Heads up, commuters! Bridge rehab work on the much-used interchange of SB I-435 and SB U.S. 169 in Clay County is scheduled to shake things up a bit on the roads. The Missouri Department of Transportation (MoDOT) announced that starting Tuesday through Thursday road work will disrupt the usual flow of traffic.

Those of us accustomed to the convenience of zipping along the U.S. Route 169 to I-435 might have to pad our schedules as MoDOT puts drivers on notice for possible delays. From 8 am until 3 pm each day, the ramp (loop) from SB U.S. 169 to SB I-435 will be closed, and the SB I-435 right lane at the U.S. 169 interchange won't be available for your rubber to hit the road. With fewer lanes on deck, traffic could get snug, so keep an eye on the clock when planning your drive.

MoDOT reminds everyone that driving through work zones demands extra caution. Slow down, keep distractions at bay, and be ready for unexpected detours or slowdowns. Remember, work zones don't have a one-size-fits-all look – they can range from temporary barricades for quick fixes or debris clearance to more enduring stretches with lane closures.

For updating your navigation apps or perhaps, plotting an old-school map detour, all bridge rehabilitation activities hinge on cooperating weather conditions. So while the schedules are set, commuters know to expect the unexpected. And as we cling to the hope of hindrance-free highways, patience will be as crucial as your GPS.
