Tappan Zee Constructors have placed the first of four devices to monitor noise, vibrations and air quality on the Rockland County side of the Hudson River as part of the $3.9 billion bridge replacement project, state officials said on Wednesday.

The device was installed at the Salisbury Point condominiums, a stone's throw from the bridge landing in South Nyack, said Brian Conybeare, a special adviser to Gov. Andrew M. Cuomo on the new Tappan Zee.

Currently, Tappan Zee Constructors plans on installing three other monitors in Rockland County, including one on River Road in Grand View. Four monitors have already been placed on the Westchester County side of the river in Tarrytown.

Locals hope they install more devices throughout South Nyack, Mayor Bonnie Christian said.

"We didn't think they did a fair analysis of where these noise monitors should be," she said. "You have people who live on the hillside above the Thruway. You have people who live near the river near where the staging and construction. We've asked them to re-evaluate where they put them and why."

The monitors are shiny metal boxes, about the size of large toasters, fixed on poles slightly shorter than an average-size person. The devices are supposed to make sure work on the bridge, from pile driving to dredging, doesn't cause too much of a ruckus or pollute the air for bridge neighbors.

The monitors will work all day and night for the duration of the bridge project, said the bridge's website. Residents will eventually be able to observe the monitor's tracking via the website.

So far, Westchester County residents have registered two complaints about noise, Conybeare said. The complaints didn't stem from noise levels that were higher than those set by Tappan Zee Constructors' contract, he said. But if they had been, the state could have shut down work until the company addressed the noise issues.

South Nyack residents were scheduled to meet with Conybeare and others on Friday morning to discuss the issue. The state and construction company have been open to considering placing more monitors in the village, Christian said.

"I'm hopeful we can come up with something that is going to work out for the village, the state and TZ Constructors," Christian said.
