In a development project that's actually happening, construction is now proceeding at a snappy pace at the new mall going up where the old paperboard plant used to be on River Street, near the Mattapan line. And there's now a "coming soon" sign for a PriceRite supermarket. It'll join the Shaw's and Americas' Food Basket, both on Hyde Park Avenue, and the baby Stop & Shop on Truman Parkway.

Local 718 tweets a two-alarm fire broke out around 6 a.m. on the third floor of YMCA, 1137 River St. The Y is closed for renovation and expansion.

Boston Police shut down River Street near the Dorchester line around 11 a.m. when somebody discovered what appeared to be a live hand grenade. It turned out to be an inert training grenade.

If the neighborhood is Hyde Park, the answer is two. Both are on River Street; the New York one is in Cleary Square; the New Orleans version just outside Logan Square.
