Interstate 235 (I-235) in Oklahoma is also known as the Centennial Expressway or the I-235 Central Expressway. The spur route of Interstate 35 is a 5.4-mile-long north–south alignment in central and north-central Oklahoma City. It connects northbound to U.S. Highway 77 to suburban Edmond and southbound at Interstate 44 on to Interstate 35 and the I-40 Crosstown Expressway near 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]

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.
