Highway 49 Placer County Rehabilitation Project

Highway 49 Rehabilitation Project Construction Update

Sunday through Saturday, July 12 – July 18, 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.

July 12 – July 17

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. Monday through Thursday for electrical and curb and sidewalk work.



No traffic-interfering work is scheduled this week.



This past week construction crews re-striped a segment of State Route 49 between Palm Avenue and Nevada Street/Marguerite Mine Road, shifting northbound traffic to the left. As a reminder, the median turn lane between Persimmon Terrace and Nevada Street/Marguerite Mine Road will be utilized for northbound traffic, preventing southbound left turns for several months. Southbound motorists may access businesses via Palm Avenue and Auburn Ravine Road.

This upcoming week temporary concrete barriers, or k-rail, will be installed along the northbound side of SR-49 between Palm Avenue and Nevada Street/Marguerite Mine Road. You may see crews performing widening and grading work during daytime hours behind the safety of the k-rail. No daytime traffic-interfering work is anticipated during the construction of the sidewalk and bike lane in this area.

Electrical upgrades for the traffic signal system are continuing along most of the project route. Crews will also begin installing new traffic signal poles at various locations along the project route. 

This week crews will begin curb ramp demolition at Bell Road, Luther Road and Hulbert Way intersections. They will also begin pouring concrete for Americans with Disabilities (ADA) compliant curb ramps and sidewalks at Willow Creek Drive, Education Street, Atwood Road and New Airport Road.

In addition, roadway excavation along the northbound SR-49 embankment between Hulbert Way and the railroad overcrossing may occur next week. This work is in preparation for new ADA compliant sidewalks.
