Caltrans is alerting mototists of a change in construction schedule for a State Route 174 (SR-174) safety improvement project between You Bet Road and Greenhorn Access Road in Nevada County. 

Beginning Wednesday, July 7one-way traffic control will be in effect around the clock for construction work. While construction activities will still be restricted to daytime hours between 6 a.m. and 7 p.m., highway widening work throughout the entire project limits requires 24/7 traffic control. The existing highway is not currently wide enough to accommodate two-lanes of traffic while the roadway is widened further. Motorists are advised to anticipate 20-minute delays when passing through the construction zone area. Around-the-clock one-way traffic control is expected to be in effect through July 28.

The $27.1 million safety 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.

Flaggers at each end of the construction zone will be utilized along with a pilot car. 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.

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. For real-time traffic, click on Caltrans’ QuickMap or download the QuickMap app from the App Store or Google Play.
