Starting Sunday night, crews will close the northbound I-35 exit to FM 3009 in Schertz for three weeks to rebuild the exit ramps and finish work on the frontage road.
Traffic will use the Schertz Parkway exit and follow the frontage road to reach FM 3009.
Crews are rebuilding the exit to better align with the new entrance ramp from FM 1518.
An additional lane will be added to the exit. Work on the north-to-south turnaround should also be completed, opening the lanes of the northbound frontage road closed to accommodate the improvements at the busy intersection.
This closure represents the second major milestone on the project. The first major milestone is the construction of the exit ramp on northbound I-35 to Forum Parkway.
