Project Details

S&B provided engineering and management services for layout and an environmental assessment for the relocation of the railroad mainline and bridge spanning the Rio Grande River to connect South Texas with relocated rail facilities in Mexico. We coordinated project development and identified potential funding for the construction phase with the US State Department, TxDOT and the Federal Highway Administration.

We prepared preliminary bridge layouts based on UPRR and AREMA Manual of Railway Engineering Design and Detailing Criteria. Layouts included hydraulic data and results of potential scour analysis, as well as structure type, spans, foundation type and freeboard above calculated high water elevations.

We also developed alternatives for bridge width, structure type, proposed material and steel versus concrete superstructure spans. S&B assisted with the final design of bridge substructure details for the river crossing, as well as superstructure details for the spans over US 281, and the approach spans south of the main river spans.
