4) Ralston/101 Interchange Project
Project description: Route 101, in and around the Ralston Avenue Interchange has been one of the most congested areas on the peninsula for years – a by-product of the economic vitality of the Redwood Shores and Route 101 businesses. This project will give motorists a better facility free from congestion by making major improvements to help the flow of traffic.
The project will improve the efficiency of this interchange during peak traffic hours by reducing the need for motorists to weave in and out of traffic lanes to get to their destinations. The two off-ramp loops will be eliminated, and traffic will instead come to two new signalized intersections. Island Parkway will be realigned and connected directly to Marine Parkway at one of the new off-ramp intersections.
