Warren Bridge opens.

Also known as the Warren Avenue Bridge, it runs alongside the existing Charles River Bridge and connects Charlestown to the North End on the site of today’s Charles River Dam. Despite its proximity to the pre-existing bridge, permission to build it was granted by the Massachusetts legislature in 1827. That prompted Gov. Levi Lincoln Jr. to use the first use of a gubernatorial veto in state history, and a lawsuit decided by the Supreme Court in 1837.* It becomes a free bridge on August 30, 1858, and is demolished in 1974 to make way for construction of a dam in 1978.*
