State Route 47 North


SR 47 (Alameda Street) north passes under the Alameda Corridor that carries rail traffic from the Ports of Los Angeles and Long Beach north to the Union Pacific Railroad mainline near downtown Los Angeles.

Leaving San Pedro "A Whale of a Town", SR 47 heads east to the Vincent Thomas Bridge between San Pedro and the Port of Los Angeles on Terminal Island. Older guide signs for the bridge once referenced the toll rate. Tolls for the crossing were eliminated in 2000.

07/09/18
According to the San Pedro community webpage, "San Pedro's Golden Gate" was the first suspension bridge to be built on pilings. Tolls were collected from the time of opening in 1963 until 2000, when it was one of two remaining Southern California toll bridges (the other was the San Diego-Coronado Bridge, which ceased toll collection in June 2002).
07/09/18
Statistically speaking, the Vincent Thomas bridge "required 92,000 tons of Portland cement; 13,000 tons of lightweight concrete; 14,100 tons of steel; and 1,270 tons of suspension cable." (The bridge) is designed to withstand winds of 90 miles per hour, double that required by code. The overall length of the bridge is 6,050 feet, with a main suspension span of 1,500 feet and 500-foot spans on either side. The towers are 365 feet high."1
07/09/18
The suspension bridge is named for former State Assemblyman Vincent Thomas, a legislator who championed the bridge's construction and was present to open the crossing to traffic in 1963. The bridge was constructed at a time when the Port of Los Angeles and Port of Long Beach were still growing and gaining traffic volume, so its importance grew as it served more trucks and commercial traffic associated with the port.
