US 101 Corridor Mobility Plan: San Luis Obispo

Connecting communities within and across the region to improve travel time reliability, safety and modal choices for the efficient movement of people and goods.

Several needs areas have been identified in the US 101 Corridor throughout the City of San Luis Obispo to address issues brought forward by both the public and technical analyses performed as part of this study. SLOCOG and the consultant team are seeking your input on which improvement concepts will work best to improve mobility and access along this important transportation route, while preserving the unique environment that makes San Luis Obispo County a great place to live.

The segments of US 101 through San Luis Obispo showed up as a priority in the first phase of the US 101 Corridor Mobility Plan because the parallel routes experience peak period congestion, there is no frontage system through much of the city. Addtional issues noted by both the study team and the public were the number of on and off ramps with short acceleration and deceleration lanes, and the lack of bicycle and pedestrian routes across and along the corridor.

We are looking for comments on improvements proposed for Arroyo Grande and Pismo Beach, San Luis Obispo, Atascadero, or Paso Robles. Essentially, this study will prioritize improvements that enhance mobility on US 101 by reducing congestion. Improvements providing the most benefit to the highway will have the highest priority, while those showing limited or no benefits to the highway will not be considered in this study.

To provide input, click on a needs area to see the proposed improvement concepts. You may provide comments on the improvement concepts shown, or you can suggest another option that is not listed. All public input will be summarized to help inform the development of a multi-modal improvement package for each Focus Segment.
