For Immediate Release

GRASS VALLEY – Caltrans is alerting motorists of planned construction work this Saturday on State Route 174 (SR-174) between You Bet Road and Greenhorn Access Road in Nevada County. 

Motorists may expect one-way traffic control from 6 a.m. to 7 p.m. Saturday in preparation for anticipated shoulder widening and paving work next week on the $27.1 million safety improvement project. Following the completion of this work, a traffic lane shift is tentatively scheduled May 21 between Quail Point Lane and You Bet Road. Traffic will be temporarily shifted to the west side of the existing roadway. The move will allow crews to work safely on the east side of the highway. Motorists should also be aware that lanes will be slightly narrower during this temporary transition. 

Traffic-interfering work for the project continues to be performed during daylight hours, Monday through Friday between 6 a.m. and 7 p.m. with occasional Saturdays. Reversing one-way traffic control is being used to manage traffic with 20-minute delays anticipated.

Motorists are reminded that pilot vehicles are to be followed at all times within the project zone for the safety of construction crews and travelers. Failure to follow pilot vehicles may result in a $220 citation with traffic fees doubled in construction zones. The California Highway Patrol will be on site, monitoring traffic safety during construction.

The project, which began in August 2020, is realigning several curves, widening shoulders, adding a southbound left-turn pocket at Greenhorn Access Road and improving the clear recovery zone for errant vehicles to regain control. DeSilva Gates Construction of Sacramento is the primary contractor for the project and completion is anticipated this fall.

Weather or unexpected events may delay or prolong the work. Caltrans advises motorists to “Be Work Zone Alert.” The department will issue construction updates on Twitter @CaltransDist3 and on Facebook at CaltransDistrict3.
