Overview
The Southern Gateway project was a $666 million design-build construction project by TxDOT, aimed to rebuild and widen Interstate 35E (I-35E) south of downtown, as well as widen US 67 between I-35E and I-20 and the I-35E/US 67 split. The purpose of the 11-mile project was to improve safety issues, provide congestion relief, support traffic operations, address roadway deficiencies and improve system linkage.
The improvements also consisted of constructing reversible non-tolled express lanes, lanes that are open to all users including SOVs (single occupancy vehicles) and HOVs (high occupancy vehicles), and/or general purpose lanes to improve capacity in the corridor. Construction began in early 2018 and completed winter 2022.
Project facts
I-35E in the Southern Gateway corridor was consistently ranked as one of the most congested roadways in Texas according to the Texas A&M Transportation Institute.
About 192,000 vehicles travel through southern Dallas County each day.
The project was partially being funded by the Texas Clear Lanes Initiative.
The project included building structural elements and accommodations for the City of Dallas’ planned deck plaza between Ewing and Marsalis Avenues. The overall design and amenities of the deck plaza were managed by the City of Dallas. Any inquiries regarding the deck plaza will be redirected to the City of Dallas.
