I-80 Atlantic Westbound On-ramp Widening Project
The California Department of Transportation (Caltrans), in cooperation with the City of Roseville Public Works Department (City), is widening the Atlantic Street/Eureka Road/Interstate 80 Westbound on‐ramp, which would expand the width of the existing Atlantic Street/Eureka Road/Interstate 80 on‐ramp to include three lanes. In addition, the project would replace the existing Miner’s Ravine Bridge (Bridge No. 19-0056K) over Miner’s Ravine to support the newly widened roadway. The widened on-ramp will reduce traffic congestion and comply with current design standards.
Purpose and Need:
The purpose of this project is to reduce traffic queues on the ramp which adversely impact local intersections by improving the ramp's storage capacity. The combination of high demand, a short storage length, and ramp metering on the single‐lane I‐80 Westbound Atlantic Street onramp results in significant queuing which negatively impacts the operations of local streets and intersections.
The project would provide additional lanes on the westbound on‐ramp so that the peak hour traffic demands may be adequately served without affecting local street operations along Atlantic Street and Eureka Road.
