National Grid to Begin Gas Main Replacement in Jamaica Plain This Week

National Grid plans to upgrade natural gas mains along Centre Street in Jamaica Plain this week. 

The company is set to replace more than 2,100 feet of natural gas main on the south side of Centre Street from Sheridan Street to Wise Street, National Grid said in a statement Tuesday. 

Once the project is complete, the Boston Water and Sewer commission will begin an infrastructure replacement project in the same area, with work taking place from 9:30 a.m.to 3:30 p.m. daily. 

Traffic is expected to flow normally in both directions on Centre Street during the project, but National Grid is urging drivers to remain cautious of workers in the area. Parking restrictions for both sides of Centre Street will be in effect during the project. 

The company said the upgrade to the infrastructure in the area from original cast iron main to industry-standard plastic piping will help provide safe and reliable natural gas service to local customers. 

The project in Jamaica Plain is part of a larger main replacement program; the company is upgrading older mains to more modern materials and investing in its natural gas infrastructure. The company said that in 2013 alone, it replaced more than 160 miles of natural gas main in Massachusetts.
