US Route 6

U.S. 6 crosses the state line and shares the same Borman Expressway with Interstate 80/94 through Hammond and Gary until State Road 51 Exit 15; it goes south for about 2 miles and turns east until it meets U.S. Route 421 in Westville, then goes south for a mile then east until it meets U.S. Route 35 and U.S. Route 31, and it shares the same road with U.S. Route 33 for about 5 miles until U.S. Route 33 breaks south toward Fort Wayne, IN at Ligonier, IN, and then it is mostly two lanes through Indiana until it meets the Ohio state line just east of Butler, Indiana. Before the Borman Expressway was completed, U.S. 6 was on Ridge Road, portions of which are now signed Business U.S. 6.
