Huval and Associates prepared final bridge plans and live load rating reports for the project in accordance with the AASHTO LRFD Bridge Design Specifications, Bridge Design & Evaluation Manual, American Railway Engineering and Maintenance of Way Association (AREMA) Manual, and the BNSF Guidelines for Railroad Grade Separation Projects.

The project required a new US 90 overpass structure at Albertson Parkway and also required that the existing US 90 BNSF Railway overpass structure to be replaced. Huval is also responsible for the design of the frontage road bridges over the BNSF Railway.

The US 90 BNSF Railway overpass was designed with a 34.1-degree skew and required three construction phases in order to maintain vehicular traffic. The approaches are 120 feet BT-72 p.c.c. girders spans and the main span is a 136 ft. BT-72 p.c.c. girder span.

The US 90 overpass over Albertson Parkway overpass consists of a BT-72 p.p.c. girder bridge with 120 ft. approach spans and a 136 ft. main span. The superstructure is supported by concrete column bents and pile footings. The overall bridge width is 125’6″.

Additionally, HUVAL provided construction engineering services for the contractor.
