Project Overview

Tree Work at Admiral Street/Route 146

To prepare for underground conduit work that will pass below Route 146 (no traffic impact), National Grid is removing a selection of trees from the area in coordination with RIDOT. As part of the restoration process, trees will be replanted according to RIDOT permit requirements. See the project map for more details.

Phase II Construction In Progress

Phase II construction activity is now in progress and will conclude in the fall 2021. The work will take place at various work zones along South Main Street, North Main Street, Charles Street and Admiral Street. National Grid will also be restoring areas impacted by 2020 construction beginning in the spring of 2021. The restoration process includes replacing sidewalks, replanting trees and repaving the project route. National Grid will continue to coordinate work with impacted abutters for the duration of the project. All work zones will be clearly marked and protected, and a traffic management plan will be in place. Project progress can be followed on our interactive map.

Phase I Construction Complete

National Grid has concluded construction on Phase I of Power4Tomorrow with plans to resume construction on Phase II in spring 2021. There will be some light activity taking place during the winter months to prepare for Phase II, but it will not include excavation or any long-term work zone setups. All work zones will be clearly marked and protected, and a traffic management plan will be in place.

As the name implies, National Grid’s Power4Tomorrow: Downtown Reliability Project is an investment in the city’s electrical transmission infrastructure aimed at reinforcing the safe and reliable delivery of power throughout the Downtown Providence area, and beyond, for years to come.

Located entirely within existing rights-of-way – including travel lanes and sidewalks – along South Main Street, North Main Street, Charles Street and Admiral Street, components of Power4Tomorrow include:

  • Replacement of approximately two miles of existing 115kV transmission lines (installed in 1939 and 1946) located between the corner of Clarkson Street and Admiral Street Cable Terminal and Dollar Street in Providence
  • Replacement of a majority of the existing manhole locations with duct bank (underground conduit), resulting in the elimination of approximately 44 manholes
  • Re-use of approximately 60% of existing duct bank to install modern underground cables
  • Significant equipment upgrades inside Admiral St. Cable terminal to support this project

Construction began in spring 2020 and is expected to be complete in early 2022. National Grid has worked closely with city and state officials to develop traffic management plans, and will coordinate with other entities (e.g. RIPTA) whose services will be directly impacted by this construction.
