The same year a separate $3 million NJAW project replaced about 6,400 feet of aging main, 8 hydrants and 97 utility-owned service lines along Route 24 from Cherry Lane to Hilltop Road, and in early 2026 NJAW installed another 720 feet of 8-inch ductile iron on Mountainside Road between Ironia Road and Mountain Avenue..
