Grass Valley – Caltrans is alerting motorists about various lane closures and night work along State Route 49 (SR 49) in Nevada County for the next several months as work begins on the $124.9 million SR 49 Corridor Improvement Project between Allison Ranch Road/La Barr Meadows Road to the McKnight Way interchange in Grass Valley.
Crews are scheduled to begin tree clearing along SR 49 starting Monday, February 9. Work during the day will take place off the highway along the shoulders and not anticipated to impact traffic. Work during the evenings will include various lane closures with one-way reversing traffic control and a pilot car from 9 p.m. to 6 a.m. during the week and from 8 p.m. to 6 a.m. on Sundays.
The extended lane closures will help to minimize the duration of the work and improve workers’ safety. Nearby residents may hear loud construction noises including backup truck beeping and equipment during nightly operations.
Work will be shared by two teams. One team will start near Crestview Drive and the other team will start near Wellswood Way. Both teams will gradually move south and estimate to complete tree clearing within 1-2 months. Utility relocation will take an additional 2-3 months with the main road work scheduled to begin in June.
The schedule is subject to change or be delayed due to weather, availability of materials or other unexpected events.
Granite Construction, Inc. of Sacramento is the prime contractor for the project, which 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 between Allison Ranch Road/La Barr Meadows Road to the McKnight Way interchange in Grass Valley. An additional southbound truck-climbing lane will be constructed within the project limits along with a new entrance to the Nevada County Transit Operations Center.
The project was funded in part by $7.9 million from Senate Bill (SB) 1, the Road Repair and Accountability Act of 2017.
SB 1 provides $5 billion in transportation funding annually that is shared equally between state and local agencies. Road projects progress through construction phases more quickly based on the availability of SB 1 funds, including projects that are partially funded by SB 1.
