Yes. Traffic will be impacted southbound on Commack Road during work hours. Flaggers will be on site to mitigate traffic issues to the greatest extent feasible. Periodic temporary lane closures on Commack Road and the LIE N Service Road  for specific construction activities may be necessary.

The vast majority of this work will take place on the Cumberland Farms property at the intersection of Commack Road and the LIE N Service Road.

While our crews will make efforts to keep disturbance to a minimum, there will be noise associated with this project. Most of that noise will occur while excavation is underway as contractors use heavy equipment.
