I-35 Northeast Expansion (NEX) South Project

Improving Mobility and Safety through Strategic Design-Build

The I-35 Northeast Expansion (NEX) South Project is a significant infrastructure development aimed at improving safety, mobility, and congestion management along a critical 4-mile stretch of I-35 in Texas. This project, part of TxDOT’s 2023 Unified Transportation Program, involves the addition of three elevated express lanes, including two non-tolled general-purpose lanes and one non-tolled high occupancy vehicle lane, along with direct connectors at I-410 South.

Atlas Technical Consultants serves as the Professional Services Quality Assurance Firm (PSQAF) and Independent Quality Firm (IQF) for the Fluor/Austin Bridge Design-Build Team, also known as Lone Star Constructors. We are spearheading a comprehensive Quality Assurance (QA) program to ensure all services comply with federal and state standards. Our scope of work includes rigorous review of work submittals, audits, and independent QA material testing and inspections.

By managing this QA program, Atlas is helping to ensure that the I-35 NEX South Project not only meets but exceeds the stringent safety and operational standards set forth by TxDOT, ultimately contributing to a more efficient and safer transportation corridor.
