CITY OF NEWBURGH — After two years, those pipes - the 80,000-pound behemoths for New York City’s $1 billion fix of its leaking Delaware Aqueduct - are finally getting a move on.

The city’s Department of Environmental Protection and its contractor, Kiewit-Shea of Omaha, Neb., will begin moving the 230 pipes Wednesday, a roughly eight-mile journey from the storage yard at Water Street and Walsh Avenue in the City of Newburgh to the job site off Route 9W in the Town of Newburgh.

The one-inch thick steel pipes will be used to reinforce about three-quarters of the 2.5-mile bypass tunnel that Kiewit finished boring under the Hudson River last month to circumvent the leaking section of the aqueduct.

They will be lowered down a 900-foot shaft and into the tunnel, welded into place and covered with another layer of concrete.

“The public impact is going to be minimal,’’ said Newburgh City Manager Joe Donat. “It’s going to happen in the middle of the night, and it’s not going to be any different than moving a wide load on a highway.”

“I don’t foresee any problems,’’ added Newburgh Town Supervisor Gil Piaquadio. “I’ve talked to homeowners along the route, so they know what to expect.”

The pipes, 16 feet in diameter and 40 feet in length, will be transferred at a rate of two a night – but not necessarily every night – over a period of months.

Sean McAndrew, the DEP’s executive director for the project, said the pace of moving the pipes will depend on the pace of Kiewit’s installation of them since there is limited space for stockpiling them at the job site.

The route will send the trucks across Water Street, over the CSX tracks, to the Steelways Inc. yard where the pipes arrived on barges in 2017. From there, they will follow a City of Newburgh right-of-way north to Washington Street and travel back across the tracks to Water Street.

Then, it’s Water Street to Leroy Place to Old Balmville Road and out to Route 9W at the Middlehope Fire Department - all at speeds of up to 5 mph.

The DEP and Kiewit have held multiple meetings with the city and town and conducted a mock test of the route with a mock pipe fashioned from white PVC piping on a flatbed truck to pinpoint where trees had to be trimmed and utility wires raised.

Kiewit also took borings of city and town roads and posted bonds for their repair in the event of damage and paid for municipal police to escort the trucks or monitor their passage.
