It was the second bridge built across the river. It carries four lanes of traffic, and is signed as US 1/US 90 (SR 5/SR 10). A lift bridge, it opened in July 1941^[1] at a cost of $1.5 million.^[2] In 1957 it was named after Mayor John T. Alsop Jr., but continues to be known, even on road signs, as the Main Street Bridge.
