Document Description
The proposed project includes widening of Highway 1, from the Freedom Boulevard interchange to the State Park Drive interchange, to provide auxiliary lanes that would connect the interchange entrance and exit ramps, thereby extending the weaving and merging distance between the ramps. The project also includes bus-on-shoulder features that would support future bus operations on the shoulders of Highway 1 during peak congestion periods. Additionally, the project includes construction of a bicycle and pedestrian trail along the Santa Cruz Branch Line railroad right of way, from State Park Drive to Rio Del Mar Boulevard.
