If Richmond airport is in a north traffic flow, we're under 2 approach paths. That's OK because they're slowing down anyway. If they reverse to a South flow, no noise because they have mostly climbed and turned toward their assigned headings.
I grew up in S Buffalo. We were there when they built I-90, late 50's, and I could hear the trucks at night, during the summer. That was great when I was a kid but now we're in another city, and very close to I-295, and that's a pain in the as*.
In S Buffalo, we were also under the Rwy 5 approach. Very similar situation. NE traffic flow, we could hear/see the planes, SW traffic flow no noise. In both locations we had some distant RR noise, but never a problem. Growing up in S Buffalo, there was always distant train noise.
