U.S. Route 11 or U.S. Highway 11 (US 11) is a major north–south United States Numbered Highway extending 1,645 miles (2,647 km) across the eastern U.S. The southern terminus of the route is at US 90 in Bayou Sauvage National Wildlife Refuge in eastern New Orleans, Louisiana. The northern terminus is at the Rouses Point–Lacolle 223 Border Crossing in Rouses Point, New York. The route continues across the border into Canada as Route 223. US 11, created in 1926, maintains most of its original route. The route north of Knoxville, Tennessee, follows a route similar to Interstate 81 (I-81). While it is signed as a north–south route, it physically travels in a northeast–southwest direction.
U.S. Route 111 (US 111) was a U.S. Highway that extended from Baltimore, Maryland north to the Harrisburg, Pennsylvania area. It replaced part of the Susquehanna Trail, partially signed as Pennsylvania Route 4, and was in turn replaced by Interstate 83 (I-83). Portions of its pre-freeway alignment are now Maryland Route 45 and I-83 Business. Other old sections in Pennsylvania are now unsigned Quadrant Routes or township-maintained roads. US 111 extended north to the Pennsylvania–New York state line where U.S. Route 15 now crosses it between 1928 and 1937.
