Pennsylvania Route 341 (PA 341) is a state highway in the U.S. state of Pennsylvania. The route runs 10.7 miles (17.2 km) from PA 230 in Londonderry Township in Dauphin County east to PA 241 in South Londonderry Township in Lebanon County. The route is a two-lane undivided road known as Colebrook Road for its entire length, passing through rural areas. Along the way, PA 341 crosses PA 743 near Deodate and passes through Upper Lawn. An eastbound truck route, PA 341 Truck, bypasses the route between PA 230 and PA 743. PA 341 was first designated onto its current alignment by 1930, running between U.S. Route 230 (US 230, now PA 230) and PA 241. The route was fully paved in the 1930s. Between the 1930s and 1940s, PA 341 headed southeast along Lawn Road to end at PA 241 in Lawn.
