TULSA, Oklahoma - City crews are working to repair a broken water main on North Memorial between Interstate 244 and Latimer. They have been at work since about 3 a.m. Friday.

Workers say it's an older, 12-inch line and that no residential customers are without water.

The line is about 6 feet deep.

The repair work is affecting traffic as northbound Memorial has been narrowed to one lane north of Interstate 244. They expect the repair to be complete by about noon Friday if there are no further problems.
