I-35 from US 79 to SH 45 North

Overview:

The project includes constructing braided ramps to remove merging conflicts on the I-35 northbound mainlanes between Hesters Crossing and RM 620. The northbound extended entrance/exit lane will allow drivers to match travel speeds prior to merging. The northbound and southbound frontage road intersections at I-35 and US 79 will also be reconstructed and a third left-turn lane for westbound US 79 will be added.
