Border Highway West Loop 375 Toll Road Bridges

El Paso

In order to improve congestion near the US/Mexico border, a new 11-mile, six-lane toll road was built adjacent to the border to provide an alternative east-west route to IH 10. This complex, fast-track project involved several Walter P Moore disciplines including bridge engineering, traffic engineering, transportation engineering, and ITS.

Walter P Moore designed the ITS, tolling system, traffic signals, signing, striping, and relocation of some border patrol facilities. Walter P Moore's traffic group met multiple challenges such as extensive placement of ITS and tolling devices on bridge structures to avoid Union Pacific and BNSF railroad track relocation and coordination between three levels of government and multiple utilities. As the traffic design task leader, Walter P Moore was responsible for oversight and coordination of all traffic and illumination activities and multi-disciplined coordination.

Walter P Moore's transportation group designed two bridges on the project, including the largest and most complex, a 61-span structure with seven post-tensioned concrete bridge caps supported on 10' diameter drilled shafts. The Walter P Moore transportation group also served as the bridge design task leader, responsible for oversight and coordination of all designs by three other bridge design consultants and consistent design processes for 38 bridges.

Pro-active coordination and innovative design processes and solutions make this a hallmark project. Since completion, this new roadway has alleviated much of the heavily congested urban area near the border.
