Interstate 5/Genesee Avenue Interchange

opening ceremony

Construction start: February 2015

Completed: June 2018

The $117.4-million Interstate 5/Genesee Avenue Interchange Project was funded through a partnership between the Federal Highway Administration (FTA), Caltrans, the San Diego Association of Governments (SANDAG), the City of San Diego and UC San Diego. Widening the Genesee Avenue bridge complements Genesee Avenue enhancements and improves local traffic circulation and freeway access.

The six-lane Genesee Avenue overpass was replaced with a ten-lane structure that better accommodates current and future traffic demands. Along with the overpass replacement, the project widened freeway access ramps and added an auxiliary lane in the northbound direction on I-5 between Genesee Avenue and Roselle Street.

The project included a Class 1 bicycle and pedestrian path — a dedicated path for the exclusive use of bicyclists and pedestrians — that links to transportation, employment centers, hospitals and the campus. At UC San Diego, this dedicated path runs east of the Campus Services Complex and can be accessed at the Gilman Drive/Voigt Drive intersection. It extends to the Sorrento Valley COASTER Station north of campus.

This project was a partnership between FTA, Caltrans, SANDAG, the City of San Diego and UC San Diego. Although the I-5/Genesee Avenue Interchange is not a UC San Diego project, the university was involved in planning to ensure minimal disruption to the campus during construction as well as the best possible outcomes for our students, faculty, staff, patients and visitors.
