PA 970 once extended further south into Clearfield County and western
Centre County. Its former southern terminus was at
PA 350 in
Sandy Ridge. It traveled northwest along present-day SR 3049 into
Osceola Mills. In Osceola Mills, PA 970 ran along Curtin Street to
PA 53 (Stone Street), turned left onto PA 53 forming a
wrong-way concurrency with it along Stone Street and Sarah Street until leaving the concurrency by making a right onto Elizabeth Street. The designation followed Drane Highway and Salem Road north through
Decatur and
Boggs Townships. Prior to 2002, PA 970 turned left onto Salem Road following present-day SR 2049 to Bigley, SR 2030 west to Woodland, and SR 2049 north to US 322 at its present southern terminus. After 2002 but before its truncation to Woodland, PA 970 traveled east along Link Road (SR 2034 and SR 2029) to US 322 outside of
Wallaceton. PA 970 then turned left onto US 322 following it northwest to its present southern terminus near Woodland. ==Major intersections==
