101 over the Klamath River will be fully closed overnight from 10 p.m. Sunday to 4 a.m. Monday, according to Caltrans.

The closure is part of the construction for the Klamath River Hinge Project on the Klamath River Bridge, also known as the G.H. Douglas Memorial Bridge.

Caltrans said that a second full nighttime closure may be necessary from 10 p.m. Monday to 4 a.m. Tuesday if construction is not finished the first night. If the second closure is necessary, electronic signs on Highway 101 will make motorists aware beginning Monday morning.

The project is replacing three hinges on the Klamath River Bridge in order to extend the service life of the structure. Hinges are a vital part of the bridge, allowing it to expand and contract with changing temperatures.

A temporary traffic signal for one-way traffic will remain in place through late October, and motorists should anticipate 10-minute delays.

The Klamath River Hinge Project will resume during the 2014 construction season, from June to late October.
