Drivers could encounter some headaches along Highway 169 this weekend.
Crews are preparing to shut down two of the three southbound lanes at 46th Street North, which is also State Highway 266.
Crews have spent the past several weeks making improvements to the interchange.
At 7 p.m. Friday, two of the three southbound lanes will be closed until 6 a.m. Monday.
Drivers headed from Owasso to Tulsa should expect some delays.
