HNTB served as lead designer and provided public involvement and construction engineering support for the El Paso District of the Texas Department of Transportation on this important urban corridor in west Texas.

Issues with congestion and incident management led TxDOT to identify this segment of Interstate 10 as a priority. The freeway averages approximately 120,000 vehicles per day. A network of collector-distributor lanes and interchange improvements was identified to address the needs.

To meet the accelerated delivery schedule, HNTB designers had to fit the improvements into this developed freeway corridor and minimize right of way acquisition. HNTB offices throughout Texas collaborated to successfully deliver the challenging and complex design in an eight-month timeframe. Services included the design of 29 bridges, 35 retaining walls and four urban interchanges with direct connectors.
