PSEG Long Island: Riverhead and Canal Substations

The following construction schedule for the Riverhead to Canal Second 138kV Underground Cable Project is provided by Taihan USA, the prime contractor working on behalf of PSEG Long Island.

The following is the construction update for the Riverhead to Canal Second 138kV Underground Cable Project for the Town of Southampton for Monday, November 23, 2020 and Monday, November 30, 2020.

Location of Work: Sunrise Highway, Old Riverhead Road, the Canal Road eastbound onramp, and Suffolk County Route 51.

Description of Work: Access way development; cable pulling preparation; splice manhole and conduit installation.

Timeframe of Work: Daytime work hours (7 a.m. to 7 p.m.)

Details of Work: On Monday, November 23, 2020, crews will continue to develop the temporary access way in the grassy area south of the Sunrise Highway travel lanes in order to provide access to the new splice manhole locations between Quogue Riverhead Road and Riverhead-Hampton Bays Road (Route 24). Crews will be clearing vegetation, removing soils, and adding base materials for the access way. The work is planned for daytime hours (7 a.m. to 7 p.m.), and no traffic impediments are anticipated. On Monday, November 23, 2020, crews will be east of the Riverhead-Hampton Bays Route 24 interchange on Sunrise Highway, developing access and egress points at the Old Riverhead Road near Squiretown Road. The access ways will be developed for safe construction access, and include clearing of vegetation and paving. The work is planned for daytime hours (7 a.m. to 7 p.m.). No traffic impediments are anticipated with this work. On Monday, November 23, 2020, crews will begin developing a similar access way at the Sunrise Highway bridge over Newtown Road near Newtown Court. Crews will remove vegetation, and begin grading the access way. On Monday, November 23, 2020, the Canal Road eastbound onramp to Sunrise Highway in Hampton Bays remains closed. NOTE: Due to concrete panel work, the eastbound onramp will be closed to traffic until approximately Wednesday, November 25 at noon. Please seek alternative travel paths. Additional information to be listed on this website. Beginning on Monday, November 30, 2020, crews will be placing Splice Manhole 38.5 in the Canal Road near the Shinnecock Canal Bridge. For the week of November 30, 2020, Canal Road will be closed with detours to allow for the work. Crews will excavate the roadway, lift and place the new splice manhole, and restore the roadway. Finally, cable pulling and splicing will also occur during the weeks of November 23, 2020 and November 30, 2020. Cable pulling consists of using large spools to feed the new electric transmission cables through the splice manholes and into the newly-installed and existing underground electric conduits. This work will primarily be along Sunrise Highway, and will not impede traffic, with the exception of Monday, November 30, 2020, when crews will be pulling cable from Splice Manhole 4.5 to 3.5, which is along Suffolk County Route 51 north of Speonk-Riverhead Road. The work is planned for daytime hours (7 a.m. to 7 p.m.). Note: Crews will be working in the LIPA-owned right-of-way pulling cable during this timeframe as well. Cable splicing consists of workers, using a climate-controlled work trailer, working within it and below ground within the splice manholes, completing the splicing of the new electric transmission cables. The work is continuous, and lasts approximately six days.

Travel impacts: Work will be off of Sunrise Highway in the grassy area to the south of the travel lanes. Travelers should be mindful of construction activities. Single lane closures on Suffolk County Route 51 should be expected during cable pulling and splicing activities. Detours for the Canal Road work are posted on this website.
