The Andrew P. McArdle Memorial Bridge is a steel truss bascule bridge over the Chelsea Creek, just upstream of its confluence with the Mystic River and the Tobin Bridge. Also known as the Meridian Street Bridge, it connects Meridian Street in East Boston with Pearl Street in Chelsea, Massachusetts.

Luna is a historic tugboat normally berthed in Boston Harbor, Massachusetts. Luna was designed in 1930 by John G. Alden and built by M.M. Davis and Bethlehem Steel. She is listed on the National Register of Historic Places and is a U.S. National Historic Landmark. In 1985, the Luna was designated as a Boston Landmark by the Boston Landmarks Commission. Luna is the last surviving full-sized wooden ship-docking tug on the US Gulf and Atlantic coasts and was the world's first diesel-electric tugboat built for commercial service. These two distinctions have led to designation of Luna as a US National Historic Landmark. Today Luna is preserved in Boston Harbor, where her rehabilitation process has been underway since the tug was rescued from being broken up in 1995. Luna is the responsibility of the Luna Preservation Society and its progress is recorded in their website. Due to her wartime service with a civilian crew, Luna is also a member of the Naval Historic Vessel Association.

Chelsea Creek, shown on federal maps as the Chelsea River, is a 2.6-mile-long (4.2 km) waterway that runs along the shore of Chelsea, Massachusetts, and separates that community from the cities of Boston and Revere, as well as feeding part of the current Belle Isle Marsh Reservation that separates Boston from Revere. It is one of 10 designated port areas in Massachusetts.The creek starts as Mill Creek at a former pond at the intersection of Revere Beach Parkway (Massachusetts Route 16) and U.S. Route 1, now a shopping center. Mill Creek meanders east for 0.5 miles, then takes a sharp turn south, becoming Chelsea Creek, and widens significantly as it runs between Chelsea and the neighborhood of East Boston. In that area, the waterway is used by oil tankers to transport fuel to adjacent oil tanks. The creek then turns southwest and runs into the Mystic River shortly before it empties into Boston Harbor.All of the jet fuel used at Logan International Airport is stored along the Chelsea Creek, with 70-80 percent of the heating fuel in New England, and road salt for approximately 350 communities across the region.In May 1775, the American colonists won the first offensive victory of the American Revolution over the British, in a naval battle known as the Battle of Chelsea Creek.
