Reconstruction along the Long Island Expressway 495

State of New York Department of Transportation.

Oyster Bay Expressway Route 135 & the Northern State Parkway.

Work consisted of expanding the existing three-lane highway to a four-lane highway which included a high occupancy vehicle lane. The separating grass median was removed, the existing adjacent storm drainage system was abandoned and removed, and a new central storm drainage was installed.

Various existing bridges had to be replaced to accommodate the roadway change. In addition, two new precast concrete bridges were built. Most of the work was performed during evening hours.

All work was completed ahead of schedule.
