An example of this is the concurrency of Interstate 70 (I-70) and I-76 on the Pennsylvania Turnpike in western Pennsylvania. I-70 merges with the Pennsylvania Turnpike so the route number can ultimately continue east into Maryland; instead of having a second physical highway built to carry the route, it is combined with the Pennsylvania Turnpike and the I-76 designation. A triple Interstate concurrency is found in Wisconsin along the section of I-41, I-43, and I-894 in Milwaukee, Wisconsin. The concurrency of I-41 and I-43 on this roadway is an example of a wrong-way concurrency.
