North of the Patchogue Highlands area, the paved road became a dirt trail and carried the former ROW towards Holtsville Station.
The dirt trail was visible where it crossed Woodside Avenue and then disappeared entirely at the latter-day site of the town dump where it was obliterated (see below).
The Town of Brookhaven installed a landfill on part of the former ROW, leaving a portion of it as an entrance at Blue Point Road.
During a 2009 repaving project of North Ocean Avenue by the Village of Patchogue Department of Public Works, the former trolley tracks were uncovered and removed for preservation.
The line was originally owned by the South Shore Traction Company and ran primarily along Middle Road, Blue Point Avenue, and Montauk Highway.
