The Jersey barriers were probably 30 feet long, and they're just formed concrete barriers that you would see on any 400-series highway from time to time if they're doing construction. It really just created a pipeline from the provincial highway to the foot of the Ambassador Bridge. There was no cross-traffic allowed, so it entirely blocked the city. For folks who were bisected because of that road, the Jersey barriers really caused the bisection to be more amplified because there was no way around them and there was no way through.
