Collin County ranks as one of the top growth areas in the state and the nation. Since the 2000 census, the county's population grew more than 52 percent by 2009, including massive private and commercial development. In that light, Collin County officials continue to evaluate and prepare for the next major outer-loop thoroughfare.

In December 2002, Collin County initiated the Outer Loop Alignment Study to develop various alignments within and along a 3,000-foot-wide corridor. The study identified a locally preferred alignment in order to determine right-of-way needs for the road to be built when the time comes.

Most recently, Commissioners approved contracts with local engineering firms to refine the technically preferred alignment and finalize the engineering design of several segments of more than 50 miles of Collin County’s portion of the regional outer loop.
