Fortunately within Port Colborne there are sporadic signs directing through traffic through the discontinuity.

Road info: Highway 3 is generally in fairly good condition. The western segment of the route is in excellent condition but is quite congested. The central and longest segment has the most variance in condition but is in for the most part, good or fair shape. The eastern segment is once again all in good condition. The downloaded portion between Leamington and St. Thomas is at times fairly rough, but is for the most part quite lightly traveled. Highway 3 has a rural posted speed limit of 80km/h.
