State Route 276 is a state highway in remote portions of San Juan County, eastern Garfield County, and Kane County, in the southeast of the U.S. state of Utah. The route is used as an access to Lake Powell, serving the small resort towns of Ticaboo and Bullfrog. Historically, SR-276 crossed Lake Powell via the Charles Hall Ferry (originally called the John Atlantic Burr Toll Ferry), the only auto ferry in the state of Utah; however, the ferry is currently out of service due to low water levels. The entire route is part of the Trail of the Ancients National Scenic Byway. Lake Powell separates the route into two sections; the eastern section was numbered State Route 263 prior to the existence of the ferry.
