Stevens Run[1] (Stevens Creek,[2] Tiber) is a 2.2-mile-long (3.5 km)[3] tributary of Rock Creek in Pennsylvania in the United States.
Within the borough the stream is in a concrete channel, including a covered portion.
From 1884 to 1942, the run was spanned by three bridges of the Round Top Branch railroad.
[5] Samuel Gettys' Tavern was located on the south side on the uphill slope of the now-named Stevens Run, and Rock Creek Church was approximately on the north bank of the now-named Carlisle Street and Stevens Run.
[6] In 1902, a new bridge was built over the Tiber on Chambersburg Street.
