IRVING, Texas -- Originally designed in 1982 by Jay Morrish, with player consultants Byron Nelson and Ben Crenshaw, the TPC Four Seasons Las Colinas has been the host course for the AT&T Byron Nelson since 1986. Its contract with the PGA Tour event runs through 2018 before the tournament will move to Trinity Forest, a new course designed by Bill Coore & Ben Crenshaw that opened in 2017 south of Dallas.
In 2008, the TPC course was redesigned by former PGA Tour and current Champions Tour player D.A. Weibring and his partner, architect Steve Wolfard. The PGA Tour player consultant was Harrison Frazar; J.J. Henry also gave input as several holes were lengthened, and the 18th was dramatically redesigned. The golf course now plays to a par 70 and 7,166 yards from the championship tees.
