Step onto the scenic pedestrian promenade overlooking the mouth of the Fort Point Channel, a historic tidal waterway that separates downtown Boston from the Seaport District and South Boston. Here stands the historic Northern Avenue Bridge, a rare three-span iron truss swing bridge constructed in 1908 by the Boston Bridge Works to accommodate heavy industrial railway and wagon freight traffic to the marine terminals.

The bridge operated using a massive central turntable mechanism powered by compressed air and electric motors, swinging its 283-foot center span horizontally to allow deep-draft masted vessels and tugboats to pass into the manufacturing basins of the inner channel.

Fort Point takes its historic name from a colonial fortification erected on a high clay promontory in 1632, armed with heavy cannons to protect the town from naval assault. In the late nineteenth century, the Boston Wharf Company extensively filled the tidal marshlands, creating the largest industrial wool-storage and shipping district in the United States. Today, the channel has been reborn as an ecological and cultural jewel: historic brick warehouses line the western banks, while modern glass headquarters of tech and biotechnology firms gleam across the water. Seasonal public art installations float directly in the waterway, including floating kinetic sculptures and lighted lanterns that glow at dusk.

Looking down the length of the channel, you admire the striking contrast between gritty nineteenth-century industrial bridges and sleek twenty-first-century architectural renewal. The calm waters reflect the changing sky, offering an intimate maritime perspective far removed from the bustling traffic of the downtown avenues. The quiet lapping of tidal waters against the stone bulkheads and the open horizon toward the harbor islands evoke the historic transition from busy shipping docks to welcoming public parks.

Stroll south along the western Harborwalk toward the famous Boston Tea Party Ships and Museum.
