Echo Bridge is a historic masonry bridge spanning the Charles River between Needham to Newton Upper Falls, Massachusetts, and Ellis Street in Newton. The bridge carries the Sudbury Aqueduct and foot traffic, and is located in the Hemlock Gorge Reservation. At the time of its construction in 1875–1877, it was the second longest masonry arch in the country.

The bridge was listed on the National Register of Historic Places in 1980, and was named an American Water Landmark in 1981.

Description

The bridge crosses over Hemlock Gorge where the Charles River passes over the fall line in Newton Upper Falls. There are still old mill buildings in view from the bridge, but most of the gorge remains naturally overgrown with hemlocks. The bridge has two viewing locations, the pedestrian walk on top of the bridge and a platform underneath where visitors can hear the eponymous echoes. Views include white water, a waterfall and the hemlock-lined gorge. The 23-acre (93,000 m²) Hemlock Gorge Reservation including the gorge is maintained by the Massachusetts Department of Conservation and Recreation. The bridge is located just off Route 9 where it crosses Route 128. Despite being in the midst of a tangle of highways, the river itself is tree-lined and natural.

The bridge is 500 feet (150 m) long, and consists of a series of seven arches. The longest of these, that crosses the Charles, has a span of 137 feet (42 m), and is a segmented arch with a radius of 69 feet (21 m) and a crown of 51 feet (16 m). Five of the arches span 37 feet (11 m), while that spanning Ellis Street is 28 feet (8.5 m). At its crown the bridge is approximately 70 feet (21 m) above the river. The bridge's foundations are made of granite resting on bedrock.^[2]

The bridge was closed to the public for much of 2006 to permit repairs of the railings, which were decaying and which do not meet modern safety codes.^[3] Because of the cost of rebuilding the historic railings, chain link fencing was installed on each side, allowing the bridge to be reopened. This fencing was later replaced by a set of modern railings inside the historic railings. Efforts are underway to secure funding to reconstruct the historic railings.^[4]

The aqueduct, which has been serving only as an emergency backup for some years, was reactivated during a state of emergency declared on May 1, 2010. The line was used to carry clean water to parts of 38 communities affected by a catastrophic failure elsewhere in the MWRA system.
