Brookfield Police are warning about construction in the Town Center area starting tomorrow.  Drivers are cautioned to expect heavy delays in the Four Corners Friday and Monday.  Milling of the existing roadway and paving of the new road surface will reduce the majority of this area down to one lane. Access to all businesses in this area will remain open, but Brookfield officials are asking that through traffic avoid the area to reduce congestion and increase work zone safety.  Milling and paving will start at 7am and end at approximately 3pm on both days.
