Peace Arch State Park, Washington

The Peace Arch is a monument situated near the westernmost point of the Canada–United States border in the contiguous United States, between the communities of Blaine, Washington and Surrey, British Columbia. Construction of the 20.5-meter (67 ft) tall arch was headed by American lawyer Sam Hill and dedicated in September 1921. The Peace Arch commemorates the signing of the Treaty of Ghent in 1814, and symbolizes a long history of peace between the two nations. The monument is built on the exact U.S.–Canada boundary, where Interstate 5 on the U.S. side of the border becomes Highway 99 on the Canadian side, in the grass median between the northbound and southbound lanes.
