Interstate 235 (abbreviated I-235) in Oklahoma is also known as the Centennial Expressway. The spur route of Interstate 35 is a 5.4-mile-long north–south spur route in central and north-central Oklahoma City. It connects northbound to U.S. Highway 77 on to suburban Edmond and southbound at Interstate 44 on to Interstate 35 and Interstate 40 at downtown Oklahoma City. U.S. Highway 77 is concurrent with I-235 for the entire route.[5] South of its junction with I-40, I-235 becomes Interstate 35.

Route description[edit]

I-235's route forms the eastern edge of Automobile Alley, the Deep Deuce urban residential neighborhood, and the Bricktown Entertainment District, all of which are in the eastern section of downtown Oklahoma City.

History[edit]

The I-235 designation was approved by the American Association of State Highway and Transportation Officials (AASHTO) on July 13, 1976.[6] Only 3.66 miles (5.89 km) were complete in 1978.[7] It finally opened in 1989.[8]

Interstate 235 in Oklahoma officially finished a major reconstruction in September 2008, which changed the section of I-235 between N.W. 50th Street, on the north end, and N.W. 23rd, on the south end. It added a third lane and an exit lane, changing the two-lane stretch into four lanes.

Exit list[edit]

The entire route is in Oklahoma City, Oklahoma County.
