Five Cities Multimodal Transportation Network Enhancement Project

Project Description 

Caltrans, in partnership with San Luis Obispo County of Governments, is proposing a pilot project to address peak-period congestion on southbound US 101 by constructing a left-shoulder part-time travel lane from San Luis Obispo Creek to the railroad overhead in Pismo Beach. The southbound left shoulder would be widened to accommodate the lane, which would be open daily during periods of heavy afternoon traffic as well as special events. A new park-and-ride lot in Pismo Beach is also proposed.

Project Benefits

Purpose: The purpose of the project is to reduce travel delays that diminish the efficient operation of US 101 through Shell Beach and Pismo Beach in the south­bound direction during periods of heavy traffic volumes.

Need: US 101 within the project limits cannot efficiently manage existing traffic volumes that accumulate when large numbers of drivers exit the City of San Luis Obispo within a short period of time. This typically happens during the evening work commute, on summer weekends, and when there are popular events in the communities to the south.
