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. The final version of the new interchange layout is available for review.
