Water Main Break Opens Sinkhole in Smithtown

A water main break opened up a good sized sinkhole somewhere in town this week, and crews have been out working to get it patched and the road stable again. These things tend to show up fast, a section of pavement gives way once the ground underneath washes out, and then it is a matter of shutting off the line, draining the area, and rebuilding what is under the street before anyone can drive over it again.

I do not have the exact road or how long repairs will take, so for the details on location and timing, News12 New Jersey has the full report on the Smithtown sinkhole.

Old water mains under Long Island roads do this from time to time, and it is a good reminder that a lot of the infrastructure holding up our streets and driveways is older than most of us realize. If you are curious how the area around any particular block is doing, or just want to see what is happening street by street, take a look at /towns/ for a broader view of Smithtown.
