Binghamton, NY (WBNG Binghamton) The New York State Department of Transportation is entering another big phase of its Prospect Mountain project.
DOT crews set the first steel girder, a support beam for the new bridges crossing the Chenango River.
Each girder ranges from 60 to 125 feet long and weighs up to 60,000 pounds.
Drivers traveling while crews are setting one of 50 steel girders may notice a slow commute.
"We're working with NY State Police. They are slowing traffic down. We did that last year where we were able to do a rolling slow down," said DOT Public Information Officer Dave Hamburg.
But after the bridge steel is set for the new bridges, there's more work to be done.
"The next thing that comes would be the bridge steel. After the bridge steel then we'll take care of pouring the deck concrete. Eventually we'll have brand new bridges that will be here. And be able to remove the old bridges," Hamburg said.
That phase of the project is expected to be completed by the spring of 2014.
The bridges will meet updated design specifications and allow wider lanes and shoulders to be added.
"We're approximately 25 percent complete. We're looking at this phase one of the project being completed by the end of 2015, then being able to move to phase two of the project," Hamburg said.
Phase two of the project will start at the end of 2015 and run through 2018.
