TAM proposes several improvements for the interchange, ranging from moving bus stops and adding new traffic signals, to realigning on- and off-ramps and installing roundabouts to improve the flow of traffic and increase safety for all users. 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 improvement concept focuses on adding safety features for all users. North San Pedro Road will be widened to add two through-lanes in each direction and a multi-use path. On- and off-ramps will be realigned, new traffic signals will be installed, and a class III bike lane will be added just before the Merrydale Avenue intersection.

The long-term concept expands on the near-term improvements and involves realigning the northbound offramp to connect to an intersection with signals. Roundabouts will also be installed at the North San Pedro Road/Merrydale Road and North San Pedro Road/Civic Center Drive intersections.
