Arsenal Street Bridge

Arsenal Street Bridge is a road bridge spanning the Charles River, connecting Arsenal Street in Watertown to Western Avenue in Allston, Boston. The structure carries traffic between the two riverbanks and forms an important crossing in the urban landscape.

The current structure was built in 1925, replacing an earlier crossing from 1824. This reconstruction reflected growing traffic needs as the urban area expanded.

The bridge takes its name from the Watertown Arsenal, a former military installation that shaped the area's development and left its mark on local geography.

The bridge is designed for vehicular traffic and typically requires navigation from the Arsenal Street side to the Western Avenue side. Visitors should be aware of regular maintenance that may affect normal use.

Located at coordinates 42.3617°N and 71.1472°W, the bridge functions as part of a larger network connecting Watertown, Boston, and Cambridge.
