The North Tarrant Express (NTE) project is a total highway reconstruction of the Interstate 820 (I-820) and State Highway 121/State Highway 183 (SH 121/SH 183, Airport Freeway) corridor between I-35W and Industrial Boulevard in Northeast Tarrant County, Texas. The NTE and the Texas Department of Transportation (TxDOT) anticipate the new highway system will relieve traffic congestion, improve safety on its roadways and have integrated plans for the anticipated traffic growth in one of the country’s fastest developing regions. When the improvements are completed, the $2.5 billion North Tarrant Express will have upgraded main highway lanes, continuous frontage roads, and 13.3 miles (21.4 km) of newly added tolled managed lanes (TEXpress Lanes).
