Benefits of the Project

This project will create a safe and separated multiuse path across US-101 for both bicyclists and pedestrians. Currently pedestrians have a long and difficult route using steep spiral ramps that are not ADA-compliant connected by narrow sidewalks. Bicyclists are forced to use paint-only bike lanes and cross busy on- and off-ramps.

By providing a multiuse path, all users will be able to safely travel from one side of the highway to the other.
