Highway 49 Placer County Rehabilitation Project

Highway 49 Rehabilitation Project Construction Update

Sunday through Saturday, September 27 – October 3, 2020


State Route 49 (Placer County) from the I-80/SR 49 interchange to Dry Creek Road: Construction began June 17, 2019 on a $42.4 million project in Auburn. The project will rehabilitate existing pavement and drainage, improve operational features and upgrade pedestrian and bicycle facilities.

September 27 – October 2

State Route 49 (Placer County) from the Interstate 80 junction to Dry Creek Road: Motorists may expect intermittent lane and shoulder closures from 6 p.m. to 6 a.m. Sunday through Thursday for electrical and drainage work, roadway excavation, and curb and sidewalk work.


State Route 49 (Nevada County) at Wolf Road/Combie Road: Motorists may expect intermittent lane and shoulder closures from 8 p.m. to 5 a.m. Monday through Wednesday for a striping operation.


Construction crews are expecting to complete drainage work this coming week on Highway 49 northbound near the railroad overcrossing between Luther Road and New Aiport Road. The #3 lane (slow lane) is temporarily blocked by concrete barriers and construction barrels while this work is underway. Should work be completed, the concrete barriers and construction barrels are anticipated to be removed early the following week.

Construction crews have also finished demolition on all curb ramps that are being replaced at various locations along the highway to meet Americans with Disabilities Act (ADA) standards for sidewalks and intersection crossings. These areas are now being graded for future conrete work and new curb ramp installation. Sidewalk work also continues next week on northbound Highway 49 between Palm Avenue and Nevada Street/Marguerite Mine Road.

Electrical contractors also continue traffic signal installation and testing for new, upgraded signal poles that meet current Transportation Department standards.
