 During the 1960s , plans developed to widen U.S. Route 15 for safety precautions . Construction progressed fast , reaching the Lycoming County line in 1968 . At the time , Route 287 terminated at an intersection with U.S. Route 15 at the Hammond Reservoir . Ten years later , Route 15 was completed up to Tioga , and that year , the Pennsylvania Department of Transportation extended Route 287 to the new interchange . At that point , U.S. Route 15 followed the northernmost alignment of PA 287 to Lawrenceville . This interchange was completed in late 2000 with an opening ceremony by then @-@ governor Tom Ridge .
