Completion of the I-244 bridges in 1967 removed most vehicular traffic from the 11th street bridge. In 1980, it was closed to traffic, although it remained open to pedestrians. In 1996, it was added to the National Register of Historic Places. In 2004, the City of Tulsa, Oklahoma, formally renamed the Eleventh Street Bridge (which carried US 66 over the Arkansas River), the Cyrus Avery Route 66 Memorial Bridge in honor of the man who vigorously promoted the creation of Route 66."Cyrus Stevens Avery Timeline" .
