SR 99/120 CONNECTOR MILESTONE - FINAL GIRDER INSTALLATION
This video celebrates a major milestone in the State Route 99/120 Connector Project as our team of contractors completes the final girder installation for the new Austin Road overcrossing. It showcases the impressive progress happening across the corridor and the momentum that is building as crews move to the next phase of construction. With more than 180,000 vehicles traveling through this interchange each day, this project is delivering long-awaited improvements that will make travel safer, smoother, and more reliable for commuters and businesses throughout the region. The project remains on track for completion in summer 2026, and the San Joaquin Council of Governments invites the community to stay connected by signing up for ongoing construction updates.

Supports are all that remain of the 1950s-era Austin Road Overcrossing, or bridge, in Manteca. The overcrossing is being removed as part of the State Route 99/120 Connector project and will be replaced later with a wider structure to span a wider State Route 99 and Union Pacific Railroad tracks.
