Engineer’s Weekend in Sault Ste. Marie is the last Friday in June. There’s something for everyone, historic open houses, spectacular vistas and the opportunity to get a behind-the-scenes look at the great Soo Locks.
Check out these nine interesting facts about the Soo Locks to inspire your visit from Sault Ste. Marie Convention and Visitor’s Bureau.
A man-made marvel and the busiest lock system in the world, by cargo tonnage, yes the Soo Locks! On average, between seven and ten thousand ships come through the locks during the shipping season each year. Built in 1855, these locks connect Lake Superior to Lake Huron and beyond. We have repeat visitors every season; they call themselves Boat Nerds, that watch ships from all over the world use this free lock system. Now here are some facts about the locking system and the St. Marys River.
$500.4 Billion value attributed to the iron ore shipped through the Soo Locks each year. An average of 80 million tons of cargo moves through them each year.
7,000 passages each year – Crews at the Soo Locks complete these lockages during the 42- week- long navigations season. They are open 24 hours a day. Can you take your personal boat through the locks? Yes, as long as you have a motor and permission from the lockmaster.
2,342 miles- ships from all over the world visit this port as the locks are a part of the Saint Lawrence Seaway, which connects Duluth, Minnesota to the Atlantic!
22 Million gallons of water to lift a boat. The locks are powered by gravity itself! Water moves in and out of the lock chambers by just opening and closing valves.
1000 foot boats- There are 13-1000 footers on the Great Lakes, and the largest boat that comes through the Soo Locks is the Paul R. Tregurtha, in at 1013 feet 6 inches which is larger than three football fields! The first vessels on the great lakes were 40 foot-long canoes.
9 hours between Lake Superior and Lake Huron, it takes a freighter about nine hours to pass through the St. Mary’s River system
21 foot drop- A thick layer of bedrock holds back the waters of Lake Superior where it joins the St. Marys River. This drop prevented boats from passing through. This reddish sandstone lines most of Lake Superior southern shores and is about 1000 feet-thick. The Fairbanks Scale Company, which is still in business today, built the first permanent lock, State Lock.
3-4 cents per ton- From 1855 to 1881, this was the toll, but today it is free.
The propeller in Soo Locks Park is from a steamer named the Independence, which exploded just northwest of today’s locks. One crewman is said to have survived a trip down the rapids on a hay bale from the ship.
Now that you know more about the Soo Locks, come and visit us during Engineer’s Weekend, when you can go into the locks and get up close and personal with this engineering marvel! Can’t make it that one day of the year? You can visit the Soo Locks Park anytime between late March and Mid-January to see the freighters go through the locks.
Engineer’s Day is always the last Friday in June, which falls on the 30th in 2017. See what Engineer’s Weekend is all about in the video below.
