PTRA Hunting Bayou Bridge
LJA Rail performed the design for a double track, 210-foot pre-stressed concrete bridge with a 20 mile per hour design speed, crossing Hunting Bayou at the North End of American Yard. Besides the actual bridge design, LJA’s services included all track design, permitting to build the bridge including tidal permit, drainage structures, survey, soil samples, right-of-way exhibits, and the acquisition of required permits.
LJA Rail prepared the bid documents and specifications for the bid process, along with the actual bid packages to be sent out to prospective bidders. Once construction began, LJA provided on-site construction management services for the project including project oversight, daily and weekly reports, as-built drawings verification, punch list development, and construction support to address design questions during construction. The bridge project was constructed next to an existing railroad bridge with no interruptions to railroad traffic at any time during construction. LJA worked with the contractor to help ensure a safe environment that would not impact railroad operations.
