State Route 41 Ashlan to Shaw Auxiliary Lane

Project Description

Caltrans proposes to construct an auxiliary lane on northbound State Route 41 from the northbound Ashlan Avenue on-ramp to the northbound Shaw Avenue off-ramp. The project would also widen the Shaw Avenue northbound off-ramp to two lanes to accommodate the addition of the new auxiliary lane.

Project Benefits


The project would relieve congestion and improve safety for this segment of northbound State Route 41. The addition of the auxiliary lane within the project limits would improve traffic operations on mainline State Route 41 and the northbound State Route 41 off-ramp to Shaw Avenue.


The project is needed because of increasing congestion and rear-end collisions that occur on this segment of the roadway. Accident data for that segment from 2013 to 2015 revealed that fatal-plus-injury and total accident rates were higher than the statewide average for similar roadways with comparable traffic volumes. There were 91 accidents within that period. The total fatal-plus-injury accident rate per million vehicle miles traveled for the project area was 0.84, while the statewide average was 0.30.
