Location: Jupiter, Fla.
Cost: $11.6 million
Length: 0.6 miles
Designer: BHA Engineers
Contractors: Johnson Bros. (contractor); RS&H (CEI)
Owner: Florida DOT, District 4
Using top-down construction methods, the U.S. 1 team replaced four low-level bridges along U.S. 1 over the Lake Worth Oxbow, which is designated an Outstanding Florida Water. The designation meant the team had to employ innovative construction methods to protect the environment of the waterway. The construction involved temporary work trestles at each of the four bridge locations. The trestles were built so the cranes used to demolish the old and erect the new structures were able to move over the top of the structure with no impact to the waterway below.
