Willow Road/U.S. 101 Interchange

Willow Road - US 101 Interchange
The City of Menlo Park is a project sponsor of the Caltrans project to update the interchange of U.S. 101 at Willow Road. The current "full cloverleaf" style interchange will be replaced with a "partial cloverleaf" which will eliminate the short merge weaves both on Willow Road and on the freeway and will create a more efficient way for all modes of traffic, including bikes and pedestrians, to get across the freeway at Willow Road. The project will replace the existing interchange with a new, wider bridge; add sidewalks on both sides, bike lanes on both sides and protected bike paths on both sides; and add two signalized intersections.

Current status


The project is currently out to bid, with a contract award expected by the end of 2016. Construction is expected to begin in early 2017 and continue for approximately two years. As the project progresses, construction staging and traffic impacts will be posted here.
