The I-580 freeway is a vital transportation link connecting the San Francisco Bay Area with the Tri-Valley and the Central Valley areas. As a result of the rapid growth in these areas, the 10-mile I-580 Corridor in eastern Alameda County ranks among the most congested corridors in the Bay Area. This 10-mile corridor accommodates Bay Area Rapid Transit’s (BART’s) extension in the median of the freeway. It also uses advanced technologies and real-time system management techniques to manage and balance traffic flows and speed on the freeway corridor and the adjacent arterial streets parallel to the north and south of the freeway.
- Widening the freeway to five lanes
- Providing for BART trains in the corridor median
- Creating a transportation management plan for the deployment of ITS
- Creating HOV and auxiliary lanes
- Adding a HOT lane
T.Y. Lin International’s planning and detailed design services for a full multi-modal solution for this corridor have included widening eastbound I-580 to five lanes; providing for BART trains in the corridor median; creating high occupancy vehicle (HOV) and auxiliary lanes; and adding a high occupancy toll lane. Additionally, T.Y. Lin International created an integrated transportation management plan for the deployment of Intelligent Transportation Systems (ITS) at targeted locations along I-580. The resulting improvements significantly facilitate mobility for both people and goods by reducing congestion and delays and providing transit links.
