Description

Waterfalls abutting Echo Bridge

The bridge crosses over Hemlock Gorge where the Charles River passes over 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 (a major interchange of the Massachusetts Turnpike is also nearby), 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]

Echo Bridge underwent extensive renovations in 2006 and was closed to the public for much of the year; it has been reopened.

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.
