I-280/I-880/Stevens Creek Boulevard Improvements Project
Improvements are completed at the 280/880/ Stevens Creek Boulevard interchanges. The project began construction in late Fall 2012. Its purpose is to improve traffic flow, safety and access between the Interstate 280 (I-280) and Interstate 880 (I-880) freeway corridors near Stevens Creek Boulevard, including modifications to the freeway-to-freeway intersection of State Route 17 (SR-17)/I-280/I-880 freeway interchange, as well as the adjacent interchanges at I-880/Stevens Creek Boulevard.
Specific improvements include:
- Reconfiguration of the full cloverleaf I-880/Stevens Creek Boulevard interchange to improve traffic flow in the surrounding interchange area by widening and realigning ramps.
- Widening the overcrossing structure at Stevens Creek Boulevard over I-880, improving intersections and providing enhanced access for pedestrians and bicyclists.
Separating freeway-to-freeway traffic from local traffic by construction of a new direct connector from northbound I-280 to northbound I-880.
Construction of direct off ramps to Monroe Street from Southbound I-880.
