TXDOT I-10 widening

The Interstate 10 West of Snake Creek to Mason Road WA #1 project involves the widening of IH-10 to add two diamond and two general-purpose lanes as well as redesigning the Pin Oak intersection to elevate I-10 over Pin Oak Road. The project will improve traffic flow and safety in the region. The design accounts for installing six traffic signals, high-mast lighting, temporary signals as needed, and intelligent transportation system (ITS) components; adding closed-circuit television (CCTV) cameras; and replacing fiber-optic cable. Woolpert is also focusing on optimizing signalization, illumination, and ITS infrastructure to support the expanded lanes and improved roadway function.

The widening project faces challenges with limited right of way (ROW), which restricts the available space for placing traffic signal equipment, light poles, and ITS infrastructure. Additionally, the team is overcoming the logistical complexities of coordinating with other engineering firms and utility companies to avoid conflicts with existing utilities in a densely developed area.

To overcome the challenge of limited ROW, Woolpert and the Texas Department of Transportation (TxDOT) will work closely with utility companies and engineering firms to identify opportunities for consolidating utility routes or sharing trenches, which will reduce spatial conflicts. For traffic signal and lighting equipment, alternative pole foundation designs will be considered that can fit within tighter spaces while maintaining structural integrity. Additionally, frequent coordination meetings with all parties will make sure that potential conflicts are identified early and addressed in a timely manner. By streamlining the planning process and using innovative solutions, such as pole sharing or compact foundation designs, Woolpert will help TxDOT successfully implement the project within the constraints of limited ROW.
