The City of Menlo Park is a project sponsor of the Caltrans project to update the interchange of U.S. 101 at Willow Road. This project was awarded to a contractor in February 2017, construction began in May 2017 and is expected to be fully completed in July 2019. The previous "full cloverleaf" style interchange has been replaced with a "partial cloverleaf" which eliminated the short merge weaves both on Willow Road and on the freeway. This creates a more efficient way for all modes of traffic, including bikes and pedestrians, to get across the freeway at Willow Road. The project replaced the existing interchange with a new, wider bridge; added sidewalks on both sides, bike lanes and protected bike paths along both sides; and added two signalized intersections.
