EFIS Project ID: 0419000050

San Mateo County Transportation Authority (SMCTA) and City / County Association of Governments (C-CAG) of San Mateo County, in 2018 conducted a Preliminary Planning Study (PPS) to address the congestion and safety concerns in the vicinity of the US101 / SR 92 interchange. Short-Term and Long-Term alternatives were identified during the PPS. This project carries forward the Short-Term area improvements, which focus on addressing existing deficiencies, and are non-complex improvements with relatively low implementation costs, and no right of way acquisition is anticipated since the improvements can be constructed within the existing right of way.
