Pennsylvania Route 770 Truck is a 13-mile-long (21 km) truck route bypassing a segment of PA 770 where trucks over ten tons are prohibited in McKean County. It begins at the PA 770 terminus in Lafayette Township.^[5] It ends at PA 770 in Bradford Township.

The route is an oddity, as it is longer than its main route (PA 770) by one mile,^[4] and that its only signed as such westbound, instead of both directions.^[6] The entire route follows PA 59 on its western end, and US 219 on its eastern end.^[4]
