Workers put up road signs Monday, one of the finishing touches to a road project at Highway 108 and Fifth Avenue in Jamestown that also includes adding a stoplight.

The project 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.

Funding for the $3.4 million project came from traffic impact mitigation fees 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.
