Slice of Seaport sidewalk selling for nearly $2 million

In the ever-more-expensive Seaport district, even the sidewalks can come at a steep price.

Developer Jon Cronin has reached a deal with the City of Boston to buy about 3,000 square feet of the city’s sidewalk outside two waterfront bars he owns — for $1.95 million.

That may sound outrageous for a modest patch of concrete — even in a town where parking spaces can sell for more than $300,000 — but Cronin didn’t have much choice. Without the tiny triangular-shaped plot, the developer won’t have enough space for a $260-million luxury condo tower he wants to build at 150 Seaport Blvd., on the site of the Whiskey Priest and Atlantic Beer Garden bars.
