I-35 NEX Central

Rodriguez Engineering Laboratories LLC is serving as the Independent Quality Firm (IQF) for this $1.5 billion project.

The project

The Texas Department of Transportation is constructing approximately 9.5 miles of I-35 from I-410 North to FM 3009 in Bexar and Guadalupe counties, Texas.

The I-35 elevated lanes will provide direct connections to I-410 North and Loop 1604 West. The elevated lanes will provide one high occupancy vehicle (HOV) lane and two general purpose lanes in each direction. The project also includes incidental construction necessary to transition the elevated lanes and connectors with the existing highways including revisions to ramps and frontage roads and accommodations for drainage, utilities, signs, and other highway improvements.

Our Work

REL is currently the Independent Quality Firm (IQF) providing construction materials testing and inspection for the project.
