People who cross the Neponset River between Dorchester and Milton on Granite Avenue traverse a bridge that looks like, and is, a relic of the days when the Neponset River was a working river.

The nation's first railroad, built in 1826, ferried granite blocks from a Quincy quarry to a wharf on the banks on Gulliver's Brook, which is just upstream of the bridge, and from which the builders of the Bunker Hill Monument got their granite blocks.

A report that somebody jumped off the Neponset River Bridge around 8:15 p.m. brought Boston firefighters by land and sea until they got an update that the jumper was at the Granite Avenue drawbridge upstream a bit, where they met state troopers, who told them that it was a couple of kids jumping off the bridge - who came out soaking wet on the Dorchester side and then ran away when they spotted a statie looking at them.

Ed Coppinger, who happened to be right in the area, reports that 30 first responders showed up, before realizing it was just a couple of kids, not a potential suicide.
