What is the purpose of this project?

This project will replace an aging and obsolete 500-foot long bridge with a new 3700-foot long bridge. As part of this project, the existing causeway and bridge will be removed, and wetland restoration and enhancement efforts will begin. The proposed structure will have a closed drainage system which will collect the water from the bridge and carry it to stormwater ponds for water quality treatment.

Why is it necessary?

The Lake Jesup Design-Build project will both improve the environment and construct a new bridge to current standards with wider lanes and shoulders. Removal of the causeway will increase hydraulic connection between the river and lake, and the newly designed bridge will include a closed drainage system to collect water from the bridge and carry it to stormwater ponds for water quality treatment. The existing causeway will be graded down to an elevation conducive to the creation of new wetlands, and additional restoration and enhancement will take place to help restore the historic marsh system in this area.

What is a Design-Build project?

Under a Design-Build contract, a general contractor is hired to complete the design of the project and then construct it. Under a Design-Build contract, a single source is responsible to the owner for both design and construction. The Design-Build team will be responsible for quality, innovation, protection of existing resources, safety, cost and schedule.

How much will the project cost?

Anticipated total cost to replace the bridges and to complete the associated improvements is $40 million (in 2008 dollars). This cost includes design engineering, construction, floodplain/wetland mitigation, and removal of the existing bridge and causeway.

When will the project be completed?

The Design-Build contract was awarded in early 2008 and construction is scheduled to be completed sometime in Spring 2010.

What impacts will there be to the environment?

The Florida Department of Transportation (FDOT) has worked closely with federal, state and local regulatory agencies to minimize impacts to the environment, and to effectively mitigate for any impacts that might occur. Mitigation for unavoidable wetland impacts will be consistent with federal regulations and state statutes. Proven methods will be followed during the demolition of the existing bridge and construction of the replacement bridge in accordance with federal, state and local criteria and regulations, to minimize environmental impacts.

What are you doing to preserve the history of the bridge?

The project team recognizes the value of historic preservation. Working in partnership with the Friends of Lake Jesup, permanent signage will be erected near the new bridge and boat dock to commemorate the old SR 46 Lake Jesup Bridge. Historical photos and stories from the local community will be featured.
