Dallas High Five Interchange


The $288 million Dallas High Five Interchange project is a five-level interchange at the intersection of US 75 and IH 635, two of the busiest highways in North Texas, with a daily traffic count of 500,000 vehicles per day. The plans for the new interchange included 43 bridges, 710 columns, a total of 10 main lanes and four barrier-separated high-occupancy lanes on I-635, a total of eight main lanes on US 75, and a reversible high-occupancy lane connecting the two highways. TxDOT’s largest project at the time, the Dallas High Five Interchange improved driver safety, air quality, and local access. It also increased traffic capacity and provided flexibility to meet future growth.
