GRASS VALLEY – Caltrans is scheduled to resume construction Monday, April 19 on a $27.1 million safety improvement project on State Route 174 between Maple Way and You Bet Road in Nevada County.

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.

Traffic-interfering work will be performed during daylight hours, Monday through Friday between 7 a.m. and 5 p.m. with occasional Saturdays. Reversing one-way traffic control will be 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.

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. The department will issue construction updates on Twitter @CaltransDist3 and on Facebook at CaltransDistrict3. For real-time traffic, click on Caltrans’ QuickMap or download the QuickMap app from the App Store or Google Play.
