is an (the Junipero Serra Freeway),
U.S. Route 101 (the Bayshore Freeway) in or near
San Mateo , and
Interstate 880 (the
Nimitz Freeway ). It also connects indirectly to Interstates
238 and
580 by way of Hayward's Foothill Boulevard, which carries Route 238 and flows directly into Route 92.
Between Half Moon Bay and Interstate 280, Route 92 winds through the Coast Range as a narrow, mainly undivided two and three lane highway with a switchback turn. The east-bound uphill portion was upgraded with a long passing lane. Between Interstate 280 and Interstate 880 it is entirely a divided multilane highway, including the toll
Hayward-San Mateo Bridge , the longest span across the
San Francisco Bay . East of Interstate 880 the route becomes a divided surface street in Hayward.
All of Route 92 that is not already a freeway or a toll bridge has been proposed as a freeway, none of which has been built. An upgrade of the intersection with Main Street in Half Moon Bay is in the late planning stage, and a grade separation at the route's Hayward terminus is planned.
