Craigie Bridge (first) opens.

Originally the Canal Bridge, it is built by a group that includes Andrew Craigie, Harrison Gray Otis, and Thomas Handasyd Perkins and spans the Charles River between today’s Lomasney Way (then Leverett Street) at Barton’s Point to Lechmere Point in East Cambridge. Caleb Snow later writes, “All these bridges are well lighted by lamps when the evenings are dark, and the lights, placed at regular distances, have a splendid and romantic appearance.” Originally a toll bridge, it made a free bridge on February 1, 1858. It is rebuilt (second) in 1874, and replaced (third), first as part of a temporary dam in October 1908 and then by the drawbridge in the center of the dam built in 1910.*
