PROJECT COST: $220,000,000
Segment 4 - also known as the Sam Rayburn Tollway/U.S. 75 Interchange - is one part of the North Texas Tollway Authority SH 121 corridor from Farm-to-Market 423 to U.S, 75. Work includes new construction of a six-lane tollway on SH 121 and reconstruction of U.S. 75 to eight lanes.
The work allows for tolls to be collected using an electronic toll-collection system. Tolls can be paid via transponder units on the drivers' car windshields, or overhead sensors will scan license plates of cars without transponders and send their owners a monthly bill.
The project's general contractor set up three concrete recycling machines to crush old concrete and repurpose it. To date, Webber has recycled approximately 27,000 cu yds of concrete and 1.9 million lbs. of steel on this project.
