New London — Eversource has announced an ongoing $3 million construction project to upgrade its gas distribution system here with the replacement of two miles of existing cast iron and steel pipes with plastic pipe.

In a statement, Eversource said the new pipe is safer, more durable and better able to handle fluctuations in underground temperatures.

The project is underway, with crews working — weather permitting — Monday through Friday between 7 a.m. and 4:30 p.m. Work will be done along Cedar Grove, Connecticut and Lincoln avenues; Broad, Center, Channing, Cleveland, Dow, Elm, Georgiana, Granite, Learned, Ledyard, South Ledyard and West streets; Cape Ann Court and Ashcraft Road.

Drivers may experience delays due to alternating one-way traffic. Customers may experience a short disruption to their natural gas service when the new line is being activated and they will be notified in advance by letter, phone or an in-person visit. This gas line improvement work is expected to be complete in early May.

“These investments allow us to further modernize the gas distribution system, minimizing repairs and any service interruptions,” Eversource President of Gas Operations Bill Akley said. “Proactively upgrading the system helps to ensure our customers in Connecticut have a better, stronger network for decades to come.”
