If you're referencing the property across from the highway exit, I'm pretty sure it's owned by the state DOT. They've been sitting on it for years. That's part of the land reserved for the partially developed circumferential highway. The proposed completed highway gets periodically revived, designed to alleviate traffic on Lowell Rd. and to add another bridge over to RT 3 between Nashua and Manchester. Wonder if they'll ever give it up? Large issue with wetlands towards the east, also costs and eminent domain hassles, they might as well throw in the towel!
Notice driving off the highway and heading north on Lowell Rd., maybe a quarter mile past the Subaru dealer, there's a open plot on the left that's been available for years.
