Interstate 235 (I-235) in Oklahoma is also known as the Centennial Expressway or the I-235 Central Expressway. The spur route of I-35 is a 5.4-mile-long (8.7 km) north–south alignment in central and north-central Oklahoma City. It connects northbound to U.S. Highway 77 (US-77) to suburban Edmond and southbound at I-44 on to I-35 and the I-40 Crosstown Expressway near downtown Oklahoma City. US-77 is concurrent with I-235 for the entire route. South of its junction with I-40, I-235 becomes I-35.
