Document Description
The City of San Luis Obispo proposes to extend Prado Road over U.S. 101 to connect with Dalidio Drive and rebuild the existing U.S. 101 northbound on- and offramp connections to Prado Road to provide congestion relief, operational efficiency, and multimodal connectivity. The interchange is in the City of San Luis Obispo at post mile 26.8 on U.S. 101. The purpose of the project is to improve overall circulation and accessibility in the project area for all transportation modes. There is a need to provide better community connectivity between the existing and planned neighborhoods east and west of the U.S. 101 freeway and resolve forecasted operational deficiencies on State and city facilities. This connectivity need extends to all transportation modes.
