TAM proposes several improvements for the interchange to make it easier and safer to access Highway 101 and improve the flow of traffic. Proposed projects include restriping and widening the freeway. To gain an important understanding of the interchange area, the study examined the following:

• Existing Infrastructure
• Transit Routes and Intermodal Connectivity
• Weekday AM & PM Peak Period Congestion
• Crash Type and Severity
• Environmental Constraints

Many of the study’s recommended changes will make the interchange easier to use for drivers, bicyclists, pedestrians, and people using public transit. The proposals will also increase safety at the interchanges and on surrounding streets and pathways, allowing for smoother travel to, from, and across Highway 101 and local roads.

The near-term concept focuses on improving safety and traffic conditions on local streets and carries out a Caltrans project which proposes adding a roundabout at Civic Center Drive. The sidewalk on the north side of the Manuel T. Freitas Parkway overcrossing will be upgraded to a multi-use pathway. High-visibility crosswalks will also be added at Northgate Drive and Del Presidio Boulevard along Manuel T. Freitas.

The long-term concept expands on the near-term improvements and adds proposals to construct two two-lane roundabouts at the intersections of Northgate Drive and Del Presidio Boulevard along Manuel T. Freitas Parkway. Multi-use paths will also be provided in both directions between the two new roundabouts.
