Heads up, St. Peters commuters: Missouri American Water is on the scene along Mid Rivers Mall Drive just south of Grand Teton Drive tackling a water main repair today. If you're hitting the road, be prepared to tighten up; there's a lane closure in both directions as the crew gets down to business.

While the repairs are underway, the local authorities have rolled out a strategy for drivers: the zipper merge. By taking turns at the merge point, traffic backups should shrink significantly. But, caught by the closure, some northbound travelers might find a single lane shut down for an extended stretch during road repairs.

Looking for the lowdown on the traffic shake-up? StPetersMO mobile app users can snag real-time updates. Just grab the app, and with a tap on the gear icon, you can opt in for all the latest notifications on the project's progress.

For those without the app, updates come standard on the City of St. Peters' website, where the official statement notes, "Please follow the warning signs and drive carefully through the work area." And for motorists needing a quick primer on executing the perfect zipper merge, the SPTVnow.net video is a must-watch.
