ROSEVILLE – Caltrans is alerting motorists about an upcoming 55-hour closure of the Riverside Avenue off-ramp along westbound Interstate 80 (I-80) as part of the $46.1 million Auxiliary Lane and Fifth Lane Project.
The off-ramp is scheduled to be closed from 9 p.m. Friday, July 12 to 5 a.m. Monday, July 15. Motorists looking to exit Riverside Avenue will detour westbound along I-80 to the Antelope Road exit. At the stoplight, make a left and then take the I-80 eastbound on-ramp, where they will be able to head back to the Riverside Avenue/Auburn Boulevard exit. During this time crews will excavate the roadway, install new lighting and repave the ramp to accommodate the new fifth lane.
A similar closure is scheduled for the loop on-ramp from 9 a.m. Friday, July 26 to 5 a.m. Monday, July 29. Motorists will detour east on Orlando Avenue, turn left onto Cirby Way and make another left onto Riverside Avenue to access the slip on-ramp to westbound I-80.
Ghilotti Construction Company, Inc. of Santa Rosa is the prime contractor. The entire project completion is expected by the end of fall 2024. At that time, the interstate will have an auxiliary lane on eastbound I-80 between State Route 65 and Rocklin Road and include a two-lane off-ramp. A fifth lane will be constructed on westbound I-80 between Douglas Boulevard and Riverside Avenue and include reconfiguring the Douglas off-ramp from two lanes to one lane.
