PennDOT is incorporating roundabouts in projects throughout PennDOT's Engineering District 12-0 region of Fayette, Greene, Washington and Westmoreland counties in western Pennsylvania.
Route 981 at the Arnold Palmer Regional Airport
This roundabout opened to traffic in fall 2017. This single-lane roundabout serves as the intersection of Route 981 and the new airport entrance. This roundabout design is similar to the roundabouts proposed for Section 1 of the LVTIP.
New Stanton I-70 Interchange
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.
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.
