WATFORD CITY, N.D. — A new post office is operating in the heart of the western North Dakota oil patch.

The 9,000-square-foot building in Watford City has nearly 3,000 post office boxes, 16 sections of parcel lockers and two service windows, along with more parking space and capacity for 10 postal carrier routes.

The U.S. Postal Service announced plans for the facility two years ago to better meet the needs of the growing oil patch city. U.S. Sens. John Hoeven and Heidi Heitkamp announced Monday that the post office was open for business.

The Postal Service says its annual lease for the building is $171,000.
