Pontoon Roadways and Bridges
Providing complex program management, engineering and manufacturing excellence for pontoon roadway and bridge construction.
Specially engineered pontoon roadways and bridges support large cargo off-loads and bridge surf zones to provide a crossing point between lighterage, cargo vessels, and the beach. Jered’s complex project management experience and engineering and manufacturing expertise allow us to design and construct lightweight, flexible roadways that offer extensive load capacity.
Case Study: Elevated Causeway System/Modular
The U.S. Naval Facilities Command required a large Elevated Causeway System/Modular (ELCS(M)) to support large cargo off-loads in areas with no pier facilities or where facilities need support with additional resources. Jered was selected for this project because of our demonstrated capability with large, complex program management and expertise in the engineering and manufacturing disciplines required. The ELCS(M) designed by Jered is a new generation of elevated causeway system whose size and shape is standardized to fit ISO containers. This helps ensure simplicity of transport, mobilization and deployment during contingency operations.
Unique Modular Design Allows Flexibility in Deployment
The pontoon roadway supports two-way truck traffic, and the modular design of the pontoon roadway section accommodate varying beach gradients to satisfy the water depth requirement. This modular design allows the length of the roadway from the beach ramp to the pierhead to vary by up to 67 pontoon sections. These improvements to the previous generation of elevated causeway systems provide safer and simplified transport, installation, and assembly.
Features and Components of the ELCS(M) System
The ELCS(M) system is made up of connected steel pontoons elevated on piles that extend seaward across the surf zone up to 3000 feet from the beach. Actual installation length is determined by the requirement to reach a maximum water depth at the pierhead of 20 feet.
Comprising the system are the ELCS(M) facility, the marshaling yard system, and the barge ferry system. The ELCS(M) facility is an elevated modular pontoon structure (or pier) with a beach ramp and a variable-length roadway that extends to the seaward point of the pierhead. It includes the pier system, a lighting system, safety, navigation, and cargo handling systems.
