context_page_description: Interstate 79 is an Interstate Highway in the eastern United States, designated from I-77 in Charleston, West Virginia to Pennsylvania Route 5 and PA 290 in Erie, Pennsylvania. It is a primary thoroughfare through western Pennsylvania and West Virginia, and makes up part of an important corridor to Buffalo, New York, and the border with Canada. Major metropolitan areas connected by I-79 include Charleston and Morgantown in West Virginia, and Pittsburgh, and Erie in Pennsylvania.
  In West Virginia, I-79 is known as the Jennings Randolph Expressway, named for Jennings Randolph. In the three most northern counties it is signed as part of the High Tech Corridor. For most of its Pennsylvania stretch, it is known as the Raymond P. Shafer Highway, named for Raymond P. Shafer.
context_section_description: I-79 enters Pennsylvania after leaving West Virginia University in Morgantown, West Virginia. South of Washington, Pennsylvania, I-79 traverses the mostly rural Greene County area.
  Between mile markers 34 and 38, I-79 is multiplexed with I-70 in the Washington, Pennsylvania area before heading north towards Pittsburgh.
  The freeway into Pittsburgh requires drivers to use I-376 while I-79 completely bypasses the city. Beyond the Pittsburgh area, I-79 traverses more rural areas in Butler, Lawrence, Mercer, Crawford, and Erie counties before arriving at its termination point in Erie. In Erie, I-90 provides an important connection from I-79 to Buffalo, New York and the border with Canada.
  Around the 100-mile marker on the northbound side are two ghost ramps that were specifically built for the Boy Scouts of America in order to have access to Moraine State Park without having to get on U.S. Route 422 for the 1973 and 1977 National Scout Jamborees, which were held at Moraine. The ramps were permanently closed after the 1977 event, but remain in place as of 2017.
  I-79 was completely re-built in the Pittsburgh area in the early 1990s.
