One thing about traveling, it sure has improved my geography! Until this past week I did not know that Sault Ste.Marie had a sister city by the same name across the St.Marys River in Ontario, Canada. They each have different locks but are connected to each other with the International Friendship Bridge and a railway system which also goes across the river. On our boat ride we crossed the river on one of the U.S. locks, and on our return trip home we passed through a Canadian lock. On the United States side there are a total of four locks. Currently larger boats (which are generally 1000 feet long and carry more than 72,000 tons of freight in a single load) can only get through one of the locks. Plans are in the works for two of the smaller locks to be reconstructed to meet the same size specifications as the larger lock. Pictured below is the International Friendship Bridge, on our river cruise we passed under it. During the course of the day, whenever we glanced at the bridge, we usually noticed long lines of cars queuing to go through customs. We were informed by locals that on an average day it takes 2.5 hours to go across the bridge and through United States customs from Canada.
