National Grid Will Replace Sag Harbor Main Street Gas Main This Winter

A common refrain heard when there is any sort of construction work being done on the road in the summertime is: “Why couldn’t they wait until the offseason?”

Well, National Grid, which plans to replace an aging gas main on Sag Harbor’s Main Street — in the heart of the business district — is doing just that.

The utility announced last week that it will begin the project, which will run from Spring Street to Bay Street, in January, with an eye toward finishing it by the end of May.

The company will run a public service announcement in upcoming issues of The Sag Harbor Express to alert the public about the project, which it says is being designed to “minimize disturbance.”

Crews will generally work from 7 a.m. to 4 p.m., Monday through Friday, and fill in trenches as they go to reduce the impact on businesses. While Main Street will remain open throughout the project, motorists can expect lane shifts, merges and traffic delays.

Stores will remain open and sidewalks and driveways will remain accessible during the project, according to the utility. Interruptions to gas service will be scheduled and kept as brief as possible, officials added.

“This work is part of our commitment to modernizing the natural gas system, making it safer, more resilient, and better for the environment,” the company said in a release. “The new distribution pipelines also will improve reliability and support growing demand for years to come.”

Ellen Dioguardi, the president of the Sag Harbor Chamber of Commerce, said National Grid’s representatives had assured her that no more than 20 parking spaces would be out of service on any one day.

“Losing any parking spots right on Main Street is challenging, but losing them in January or February is better than May or June,” she said. “The chamber will be keeping its membership up to date on the progress of the work. I’ve asked to be kept informed of any delays or issues — and will pass that information along.”

Wendy Frigeria, a National Grid spokeswoman, said the company is mindful that winter can pose special problems for construction projects. She said the company plans to temporarily repave the road with asphalt as crews make their way down the street and will return to resurface it permanently at the end of the project.
