What kind of bridge is this in the United States?

This is the Benjamin Franklin Bridge in the United States.

The Benjamin Franklin Bridge, also known as the Ben Franklin Bridge, was originally named the Delaware River Bridge. Bridge is a suspension bridge across the Delaware River, connecting Philadelphia and Camden, New Jersey. In order to commemorate the famous American statesman Benjamin Franklin, the bridge was renamed to its current name.

The plan to build this bridge had already been conceived in 1818, and the completion of this bridge successfully replaced the early reliance on ferries to cross the Delaware River.

In 1919, representatives from Philadelphia and New Jersey began planning to build a new bridge. They hired architects Ralph Modjeski and Paul Philippe Cret to jointly design a suspension bridge spanning 533 meters. Once completed, the bridge was the largest suspension bridge in the world at the time. After the completion of the Washington Bridge in New York in 1931, the Benjamin Franklin Bridge lost this title.

Construction of the Ben Franklin Bridge began in 1922, but a dispute ensued between New Jersey and Philadelphia. New Jersey wanted to build a toll booth on the bridge, while Philadelphia wanted the bridge to be free, with taxes to pay for its construction. It was this dispute that stalled the project for a time, until Philadelphia finally agreed to build the toll station before construction could continue.

This blue bridge was officially opened to traffic on July 1, 1926. At that time, it was named Delaware River Port Authority Bridge (Delaware? River? Port? Authority Bridge), referred to as Delaware river bridge. In 1956, the bridge was renamed the Benjamin Franklin Bridge in honor of Benjamin Franklin, one of the founders of the United States and one of Philadelphia's most famous figures.

The bridge now has six lanes, two tram tracks, and a railway line located outside the bridge's upper-supporting trusses. Because the tramway was never used, it was later converted into a car lane. The railway line came into use in 1936.

In 1987, a computer-controlled lighting system was installed on the bridge as part of the Bicentennial celebration of the US Constitution, making the bridge one of Delaware's most iconic landmarks at night. The brightest star on the river.

In addition, there is no sidewalk on this bridge, but the sidewalk will be open regularly, from 6:00 in the morning to 18:00 in the evening (19:00 in summer time). However, the day after the London bombings on July 7, 2005, the U.S. Department of Defense temporarily closed the sidewalk to the public due to security concerns. Additionally, sidewalks are closed during snowfall.
