Maritimes & Northeast Pipeline Map

The Maritimes & Northeast Pipeline brings offshore, onshore and LNG-sourced natural gas from Atlantic Canada to North American markets.

Maritimes extends from Nova Scotia into New Brunswick, Maine, New Hampshire, and Massachusetts where it connects with Algonquin Gas Transmission's HubLine near Beverly, Massachusetts. There it provides a seamless link for Spectra Energy systems from offshore Nova Scotia to south Texas and the Gulf Coast. The Maritimes pipeline also connects to the North American pipeline grid at Westbrook, Maine and Dracut, Massachusetts.

Maritimes delivers critical supplies of natural gas to the northeast U.S. through a reliable and economical transportation system that increases downstream market alternatives for current and future shippers.
