Carrying U.S. Route 1 (Federal Highway; unsigned State Road 5), it was built to supersede the old Roosevelt Bridge, which had twin parallel drawbridges, one for northbound traffic (opened in 1934, 27 ° 12 ′ 12" N 80 ° 15 ′ 35" W ﻿ / ﻿ 27.203228 ° N 80.259612 ° W ﻿ / 27.203228; - 80.259612) and the other for southbound (opened in 1964, 27 ° 12 ′ 09" N 80 ° 15 ′ 35" W ﻿ / ﻿ 27.202475 ° N 80.259762 ° W ﻿ / 27.202475; - 80.259762). The new bridge, completed in 1996, is raised and much longer than the older twin drawbridges . The southbound span of the old bridge is still functional for road and boat traffic and now carries two - way road traffic for what is now known as Dixie Highway, County Road 707 . The new high - level Roosevelt Bridge is approximately one mile long and is made of two three - lane sections running parallel to each other . The northbound bridge was completed first, and housed two lanes of both north and south - bound traffic until the second bridge was finished . </P>
