Thousand Islands Bridge Thousand Islands Bridge The Thousand Islands International Bridge () is an international bridge system over the Saint Lawrence River connecting northern New York in the United States with southeastern Ontario in Canada. Constructed in 1937, with additions in 1959, the bridges span the Canada–US border in the middle of the Thousand Islands region. All bridges in the system carry two lanes of traffic, one in each direction, with pedestrian sidewalks. The bridge is managed by an American company. The actual international border bridge crossing is a set of two parallel long bridges between Wellesley Island in the United States and
Thousand Islands Island, which had been left unfinished for over 75 years upon the untimely death of George Boldt's wife. It has since been completed over the recent decades in accord with Boldt's original plans. The Thousand Islands have long been a center for recreational boating. Large steam yachts, many designed by Nathanael Herreshoff, required distinctive yacht houses. The region was known also for innovative power boating during this period. Three local yacht clubs hosted the Gold Cup Races of the American Power Boat Association for nine consecutive years. To be considered an island, a piece of land must stay above water
