Project scoping completed in 2021 identified two build alternatives, construction of a viaduct (Structure above Mission Boulevard) and a trench (below Mission Boulevard) along with interchange modifications at the I680/SR 262 Interchange and bicycle and pedestrian facilities within the project limits to separate the regional and local traffic, address existing operational deficiencies and recurring traffic congestion along Mission Boulevard/SR 262 and adjacent I-680 and I-880 freeways and encourage the use of alternative transportation mode within the project limits. However, in early 2024, the project scope was significantly reduced to advance two of the previously approved project goals: to improve traffic operations at the I-680/SR 262 Interchange and construct a safe, high-quality bicycle and pedestrian facility within the project limits to encourage the use of an alternative transportation mode that meets all ages and abilities criteria, where feasible.
The reduced scope project will include the following improvements:
- Modify the I680/SR 262 Interchange
- Construct a separated bicycle and pedestrian facility, where feasible, from Warm Springs Boulevard to east of I-680/SR 262 Interchange
