The Rehabilitation of Echo Bridge in the Hemlock Gorge Reservation has been a long term concern of the Friends. A major restoration of the stone work was completed in 1992, but much work, including restoration of the Railings and the Echo Platform remain to be done. The following information regarding this unfinished project was provided to the Friends by the MWRA some years ago and gives some idea of the scope and complexity and cost of the project.
2205. Echo Bridge Rehabilitation
Purpose To address structural deterioration at Echo Bridge, which is a historic facility that carries the Sudbury Aqueduct across the Charles River. Rehabilitation work includes upgrades to the bridge facade, surface, railings, and stairways.
|Phase||Total contract Amount ($000)||Begin date||End date|
|Design||In-house||Sept. 1987||on hold|
|Construction||$345||Sept 1991||Sept. 1992|
Echo Bridge carries the Sudbury Aqueduct across the Charles River. It was constructed in the 1870's and was patterned after the old Roman aqueducts consisting of a series of arched spans. The structure is a National Historic Landmark. The aqueduct bridge was constructed of concrete masonry with stone and brick facing. The stone and brick mortar joints have deteriorated and ties which secure the brick facing to the structure are failing. The railing, steel staircase, and surface walkway of the bridge also need repair.
Due to the anticipated high cost of upgrading and repairing Echo Bridge to meet applicable specifications, the MWRA has postponed the remaining railing work while outside sources of funding are explored and the neighboring communities are consulted about safety and historic preservation issues. No additional funds for construction are included in the proposed CIP beyond those expanded for repairs completed in 1992.
