Pile Driving Continues, Village Considers Independent Noise Monitoring

Since sheet pile driving on the new bridge across the Hudson River resumed last month—after Tappan Zee Constructors added noise-abatement measures—the work on land has been completed but continues in the water.

Those measures were put in place because the state shut the pile-driving operation down when monitors proved noise levels were above the contractual limit of 90 decibels. Residents and officials in the Nyacks had been complaining for some time.

“We remain concerned about the noise,” wrote South Nyack Mayor Bonnie Christian on the village website. ”We will continue to work with the Thruway’s environmental compliance team to better understand their compliance and mitigation methods, so we can gain confidence that TZC will stay within their contractual limits.”

South Nyack has been trying out sound-monitoring equipment for itself. The village’s consultant will make a report to the Board of Trustees Sept. 23.

Meanwhile, work continues on the Rockland work trestle that will hold construction equipment. According to the New NY Bridge website, construction will also continue in the Hudson River as crews place the foundation for the bridge. Work will include pile driving between 7 a.m. and 7 p.m., Monday through Friday and noon to 7 p.m. Saturday.
