Pennsylvania 581 / Harrisburg Expressway

Although signage is sparse, Pennsylvania 581 constitutes the southwest leg of the Harrisburg "Capital Beltway." The Capital Beltway also utilizes Interstate 83 and Interstate 81, making an ellipse within the Harrisburg metropolitan area. Also of interest is that Pennsylvania 581 is one of a few state route freeways with exit numbers within the Commonwealth. Exit numbers are signed sequentially.

The Harrisburg Expressway saw reconstruction in the mid to late 1990s. The road work transformed the freeway from a substandard 1960s style expressway into a modern freeway with a concrete jersey barrier median, shoulders, and sound barriers.

Pennsylvania 581 scenes
Pennsylvania 581 heading west towards the terminus with Interstate 81. Although signed east-west, Pennsylvania 581 is actually headed north at this point.
