The Ambassador Bridge
Spanning the Detroit River between Detroit and Windsor, Ontario, the suspension bridge accounts for a whopping 25% of all trade between the two countries, with $328 million (417 million Canadian dollars) in goods crossing each day.
The bridge is critical to the food sector in both countries as well as the auto industry; with crossings all but shut down, shortages have forced plants on both sides of the border to go offline or operate at reduced capacity.
On Friday, a judge ordered protesters at the bridge to end the blockade and police warned that people blocking the streets could be subject to arrest and have their vehicles seized.
Premier Ford has declared a state of emergency that would allow penalties of up to a year in jail and fines of about $80,000 (100,00 Canadian dollars) for anyone impeding the movement of goods, people and services along critical infrastructure.
Michigan Gov. Gretchen Whitmer urged Canadian authorities to resolve the standoff quickly, saying, "It's hitting paychecks and production lines. That is unacceptable."
