Section 1
LOCAL CASE STUDIES
PennDOT is incorporating roundabouts in projects throughout the Engineering District 12-0 region of Fayette, Greene, Washington and Westmoreland counties in western Pennsylvania.

Line Airport

Route 981 at the Arnold Palmer Regional Airport,
Westmoreland County
This roundabout opened to traffic in fall 2017. This single lane roundabout will serve as the intersection of Route 981 and the new airport entrance after that connection is completed by the Westmoreland County Airport Authority. This roundabout design will be similar to the roundabouts proposed for Section 1 of the LVTIP.

Line New Stanton

New Stanton I-70 Interchange,
Westmoreland County

The new interchange at New Stanton on Interstate 70, which includes three roundabouts, opened to traffic in February 2017. All three are single-lane roundabouts offering seamless movement from the I-70 interchange throughout the local roadway network.

Line

Route 519,
Washington County

Two, dual-lane roundabouts on Route 519 near Eighty-Four, PA opened in 2015. These roundabouts were implemented to improve safety at two closely spaced intersections.
