Route 18, Boyd Park and the Riverfront
Route 18 runs along the river, with Boyd Park between the road and the water. When the Raritan runs high, it can spill onto the highway. After Ida, Route 18 stayed closed until September 4, 2021. Townhouses and apartments along Route 18 tend to take damage when that happens, and signs on John Street Extension and Riverside Drive tell people to move their cars to higher ground in heavy rain, because the storm drains fill fast and garages take on water.
