The project included construction of an elevated guideway composed of prestressed concrete double tee beams and steel box girders with a cast-in-place concrete deck, side walls, piling, foundations, columns, and walls. Steel box girders were erected between the existing Acosta Bridges, supported by detailed planning and a carefully executed heavy-lift strategy. Superior also built the elevated, three-story San Marco Station on concrete pile foundations, incorporating architectural finishes and passenger amenities.
In addition, teams constructed a two-story Operations and Maintenance Center using split-face masonry block, with a footprint of approximately 12,700 square feet. Work included spread foundations, slabs on grade, concrete hollow core slabs, structural steel framing, and a steel roof structure, along with installation of specialized maintenance equipment and computer access flooring. Superior crews completed site utilities, restored disturbed areas, installed landscaping, and added wayfinding graphics.
Upon completion, the project extended Jacksonville’s transit network across the St. Johns River, connecting key destinations and expanding mobility options for residents, workers and visitors. The new operations and maintenance facility supports JTA’s autonomous transit fleet and reflects Superior Construction’s ability to deliver complex infrastructure projects involving heavy-lift operations, structural systems, building construction, and site development.
