The eastbound on- and off-ramps at the Ewing Road interchange of Business Loop 376 in Moon were reopened today.
A roundabout has been built at the interchange to improve traffic flow. The $950,000 project, sponsored by the Allegheny County Airport Authority, began in late June.
A roundabout is a modern version of the traffic circle. It has no signals or stop signs and traffic flows continuously, with drivers entering the roundabout yielding to those already in it. According to PennDOT, roundabouts have been shown to reduce fatal crashes by 90 percent and crashes with injuries by 75 percent. They are able to handle 30 percent more traffic volume than standard intersections.
"Our Moon Township drivers are going to be very pleased with its results," township manager Jeanne Creese said at a ribbon-cutting ceremony this morning.
"It's a key to economic development in this area," said Dan Cessna, PennDOT district executive. "They're preparing for the future."
It is the second roundabout to debut in Western Pennsylvania this year. Rochester in Beaver County opened one in July. Two roundabouts are part of the Westinghouse campus in Cranberry.
