MOUNTAINSIDE, NJ - A water main break at Mill Lane in Mountainside, right off of Route 22, is causing heavy delays for Monday's rush hour commuters and others driving in the area.

The eastbound lane of Route 22 is closed in Mountainside in the area of the Spanish Tavern and L'Affaire restaurants. According to Union County officials, delays could continue in the area for "four to eight hours," which would possibly leave the highway closed until after midnight.
