The Sam Rayburn Tollway (SRT) is an all-electronic tollway that stretches 26 miles southwest to northeast, linking the Dallas Fort Worth International Airport to the growing communities in Collin, Dallas and Denton counties. As part of a larger program to upgrade the SRT/Dallas North Tollway (DNT) interchange, STV performed design services for Segment 5 of improvements.
The team’s scope included layout development and plans, specifications and estimates (PS&E) design of four direct connectors; the structural design of retaining walls and drainage structures; and illumination and traffic control plans. The structural design leveraged prestressed and reinforced concrete and structural steel elements. The firm designed superstructure and substructure elements including prestressed concrete beams, steel plate girders, concrete abutments, single column bents, straddle bents and drilled shaft foundations and footings.
STV developed a proposed aesthetic theme for the project and presented information on existing and proposed themes to the general engineering consultant for consideration by the North Texas Tollway Authority. Additionally, the team coordinated extensively with other disciplines to see that existing traffic was maintained through the interchange during construction.
