Lane closures on the New York State Thruway

On several overnights during the week of Oct. 27, motorists using the northbound New York State Thruway (I-87/I-287) will encounter two- and three-lane closures. With closure times varying during each overnight, please consult the chart below for specific details. The closures are necessary to facilitate paving operations in the vicinity of exit 9 and the Westchester toll plaza.

All lane closures are subject to change due to traffic, weather or emergency situations. Please visit http://www.thruway.ny.gov/travelers/map/index.html?layer=incidents for real time information regarding traffic conditions.

Pile Driving and Other Construction Activity
Construction will continue in the Hudson River as crews place the foundations of the new bridge. Work will include pile driving between 7 a.m. and 7 p.m., Monday through Friday and noon to 7 p.m., Saturday.

A second shift of workers also will continue pile welding, pile cleanout and concrete placement operations associated with foundations.

In addition, work is continuing on the new bridge’s landings. In Westchester, work includes drilling holes into the bedrock for the foundation of the landing. In Rockland, a similar operation is improving the strength of the soil by using aggregate piers, which are constructed with a drill that mixes soil and aggregate (i.e., crushed stone) to form a strong base for the new bridge’s abutment and foundation. The drilling process is less audible than impact pile driving and noise-reducing measures are being implemented to further minimize sound levels. The eight-week operation is anticipated to conclude in November.

Additional work includes:

• Pile cap foundation construction
• Main span foundation construction
• River Road utility work
• Rockland trestle construction, including pile driving
• Support for river-based work from the Rockland trestle
• Survey inspections on existing bridge
