The temporary traffic signal on U.S. Highway 101's Klamath River bridge has been removed as work to replace the structure's hinges takes a break until next year.

A similar traffic signal at Last Chance Grade has also been removed, but motorists will still be subject to one-way traffic from 7 a.m. to 7 p.m. weekdays until work on the guardrail is complete, said Caltrans spokesman Scott Burger.

Flaggers will man the area and motorists should expect delays of 10 minutes during work hours, Burger said. Work on the guardrail is expected to be finished by Nov. 1, he said.

"The project is basically done. This is just the icing on the cake," Burger said, adding that the striping of the road was just finished. "The paving and all the major work is done."

Motorists traveling between Crescent City and Klamath have experienced one-way signal-controlled traffic for about a year while Caltrans workers repaired and strengthened a retaining wall.

During the summer, signals on the G.H. Memorial Bridge farther south reduced traffic to one lane for work to replace three hinges to extend the bridge's surface life. A hinge is a vital part of a bridge that allows it to expand and contract with changes in the temperature, according to Burger.

The temporary traffic signal will return next year. The project will continue during the 2014 construction season, from June to late October.
