A bridge rehabilitation project in the Town of Brookhaven will impact traffic on the Long Island Expressway in coming weeks, but officials said the good news for drivers is that the work is scheduled overnight.

The state Department of Transportation said construction-related closures will take place on the eastbound and westbound LIE in the vicinity of Exit 61, Patchogue-Holbrook Road, and said the roadwork is scheduled to take place between 10 p.m. and 5 a.m.

Eastbound closures will take place Sunday through Thursday, while westbound closures will take place Monday through Friday. Those nightly closures, which began Monday, are expected to last about two weeks with intermittent closures to follow thereafter — until the rehab is complete.

The $9.6-million project is being undertaken “to preserve the structural integrity of the bridge” and to “maintain the safety of motorists and pedestrians.” The renovations include building a new structural bridge deck, new roadway approaches, wider shoulder lanes, new sidewalk, improved traffic signals and new landscaping. The project is scheduled to be completed by the end of the calendar year, officials said this week.

As a result of the scheduled closing, officials are encouraging drivers to use alternate routes — or to allow extra time for anticipated delays. During the closure periods, mainline traffic on the LIE will be detoured on to the service roads.

Traffic on the bridge itself also will be affected, officials said. Traffic on the service roads will be affected by lane closures, as well — lanes being closed between 10 a.m. and 3 p.m. A pedestrian shuttle will replace pedestrian access to the bridge and is available 6 a.m. to 6 p.m., officials said. Officials said that “on-demand” shuttle service can be accessed via phone at the taxi shelter at the construction site.

Officials advise that the work is weather-dependent, meaning schedules can be affected by adverse weather conditions.
