ROXBURY, NJ – New Jersey Natural Gas (NJNG) is about to begin a major system upgrade in Roxbury, one that will double the diameter of a gas main running along more than a mile of Route 46.

The project - scheduled to begin Aug. 13 and last until the middle or end of November - will take place along the eastbound side of the road between Route 10 and Berkshire Valley Road, said NJNG Spokesperson Michael Kinney.

Both he and Roxbury Department of Public Works Director Richard Blood, noted the construction will take place mostly at night in an effort to minimize its impact on motorists. “We’ve been coordinating this with local police in the township,” Kinney said. “Work will be done primarily during night hours, Monday through Thursday … There will be lane shifts, but the road will not be closed.”

Kinney said that, “because work is being done at night, it is expected to have minimal impact on any business or homes in that area,” but he acknowledged that “as with all construction work, there will be some noise.” However, Kinney said the company expects the “impact (to residents) will be minimal.”

The company is going to install 6,700 feet of 12-inch diameter gas line to replace the existing 6-inch steel main. Kinney said the $2 million upgrade is going to “increase reliability to the Roxbury area.” He said the current gas main was installed "prior to" 1950.

“The reason you put in larger pipe: As the area continues to grow … you don’t want to be replacing these on a year-to-year basis,” he said. “It doesn’t mean it is necessarily doubling the (immediate) capacity.”

NJNG has about 5,600 customers in Roxbury, according to the spokesman.
