Job description

Who is NTE, NTE 35W, and LBJ?

North Tarrant Express (NTE) was the first design-build-finance-operate-maintain managed lanes project in Texas and consisted of the complete reconstruction of 13.3 miles of the existing I‑820/SH‑183 corridor between Dallas and Fort Worth. Since opening in October 2014, nine months ahead of the contracted completion date, the general highway lanes are experiencing a 70 % decrease in congestion time and a 15 % increase in average speed. This Cintra‑led project has doubled capacity and significantly improved mobility along this heavily congested corridor that traverses the heart of six cities through Northeast Tarrant County.

North Tarrant Express 35W (NTE 35W) project spans 16.8 miles from I‑30 in downtown Fort Worth to Eagle Parkway at the north end of Alliance Airport. The project is operated and maintained by the Cintra‑led consortium in North Texas. This project has improved mobility by adding additional road capacity through a combination of general highway lanes and continuous frontage roads, along with tolled express lanes that use variable pricing to keep traffic moving.

LBJ Express (LBJ) is currently the largest P3 operation in Texas and one of the largest ever undertaken in the U.S. It is a regionally‑significant transportation improvement project in North Texas that is relieving severe congestion in the dense urban area of north Dallas. In 2009, the Cintra‑led consortium was selected to complete the design, construction, finance, operation, and maintenance of the project along I‑635 and I‑35E. Since opening in September 2015, the general highway lanes are realizing a 60 % decrease in congestion time and a 10 % increase in average speed.
