The Burleigh County Commission on Monday voted to end a fledgling partnership with Friends of the Rail Bridge after learning it could not help provide the nonprofit with additional insurance, leaving the future of the historic Bismarck-Mandan Rail Bridge unclear. State's Attorney Julie Lawyer informed the commissioners that a memo from Friends of the Rail Bridge said information provided by the group at the March 15 commission meeting was "misleading or in error." Friends of the Rail Bridge wants to stop BNSF Railway from demolishing the 138-year-old bridge spanning the Missouri River to make way for a new structure. The preservation group and railroad signed an agreement with the U.S. Coast Guard in January outlining paths to either keeping or removing the bridge. The Coast Guard decides on projects proposed along that part of the Missouri River to âensure the structure does not unreasonably affect navigation,â according to a Federal Register notice.
