If you happen to notice a suspicious looking piece of equipment attached to the underside of the Elliot Street bridge over the Charles River – don’t worry. The city’s engineering department is measuring the bridge’s shake, rattle and roll with a small seismograph. There’s been some degradation in the stone arch that supports the bridge and the city’s trying to get a handle on what’s going on.
The original bridge was built in the 1700’s (Cook’s Bridge), and here’s a bit of its history. (be sure to also check out the “Baby Ghost at Upper Falls” story just below it)
