 Also not up to full Interstate Highway standards prior to 1967 was a section in the vicinity of Lindsey Street in the southern portion of Norman where another at-grade intersection still existed which dated back to the original highway's construction in the early 1950s—this was also brought up to full Interstate Highway standards in 1967 with the construction of interchanges on I-35 at Lindsey and a short distance to the south for the future SH-9 bypass that would be built around the south side of Norman in the early 1970s.Further south, I-35 was completed from Marietta south to the Red River bridge in 1963, at which point a nearly gap of uncompleted interstate would exist between Purcell and Marietta until the late 1960s with traffic continuing to be routed over paralleling US-77.This was in large part due to efforts of the towns of Wynnewood, Paoli, and Wayne, fighting to keep I-35 as close as possible to US-77.
