Schuylkill Expressway

The Schuylkill Expressway /ˈskuːkəl/, locally known as "the Schuylkill", is a freeway through southern Montgomery County and the city of Philadelphia. It is the easternmost segment of Interstate 76 (I-76) in the U.S. state of Pennsylvania. It extends from the Valley Forge interchange of the Pennsylvania Turnpike in King of Prussia, paralleling its namesake Schuylkill River for most of the route, southeast to the Walt Whitman Bridge over the Delaware River in South Philadelphia. It serves as the primary corridor into Philadelphia from points west. Maintenance and planning for most of the highway are administered through Pennsylvania Department of Transportation (PennDOT) District 6, with the Delaware River Port Authority (DRPA) maintaining the approach to the Walt Whitman Bridge.

Constructed over a period of 10 years from 1949 to 1959, a large portion of the expressway predates the 1956 introduction of Interstate Highway System; many of these portions were not built to contemporary standards. The rugged terrain, limited riverfront space covered by the route and narrow spans of bridges passing over the highway have largely stymied later attempts to upgrade or widen the highway. With the road being highly over capacity, it has become notorious for its chronic congestion. An average of 163,000 vehicles use the road daily in Philadelphia County, and an average of 109,000 use the highway in Montgomery County, making it the busiest road in Pennsylvania. Its narrow lane and left shoulder configuration, left lane entrances and exits (nicknamed "merge or die"), common construction activity, and generally congested conditions have led to many accidents, critical injuries, and fatalities, leading to the highway's humorous nickname of the "Surekill Expressway" or, in further embellishment, the "Surekill Distressway" or the "Surekill Crawlway".
