This photo, taken by VRX Senior Environmental Inspector Kyle Hill, shows heavy machines being prepped to set the new northbound frontage road railroad bridge on the US75/PGBT project. The new Plano Parkway Bridge over US 75 had just been completed. The railroad bridge spans were set in single pre-built sections over both the north- and southbound U.S. 75 frontage roads. The railroad remained active, and all work activity was time-sensitive. All of the excavation, embankment, shafts, columns, concrete, and R/R work was performed with the railroad line active, using scheduled and short train delays. VRX provided environmental compliance management for all facets of the project.

VRX, Inc. served as a subconsultant for the prime Construction Engineering and Inspection (CEI) firm. VRX provided weekly environmental inspections and auditing for this $37.5M expansion and interchange improvements at U.S. 75 at President George Bush Turnpike (PGBT) to Park Boulevard in Collin County.

Our scope for this project also included environmental compliance and regulatory services, including permit application preparation and compliance assistance for Texas Pollutant Discharge and Elimination System (TPDES); Spill Prevention Control and Countermeasure (SPCC) and Storm Water Pollution Prevention Plans (SWPPP); and audits/reviews.

Construction included:

• Widening the main lanes and ramps of U.S. 75
• Constructing the Kansas City Southern railroad bridges with an active track over both the northbound and southbound main lanes and ramps of U.S. 75
• Demolishing the Plano Parkway bridge and constructing an 8-lane bridge with U-turns
• Constructing Mechanically Stabilized Earth (MSE) walls
• Widening the 15th street bridge over U.S. 75
• Constructing an elevated direct connect bridge from 15th street to U.S. 75
