The centers will be at 303 S. Broadway in Tarrytown and 142 Main St. in Nyack. The centers will be open from Monday through Friday from 11 a.m. to 7 p.m. and Saturday through Sunday from 11 a.m. to 4 p.m.
Officials announced the centers during a public meeting Monday night with the bridge's design-build team at the Westchester Marriott Hotel.
State officials are planning to build two parallel structures just north of the existing Tappan Zee Bridge. Each span will include four lanes of traffic and two emergency lanes. The northern span also will have a pedestrian and bike path.
Construction of the northern span will begin first, officials said. Traffic will be diverted to that span while contractors tear down the old bridge and build the southern span.
Officials stressed Monday that steps would be taken to minimize the impacts on Tarrytown, including 24-hour noise and air-quality monitoring that will be available to residents. About 90 percent of the construction equipment and materials will be transported by barge on the Hudson River, and the rest will be driven directly off of the Thruway, said Brian Conybeare, special adviser to the governor on the bridge project.
Officials announced that contractors would conduct test borings and establish staging areas in March, with the first test pilings being done in June. Dredging is scheduled to start in August, on a schedule to minimize effects on sturgeon in a plan approved by the New York State Department of Environmental Conservation.
