Vanceboro, Maine: A Remote Border Town on the St. Croix River

Far out on Maine's eastern edge, where the St. Croix River marks the line between the United States and Canada, sits the tiny town of Vanceboro. It is about as off-the-beaten-path as Maine gets — a quiet railway and border community surrounded by lakes and North Woods. Yet this small town holds an outsized place in history, and for anglers, paddlers, and history buffs it rewards the long drive to reach it.

Where Is Vanceboro?

Vanceboro lies in Washington County, in far eastern (“Downeast”) Maine, on the west bank of the St. Croix River. Directly across the river is the community of St. Croix and nearby McAdam, in the Canadian province of New Brunswick. An international bridge and border crossing connect the two countries here, and the town has long been a railway junction linking Maine and Canada. It is a small, remote place — more wilderness than town — and that isolation is a big part of its character.

The 1915 Vanceboro Bridge Bombing

Vanceboro's claim to fame is a remarkable chapter of World War I history. In the early hours of February 2, 1915 — before the United States had entered the war — a German army lieutenant named Werner Horn placed some 60 pounds of dynamite on the international railway bridge over the St. Croix, which was jointly operated by the Maine Central Railroad and the Canadian Pacific Railway. The plot had been arranged by the German spymaster Franz von Papen.

The bomb detonated at about 1:10 a.m., blowing out windows across Vanceboro and St. Croix on a bitterly cold night, but it failed to bring down the bridge. Horn was soon detained at the local hotel by the Washington County sheriff and Canadian officers from McAdam. He was tried in Fredericton, convicted, and eventually deported. Today the episode stands as one of the most audacious acts of German sabotage on North American soil during the Great War.

The St. Croix River and Spednic Lake

Beyond its history, Vanceboro is a gateway to some of Maine's wildest water. The St. Croix River and nearby Spednic Lake are renowned among anglers for outstanding smallmouth bass fishing, and among canoeists and kayakers for remote, scenic paddling through largely undeveloped shoreline. This is border-country wilderness — forests, loons, and clean water — and a favorite of those who want a true North Woods experience away from the crowds.

Crossing the Border at Vanceboro

The Vanceboro–St. Croix crossing is a small, quiet port of entry between Maine and New Brunswick. As with any international crossing, travelers need proper documents such as a valid passport, and hours and requirements can change, so it is wise to check current border information before you go.
