The proposed improvements include constructing a grade separation at Loop 1604 and Marbach Road in order to improve safety and operations at this intersection. The project includes the construction of one lane in each direction on Loop 1604 that would overpass Marbach Road. This lane would diverge from the existing lanes, overpass Marbach Road and then merge with the existing lanes once beyond the intersection.

The two directions of traffic on the overpass would be separated by a traffic barrier and necessary shoulders would be constructed. The grade separation would be constructed between the existing lanes of traffic leaving the existing at-grade intersection in place.
