A new stoplight at Highway 108 and Fifth Avenue in Jamestown is expected to be turned within about a week, according to Tuolumne County officials.

Tanya Allen, supervising engineer for the county, said the mast arms and lights were recently installed and they were expecting Caltrans’ electrical group to provide power to the lights as early as Wednesday afternoon.

Allen estimated that it could be about a week before the stoplight becomes operational because they have to do testing after the power is provided.

The project also involved widening Fifth Avenue by 32 feet, adding turn lanes on Fifth Avenue and right-turn pockets on Highway 108, and modifying the alignment of Jamestown Road and Fifth Avenue.

Most of the other work around the intersection is now complete, with the contractor working on some minor erosion issues around inlets.

The $3.4 million project was expected to be completed in December, but there were some delays having to do with the delivery of the mast arms and getting power to the light. Allen said the delay did not cost the county any additional money.

Funding for the project came from traffic impact mitigation fees that the county has collected over the years.

A traffic study in 2012 identified the need for the signal at the intersection, which has received a failing grade from Caltrans due to traffic congestion and accidents.

Caltrans also required a stoplight at the intersection before the county can proceed on a separate project to replace the century-old, one-lane bridge crossing Woods Creek on Rawhide Road.
