91st Street closure causes traffic troubles and last updated 2021-07-09 09:20:01-04 TULSA, Okla. â 91st Street in Tulsa is partially closed after the ground underneath the asphalt collapsed. The road is to one lane and it is giving drivers a headache. "We're kind of on an island here," Kimberly Vining said. Vining and her Thousand Oaks neighbors are going out of their way just to find their way home. "I've found some creative new ways to get to my house, for sure," she said. The eastbound lane on 91st Street from Harvard Ave. to Quebec Ave. is closed. City of Tulsa traffic crews shut the lane down after a sinkhole swallowed up part of the road.
