I heard it too, woke me up from a sound sleep. I suspect it's the wind tunnel that you can see as you drive down Rt. 291 towards Chester.

Well if that's the case they need to do it during the day when we are not asleep. Thanks for the comment.

I'm glad I wasn't the only one that heard it, I thought I was going crazy.

Ivee heard the noise as well for the past 2 nights and im in Norwood. Sounded like a street cleaner, I lived in LA yrs ago and thats when the city would clean the streets.

Exactly! Isn't this something that could be done during the day? I mean why at night when people are trying to sleep? Ugh!

It's resolved.
