BOUND BROOK - The Raritan River has spilled over its banks in Manville, flooding Duke's Parkway Island Park and some surrounding roads.
In Bound Brook, floodwaters reached halfway up the pumps at a gas station and mingled with the gas, creating a murky mess.
Conditions have improved, but roads in some areas remain impassable or closed.
Video from Chopper 12 showed dozens of vehicles submerged in a large car lot.
Residents in this flood-prone area were surprised the water levels rose as high as they did
