Mercer County Landfill

Mercer County Landfill sits on Frontage Rd in Princeton and is the local spot for burying municipal and commercial refuse. Neighbors bring household junk, contractors drop construction debris, and big trucks come through for larger loads. It's the county landfill-big, practical, and not fancy.

There's a gate/booth area where vehicles queue up and a scale that most drivers cross - tipping fees are weight-based at landfills like this, so expect to stop on the way out as well. The site looks like a working dirt operation: graders, berms, and a working face where loads get dumped, with trucks and trailers moving in and out. Commercial haulers are handled here too, but they usually face different fees than residential users. Lines build up on weekends and during spring cleanup, so timing matters if trying to avoid a wait.
