State Route 49 Construction Update for Gold Country Corridor

Various Lane Closures Scheduled Between I-80 and Placer/Nevada County Line

PLACER COUNTY – Caltrans is reminding motorists of various lane closures in multiple locations along State Route 49 (SR 49) as several improvement projects continue in Placer County. 

Here is the breakdown for next week:

Safety Barrier Project

• Extended lane reduction at Lone Star Road, intersection scheduled to return to normal operations with the new roundabout configuration in place by 3 p.m. Monday, September 8.
• Northbound between Lorenson Road/Florence Lane and Lone Star Road, various lane closures are scheduled from 9 a.m. to 3 p.m. Monday, September 8 through Friday, September 12 and from 7 p.m. to 7 a.m. Monday, September 8 through Thursday, September 11. 
• Southbound between Lone Star Road and Lorenson Road/Florence Lane, various lane closures are scheduled from 7 a.m. to 5 p.m. Monday, September 8 through Friday, September 12 and from 7 p.m. to 7 a.m. Monday, September 8 through Thursday, September 11.
• Final extended lane reduction at Lone Star Road
• Crews will reduce northbound and southbound SR 49 to one lane in each direction from 6 a.m. Friday, September 12 through 3 p.m. Monday, September 15.
• Movement around the roundabout will be limited at various times and only allow right-hand turns onto SR 49. Motorists will need to detour northbound or southbound to the next legal U-turn as needed.

Sidewalk Gap Closure Project

The extended lane closures will help to minimize the duration of the work and improve workers’ safety. Motorists may experience delays between 15 to 20 minutes, depending on traffic volumes. The schedule is subject to change or be delayed due to weather, availability of materials or other unexpected events.
