I-35 from US 79 to SH 45 North (southbound)

Overview

The project includes constructing an auxiliary lane to remove merging conflicts on the I-35 southbound mainlanes between RM 620 and Hesters Crossing. The proposed southbound auxiliary lane extending from the US 79 entrance ramp to the SH 45N exit ramp will eliminate a forced merge. The existing southbound auxiliary lane from the RM 620 entrance ramp to the Hesters Crossing exit ramp will remain. There will be no construction on the frontage roads or changes to ramp locations.
