The San Mateo-Hayward Bridge is a seven mile (11.km) long structure that crosses the San Francisco Bay between Foster City, a suburb on the eastern edge of San Francisco and Hayward in the East Bay. It is the longest bridge in California and the 25th longest fixed-link bridge in the world.
Whether you're driving in the morning or at night, the san mateo bridge is always a fun place to visit. You can cruise along the high-rise section in Foster City and see some really nice views of the city, the tan hills on the west, and the blue water on the east.
There are a total of six lanes on the bridge, with two lanes each way on the western highrise span. There are also three lanes each way on the lowrise trestle eastern causeway.
The san mateo bridge was the first to be constructed with an epoxy asphalt concrete (EAC) riding surface. This is a sole source material made from a mix of epoxy resin and asphalt concrete mixed at high temperatures.
The EAC material is designed to be stiffer at higher temperatures than conventional asphalt concrete. This results in a higher modulus of elasticity and greater structural integrity than conventional asphalt. This allows for a 12% - 15% lighter riding surface.
