Penberthy Road Extension
Client: City of College Station
Project Cost: $3.4 Million
Service: Civil Engineering, Design
Practice: Construction Services, Municipal & District Services, Surveying
Location: College Station, Texas
A unique challenge for this project was the need to maintain ongoing access to the Texas A&M equestrian operation that was segregated by the new roadway. Also, significant earthwork was needed.
To address access to the equestrian operation, we devised a solution that included a depressed livestock crossing that facilitates livestock movement under Penberthy Road during all weather conditions. The livestock crossing design provided a significant earthwork balancing challenge that required 3D modeling and extensive coordination with the grading and drainage plans to balance the earthwork portion of the project.
Jones|Carter was the prime design consultant for the Penberthy extension from Luther Street to George Bush Drive (FM 2347). The scope included a 4-lane major collector roadway which transitioned to a 5-lane approach with a dedicated left turn lane at the intersection with FM 2347. The intersection included a traffic signal addition. The professional services included plans, specifications, estimates, topographic surveying, geotechnical investigation, environmental clearances, traffic signal warrant study and design, FEMA level flood plain study, and construction phase services.
The extension crossed the main channel of Whites Creek and one of its tributaries. A single-cell box culvert was designed for the tributary crossing, and a precast concrete arch span bridge was designed for crossing the main channel of Whites Creek. Both drainage crossing structures were designed based on the FEMA level flood plain study performed by Jones|Carter.
