Interstate Highway 35E Corridor:
IH-35E is the principal transportation system that links Dallas to Austin and serves the cities of Lancaster and DeSoto located in Dallas County. The southern terminus, Parkerville Road, currently exists as a two-lane arterial. The northern terminus, IH-20, is an eight-lane controlled access freeway. There are several existing grade-separated interchanges along the corridor.
The existing four-lane freeway was upgraded to a six-lane section at Parkerville Road to a 10-lane section at IH-20. The existing bridges at Pleasant Run, Wintergreen and Danieldale did not allow for widening of the freeway and/or cross streets. Therefore, new structures were required at these locations and, in addition, new bridges were constructed at Belt Line Road and Ten Mile Creek. The new structures will allow for implementation of continuous turnarounds. Other design includes retaining walls, diamond interchanges, maintenance of traffic, temporary erosion control, hydrology and hydraulics, culverts, closed drainage system, signing and pavement markings.
