The Navy Yard in Charlestown is about to receive a substantial upgrade.
The National Park Service awarded a $4.8 million contract to replace water main, hydrants, valves and water distribution pipes within and around the park, according to a recent report in the Charlestown Patriot-Bridge.
The project would entail the removal of hazardous obstacles and asbestos from a utility tunnel running under First Avenue. In addition, abandoned gas and steam pipes, as well as other utilities older than 100 years will be removed from the tunnel. The pipes being replaces were first installed in 1902, according to the report.
The project, set to begin in March, is expected to last about 14 months; some sidewalks will be impacted during the water pipe replacement phase. The contract for the work was awarded to R. Zoppo Corporation, based in Stoughton.
