Placer County - Caltrans is reminding motorists of various lane and ramp closures in multiple locations along State Route 49 (SR 49) as several projects continue in Placer County.
Here is the breakdown for next week:
American River Canyon Roundabout Project
- SR 49 remains closed between the intersection with Lincoln Way/Borland Avenue and the American River Confluence. Motorists traveling between Auburn and Cool will detour using Foresthill Road and Old Foresthill Road. SR 49 is scheduled to reopen in the new roundabout configuration by 6 a.m. Monday, December 22.
Sidewalk Gap Closure Project
- Southbound between Dry Creek Road and Bell Road, various lane closures are scheduled for drainage work from 7 p.m. to 7 a.m. Sunday, December 14 through Thursday, December 18. Work is scheduled to end for the week by 7 a.m. Friday, December 19.
- Southbound between Luther Road and Edgewood Road, various lane closures are scheduled for utility work from 10 p.m. Sunday, December 14 to 6:30 a.m. Monday, December 15 and from 8 p.m. to 6:30 a.m. Monday, December 15 through Thursday, December 18. Work is scheduled to end for the week by 6:30 a.m. Friday, December 19.
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.
