Travelers will find the eastern-most terminus of Route 422 in King of Prussia, Pennsylvania, accessible from a number of major roadways in the area, including the Pennsylvania Turnpike, the Schuylkill Expressway, and U.S. Highway 202. This is a major interchange for the Turnpike, for it drops its I-276 signage heading west in favor of I-76 signage for the remainder of its trip across Pennsylvania. In the early 2000s, the entire interchange underwent a massive five-year reconstruction project that involved the construction of new ramps, the widening of all intersecting roadways, and much more. Several small businesses in the King of Prussia area were demolished as part of this project, and the nearby King of Prussia Mall shopping complex was also affected.
