Work continues on several other mov- able bridges in Florida. With the Intracoastal Waterway running along vir- tually the entire eastern coast of Florida, and many bridges due for replacement, Florida will continue to be the center of

The light weight and long span capaci- ty of the Exodermic design have been key factors in its selection for use on several major bascule bridges in Florida, where the DOT has mandated the use of closed deck systems wherever feasible.

Florida Bascule Bridges Feature Exodermic Decks

All four leaves of the 17th street Causeway Bascule Bridge in Ft. Lauderdale were fully opened to traffic in September, 2001. Finish painting of the bridge and the segmental concrete approaches was completed in the early spring and the bridge was dedicated on April 13th. It is one of Florida’s busiest bridges in terms of number of openings, and it is stunningly beautiful.

Another project with a strong empha- sis on aesthetics is the Hallandale Beach Bridge, just 8 miles (13 km) south of the 17th Street Bridge on the Intracoastal Waterway. The first of the twin bascule bridges at Hallandale Beach opened to traffic in April, 2001. After considerable study, difficulty in aligning the first bridge was attributed to inadequate stiffness in the leaf. This is being addressed on the second bridge with heavier permanent lateral bracing, some temporary top later- al bracing, and more adjustability of the rack assembly. The project is scheduled for completion in February, 2003.

Dutch contractor Ballast Nedam has begun work on yet another beautiful Florida bascule bridge. The Royal Park Bridge will carry Route 704 (Royal Palm Way), the main route across the Intracoastal Waterway, into West Palm Beach. While the main bearing bars of the Exodermic decks on 17th Street and Hallandale Beach bridges span longitudi- nally over 14 feet (4.4 meters) floor beam to floor beam without stringers, the Royal Park Bridge is more conventional in con- struction, with main girders, floor beams, and stringers, though the stringers are fairly widely spaced at 9.5 feet (2.9 meters). Due to the use of 115 lbs./cf (1846 kg/cu. meter) sand lightweight con-

One of the busiest bascule bridges in the U.S., the bascule span of the 17th Street Causeway Bridge is the signature bridge for Ft. Lauderdale and its port, home to many world class yachts. Its Exodermic deck spans 14.4 feet floor beam to floor beam, without stringers.

Construction is just beginning on the Royal Park Bridge in West Palm Beach, but the result will be another beautiful bascule bridge for Florida. Its Exodermic deck will provide a reinforced concrete riding surface, but at much lower weight than a standard concrete slab.
