Grass Valley – Caltrans is alerting motorists about lane closures and night work along State Route 49 (SR 49) in Nevada County for the next several months. Work is part of the $124.9 million SR 49 Corridor Improvement Project, spanning Allison Ranch Road/La Barr Meadows Road to the McKnight Way interchange in Grass Valley.
Tree clearing along SR 49 begins Monday, February 9. Daytime work occurs off the highway along the shoulders with no anticipated traffic impacts. Evening work will include lane closures with one-way reversing traffic control and a pilot car from 9 p.m. to 6 a.m. during weekdays and 8 p.m. to 6 a.m. on Sundays.
Extended lane closures help minimize project duration and improve worker safety. Nearby residents may hear loud construction noises, including backup truck beeps and equipment during nightly operations.
Two teams will share the work: one near Crestview Drive and the other near Wellswood Way. Teams will gradually move south, completing tree clearing within 1–2 months. Utility relocation will take an additional 2–3 months, with main road work scheduled to begin in June. Schedule is subject to change due to weather, materials availability, or other unexpected events.
Granite Construction, Inc. of Sacramento is the prime contractor. The project is expected to be completed by the end of 2028.
Upcoming work includes constructing a two-way left-turn lane, right-turn lanes, 10-foot shoulders, and a northbound slow-moving truck lane along SR 49. Additional southbound truck-climbing lanes and a new entrance to the Nevada County Transit Operations Center will also be constructed.
The project is partially funded by $7.9 million from Senate Bill (SB) 1, the Road Repair and Accountability Act of 2017, which provides $5 billion annually for transportation projects. Learn more about statewide infrastructure projects at build.ca.gov.
Caltrans District 3 maintains 4,385 lane miles across 11 Sacramento Valley and Northern Sierra counties. Drivers are reminded to “Be Work Zone Alert” and slow in construction zones for safety.
