US 101 / De La Cruz / Trimble Interchange Improvements

The US 101 / De La Cruz / Trimble Interchange Improvements Project is intended to improve traffic operations for through movements on the local roadway and turning movements to and from the freeway ramps, as well as improve weaving and merging conditions along southbound US 101 between the loop on-ramp, loop off-ramp and the next downstream exit to Route 87. Upgrades are also needed to enhance the interchange to better accommodate bicyclists and pedestrians at this critical link across US 101, consistent with current Complete Streets standards. Lastly, the project will replace the existing outdated overcrossing structure that is too narrow, has insufficient clearance over US 101, and does not meet current seismic standards. The bridge replacement will need to be implemented without further encroachment into approach and departure glide slope surfaces for the runways at San Jose International Airport.

HMH will reconfigure the existing ¾ cloverleaf interchange into a partial cloverleaf and adds a grade separated Class I trail under the high-volume southbound ramps. The project includes two protected intersections to connect the Class I facility to existing city streets. The local roadway is identified as a Cross County Bicycle Corridor (CCBC) network in the Draft Countywide Bicycle Plan (Feb 2018) with a moderate to high priority for implementation. Also identified as an Across Barrier Connection (ABC), De La Cruz Boulevard/Trimble Road is one of a few connections across the US 101 freeway within the North San Jose area.
