About the Southern Gateway Project

The Southern Gateway Project is a $666 million design-build construction project by the Texas Department of Transportation (TxDOT) aimed to rebuild and widen I-35E south of downtown Dallas, as well as widen U.S. 67 between I-35E and I-20 and the I-35E/U.S. 67 split. Construction will also include building two reversible non-tolled express lanes. The goal of the 11-mile project is to improve safety, provide congestion relief, address roadway deficiencies and improve system linkage. Construction began in early 2018 with an anticipated completion of late 2021. The Southern Gateway Project is part of the Texas Clear Lanes initiative by TxDOT to address growing traffic congestion in the state.
