Document Description
Caltrans, in cooperation with the City of San Mateo and the San Mateo County Transportation Authority (SMCTA), proposes to relocate the U.S. Highway 101 southbound on- and off-ramps from East Poplar Avenue to Peninsula Avenue creating a full interchange at Peninsula Avenue and Airport Boulevard and improve bicycle and pedestrian access on the existing Peninsula Avenue overcrossing. The project would improve the safety of the freeway on- and off-ramps and improve circulation within the project area. Two Build Alternatives are under consideration, including on- and off-ramps in a spread diamond configuration and on- and off-ramps in a tight diamond configuration along with a No-Build Alternative. Both Build Alternatives would require property acquisitions adjacent to U.S. Highway 101.
