Transportation

It’s about more than just the destination. It’s about designing roads and bridges that are built with safety in mind to ease congestion, create enhanced mobility, and provide traveling options. It’s about minimizing construction impacts to the traveling public. It’s about being engaged in the communities where our projects are located. And, it’s about integrating innovative engineering that aligns with the future of transportation and roadway technology. Our 48 years of success in the realm of transportation has taught us that it is an ever-evolving infrastructure. The knowledge of our seasoned engineers is enhanced by the best and brightest young engineers who excel at 3D simulations and traffic modeling. With these essential tools in place, we continue to build our experience in every facet of the comprehensive planning, design, and cutting-edge technology that drives transportation and keeps people on the move where they live, work, and play. We are TxDOT pre-certified and LGPP (Local Government Project Procedures) certified. LJA Transportation staff has worked on projects in all 25 TxDOT Districts.
