Leap-The-Dips is a wooden roller coaster located at Lakemont Park near Altoona, Pennsylvania. Constructed in 1902 by the Federal Construction Company and designed by E. Joy Morris, it is the oldest operating roller coaster in the world and believed to be the last surviving side friction roller coaster of the figure-eight variety. Leap-the-Dips operated continuously until 1985, when it closed after falling into disrepair. A fund-raising campaign led to its restoration, with refurbishment efforts beginning in 1997 and ending with a grand-reopening in 1999. It was designated a National Historic Landmark in 1996 and received the Coaster Classic and Coaster Landmark awards from American Coaster Enthusiasts.
