The purpose of this project was to relieve existing and future traffic congestion along U.S. 101 between State Route 85 in Mountain View and Embarcadero Road in Palo Alto, and to improve safety along the U.S. 101 corridor in Santa Clara County by eliminating bottlenecks while providing additional capacity for vehicles to merge.
The project improvements included:
- Constructed auxiliary lanes between on-ramps and off-ramps
- Extended existing high-occupancy-vehicle (HOV) Lanes
- Widened and modified on-ramps and off-ramps at each interchange to improve efficiency of the auxiliary lanes
- Improved traffic operations on the freeway by providing more room for traffic entering and exiting the freeway at each interchange
- Allowed traffic traveling from one interchange to the next interchange to use the freeway without impacting the main through lanes
Caltrans operates and maintains the highway improvements.
