 It serves the most direct route between the major cities of Seattle, Washington and Vancouver, British Columbia, and the crossing is the third-busiest on the border with up to 4,800 cars a day.Wait times can be up to four hours; traffic lights exist on the southbound lane, with timers showing when the light will turn green so drivers can turn off engines, visit the park, and use public restrooms.Between the two border stations sits the Peace Arch Park, where visitors are free to cross the border within the confines of the park.
