T.Y. Lin International (TYLI) was retained by the U.S. Army Corp of Engineers (USACE) to serve as a third-party reviewer of construction submittals and to provide engineering consultation for the erection and transport of the P954 Flyover Bridge in Bahrain. Construction of the network tied-arch bridge was commissioned by the U.S. Navy in Bahrain.

Along with reviewing submittals, TYLI was charged with overseeing the status of bridge erection, performing onsite observations of the structure, identifying any potential engineering issues that could impact bridge transport, and providing engineering support services during an overnight operation to transport and install the bridge over the Prince Khalifa Bin Salman Highway.

Project Highlights:

  • The 122-meter-long P954 Flyover Bridge carries a 2-lane roadway and a pedestrian walkway, with a 16-meter-wide bridge deck of post-tensioned concrete.
  • The entire bridge was built on falsework at an offsite facility about 250 meters away from the permanent location across a major highway.
  • The rapid construction method reduced impacts on the traveling public while allowing complete bridge accessibility from all directions for the delivery and movement of equipment during construction.
  • Self-Propelled Modular Trailers (SPMT) or Transporters were employed to move the 2,404-tonne flyover bridge into place, accelerating construction operations and minimizing traffic interruptions.
