U.S. 101 Improvement Project (Capitol Expressway to Yerba Buena Interchange)

Detour Information:

Temporary ramp and lane closures for May, 2013 may be required, weather and conditions permitting. 

Construction activities overnight, beginning Tuesday evening, May 14-Friday night/early Saturday morning, May 18, will have potential noise and vibration impacts, depending on your location.  

**Beginning April 11, 2013 a detour of Eastbound Capitol Expressway to Southbound US 101 thru Yerba Buena Intersection will be in place. This detour will continue for approximately 6 months for the construction of a new off-ramp to Yerba Buena and auxiliary lane.

Project Overview

The project will make improvements to Interchange at Capitol Expressway and ramp modifications at Yerba Buena Road.

Objective

The purpose of this project is to reduce traffic congestion and improve safety along the U.S. 101 corridor in east San Jose by eliminating mainline traffic bottlenecks and removing merging and weaving conflicts. 

Project Features

The proposed improvements would: 

• Construct a separate Yerba Buena Road off-ramp from southbound U.S. 101
• Construct a southbound U.S. 101 auxiliary lane between the Capitol Expressway and Yerba Buena Road.
• Modify Capitol Expressway Interchange from full cloverleaf to partial cloverleaf.
• Extend the fifth southbound lane from north of Capitol Expressway to south of Yerba Buena Road.
• Construct northbound slip on-ramp from northbound collector - distributor road.
