Connecting the San Francisco Peninsula to the East Bay is the San Mateo-Hayward Bridge, which is often referred to simply as the San Mateo Bridge. The original structure had to be replaced during the 1960s because the area had become overcrowded and the aging bridge was severely overcrowded. The new bridge cost a whopping $70 million and had two lanes in each direction.
