Work on the $1.4 billion expansion and upgrade to Interstate 35E north of Dallas launched this month with a groundbreaking ceremony on the shores of Lewisville Lake.
The 35Express project extends 28.2 miles from I-635 in Farmers Branch to U.S. 380 in Denton, crossing eight cities in Dallas and Denton counties. Work is slated to begin by the end of the month and completion is slated for 2017.
