Caltrans (the California Department of Transportation) and the City of San Mateo have modified the interchange between State Route 82 (SR 82/El Camino Real) and State Route 92 (SR 92) to reduce traffic congestion, bottlenecks, weaving, and queuing spillback at the on and off ramps. 

Existing ramps were widened and reconfigured from a full cloverleaf to a partial cloverleaf. Pedestrian and bicycle improvements were also included. 

Caltrans determined that this project would not have a significant impact on the environment. The report that explains this is called the Initial Study with Proposed Negative Declaration, and is available below.
