A 12-inch water main break is causing traffic disruptions and water service issues in East Brunswick. Crews are working to repair the break near Old Stage Road. Officials say one lane of Old Stage Road remains open between Fern Road and Pawnee Road, though access appears to be limited primarily to local traffic due to roadblocks in the area. Some residents may notice low water pressure as repairs continue. Officials also say customers experiencing discolored water should run cold water and flush toilets, which may help clear the issue. Residents are being advised to avoid doing laundry until repairs are completed. There is no official estimate for when the work will be finished, though crews at the scene indicated repairs could continue through at least late Tuesday morning.
