Oklahoma State Highway 77H - History

History

State Highway 77H was originally commissioned on 1950-01-11, running from Hollywood in Cleveland County to the Oklahoma County line. This original iteration of SH-77H was decommissioned less than two years later, being removed from the state highway system on 1951-11-05

SH-77H was returned to active service on 1955-02-07. This time, the highway began at the corner of Porter Avenue and Robinson Street in Norman and travelled north to the previous SH-77H's southern terminus at Hollywood. On 1959-02-27, the Department of Highways assumed maintenance of Sunnylane Road south of S.E. 29th Street (at that time part of SH-3), adding it to SH-77H. This made all of the old SH-77H part of the new SH-77H, and extended the highway's northern terminus into the Oklahoma City suburb of Del City. On 1977-06-06, the highway was extended further north into Del City along Sunnylane Road to Reno Avenue, where it turned west, ending at US-77 (which followed Lincoln Boulevard at the time).

On 1988-12-12, SH-77H was removed from Sunnylane Avenue and Porter Avenue and redesignated one section line east onto Sooner Road and 12th Avenue. At the same time, it was truncated to I-240 in Oklahoma City, and its southern terminus became the 12th Avenue–Classen Boulevard intersection in Norman. Before this rerouting, SH-77H served as SH-37's eastern terminus, but when SH-77H was moved, SH-37 was not extended to meet the new alignment. Thus, SH-37 still ends at Sunnylane Road, one block short of SH-77H.

In April 2009, US-77 was realigned through Norman. The portion of 12th Avenue between Classen Boulevard and Tecumseh Road became part of US-77. This change shortened SH-77H by 4.7 miles (7.6 km), and brought its terminus to the present-day location of the 12th Avenue–Tecumseh Road intersection.
