The Florida Department of Transportation (FDOT) enlisted Orion to embark on a critical infrastructure project: the construction of two high-level fixed bridges spanning the Indian River. The existing bascule bridge, dating back to 1964, presented numerous deficiencies, compelling FDOT to seek its replacement for the safe and efficient transportation of freight and launch materials. Recognized as a crucial thoroughfare for essential mission hardware, the new bridges would serve as the primary corridor for commercial spaceflights undertaken by industry giants such as SpaceX and Blue Origin.

Our Marine group, in turn, engaged the expertise of our Engineering & Consulting group to address the intricate challenge of designing alternate Maintenance of Traffic (MOT) phases. This strategic planning aimed to facilitate our Marine team in setting spans 1 through 5 with a single 2250 crane from land. The primary objectives were to reduce construction duration and establish a safer work zone. We not only developed two additional MOT phases but also revised a key phase linked to the construction of the eastbound bridge structure.

The comprehensive design envisioned by our Engineering & Consulting team incorporated innovative elements, including the introduction of additional temporary pavement and a lane shift for both eastbound and westbound traffic. This strategic approach ensured that all four existing lanes could remain open throughout the construction of the new eastbound bridge span. Our dedicated staff went on to provide the design and meticulously crafted plans, which were then subjected to rigorous review and approval processes involving the original engineer of record, NASA, and FDOT. This collaborative effort aimed at meeting the highest standards and ensuring the successful realization of this ambitious bridge construction project.
