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.
Schedule Notes: • Construction preparation: o On Monday, March 1, 2021, and continuing through the week of Monday, March 8, 2021, crews will be backfilling the areas around the splice manholes from Splice Manhole 19.5 to 30.5, which are in the grassy area to the south of the travel lanes of the Sunrise Highway from the Old Riverhead Road interchange to the Riverhead-Hampton Bays Road. The work is planned for daytime hours (7 a.m. to 7 p.m.). No traffic impacts are anticipated with these activities. • Shinnecock Canal Bridge Riser Installation: o On Tuesday, March 2, 2021, crews will mobilize beneath the eastern side of the Shinnecock Canal Bridge on Canal Road in Hampton Bays to begin the process of installing the new concrete foundations for the vertical cable tray riser structures. The structures will allow the new electric underground transmission cables to transition to the existing conduits already attached to the underside of the bridge. Crews will use drilling equipment to create a pile base for the concrete foundations. These activities will continue through the week of March 8, 2021. Beginning Tuesday, March 9, 2021, crews will then marshal on the west side of the Shinnecock Canal Bridge in the area of Canal Road West/Gate Street in Hampton Bays, and repeat the above procedures. The work is planned for daytime hours. NOTE: During these activities, Canal Road, Canal Road West, and Gate Street will be closed to traffic, and detours in place. Please take notice of signs directing traffic away from the work areas. Access to the Shinnecock Canal lock operations will continue. The work is planned for daytime hours (7 a.m. to 7 p.m.). Full road closures of Canal Road on the eastern side of the Shinnecock Canal and Canal Road West on the western side will be in place during these activities. Motorists are advised to follow the appropriate detour routes. Emergency services providers, please take notice. • Splice Manhole Installation: o All splice manholes for this project have been installed, and this portion of the work complete. • Cable pulling: o Generally, cable pulling consists of two efforts. First, the cleaning of the new conduits to remove any potential debris resulting in the civil construction process, as well as preparing for the pulling of the cables. Second, the actual cable pulling, which consists of the use of large spools to allow the new electric cables to be pulled through the splice manholes and into the existing and new conduits to the next splice manhole. Large equipment will be staged at both ends of the process to assist with pulling. The work is planned for daytime hours. Monday, March 1, 2021: Swab and clean from 36.5, located in the grassy area south of the Sunrise Highway travel lanes in the area of Newtown Court in Hampton Bays, to 37.5, located at the intersection of Canal Road West and Gate Street in Hampton Bays. NOTE: Gate Street/Canal Road West will be closed to traffic during these operations. Detours are in place. Tuesday, March 2, 2021: Pull cable from 36.5 to 37.5. The work is planned for daytime hours (7 a.m. to 7 p.m.). Work is staged off Sunrise Highway to avoid traffic impacts. Canal Road West/Gate Street will be closed during cable pulling activities. • Cable Splicing: o Generally, cable splicing includes a crew working inside of a climate-controlled work trailer positioned directly over the splice manhole to allow for access, and limitations on dust and debris being a part of the process. Crews work continuously for approximately six days to complete each splice. The work is non-obtrusive, and limited to the work trailer. NOTE: Splice Manholes 12.5 to 36.5 are located in the grassy area along the south side of Sunrise Highway and should not pose any traffic impacts to the public unless otherwise noted below. The schedule for cable splicing is as follows: Monday, March 1, 2021: Splice Manholes 23.5 and 31.5. Friday, March 5, 2021: Splice Manhole 33.5. Monday, March 8, 2021: Splice Manhole 36.5. Friday, March 12, 2021: Splice Manhole 32.5. The work is continuous for approximately six days. All locations should not see traffic impacts. • Work is dependent on the weather. • For questions or concerns, advise to call the hotline (631-315-3132), email (email@example.com) or website (www.riverhead2canal.com).
