Moving SLO Forward

Traffic relief is on the way for the busy Los Osos Valley Road/U.S. 101 interchange in the City of San Luis Obispo! In addition to improvements on the northbound and southbound ramps, we’re constructing a new two-lane bridge over the 101 to add more capacity to the existing 52-year old overcrossing. The new bridge will have bike lanes and sidewalks for pedestrians. The project also includes widening the existing bridge on Los Osos Valley Road over San Luis Obispo Creek.

Construction is scheduled to begin this fall and be completed in the summer of 2016. The City of San Luis Obispo is taking steps to minimize disruptions for residents and businesses near the project site.Lane closures will be kept to a minimum and we have created a schedule that keeps all lanes open during the holiday shopping seasons.

We are committed to keeping you informed about the project. This website will provide the latest information about lane closures and the progress of the project. We invite you to explore the site to learn more about the project and connect with us on Facebook and Twitter. You can also sign up for email alerts about lane closures using the form to the right.
