Construction at Mount Sinai South Nassau

Mount Sinai South Nassau is proposing to expand health care services at our main campus in Oceanside and in Long Beach, the home of Long Island’s first and only free-standing emergency department. In Wantagh, Mount Sinai South Nassau will bring first-class specialty care directly to your neighborhood in a modern and convenient setting that will include the latest in infection control measures in the COVID-19 era to ensure patient, staff and community safety.

Construction Updates

J-Wing Addition - Effective Friday, April 23, 2021

Ambulance access to Mount Sinai South Nassau’s Emergency Department bays will no longer be possible from Oceanside Road; all ambulances must enter the ED bays via the Nassau Parkway entrance.

This change is necessary to accommodate construction on the hospital’s new J-Wing, which will nearly double the capacity of the hospital’s current Emergency Department.

This traffic change affects ambulance traffic only! Walk-in patients to the Emergency Department will continue to enter Emergency Department lot from Oceanside Road.

Central Utility Plant - April 5, 2021 Through Friday April 23, 2021

As part of the ongoing Central Utility Plant (CUP) Project, the parking lot on the west side of the hospital (north of the loading docks) will be closed. Traffic flow and access to the loading docks remains unaffected. All persons previously parking in this parking lot can access the hospital from the main entrance where valet parking is available.

Oswald Court Closure - January 18, 2021 through May 17, 2021

As part of the ongoing Central Utility Plant (CUP) Project, Oswald Court will need to be closed between Washington Avenue and One Healthy Way to run underground utilities across Oswald Court. This work will start on Monday, January 18, 2021 and is estimated to be completed by the week of May 17, 2021.

This work is being done over multiple phases in order to ensure that:

  • Entrance and exit from Hospital's main drive remains unaffected.
  • At least one side of the Oswald Court sidewalk will be accessible for pedestrians.

Signage will be installed in the area to aid directing vehicular and pedestrian traffic.

Emergency Department at Long Beach

Please be advised that on Monday, November 16, 2020, ambulance traffic will be redirected to the East Bay Drive “WEST” driveway entrance, as construction will commence to replace the existing generator at the Free-Standing Emergency Department (FSED) located at 325 East Bay Drive, Long Beach, NY. The scope of work will require the east driveway to be closed for the duration of construction which is expected to conclude early March 2021. Ambulance traffic will continue to have access to the FSED via the west driveway on East Bay Drive.

Long Beach Medical Arts Pavilion

PSEG will be onsite to remove the existing poles, overhead wires, decommissioned transformers and utility equipment at the site. The PSEG work, starting this Saturday, November 31, 2020, is expected to take five days to complete.

Central Utility Plant

In January, 2020, Mount Sinai South Nassau began construction of a new, energy-efficient $90 million Central Utility Plant. The new plant will upgrade the hospital’s electrical, heating, ventilation and cooling systems and fortify the hospital’s infrastructure against potential future storms. The plant also will help provide power for a planned four-story addition with new operating suites, an expanded emergency department and 40 new critical care beds, all of which is part of a more than $400 million long-term strategic growth initiative designed to improve service for patients across the South Shore of Long Island. Hundreds of building trade jobs will be created as these projects are constructed.
