I don't understand why the Gordie Howe Bridge - six lanes wide, is being constructed without a median barrier (whether adjustable or fixed) between the opposite directions of traffic. I would think given the heavy traffic and winter road conditions, that would be a priority.
Given the lower speed design it's not necessary from a safety point of view. Adding it would require either adding width to the bridge or reducing the width of the lanes/facilities on it. The former would massively add cost, the latter would be detrimental to safety. Plus would be an extra thing to maintain, and make both snow removal and revising the directional the lane balance more difficult.
Will the Ambassador bridge still be open after 2024 since it's privately owned even though for all intents and purposes the Gordie Howe is its de-facto replacement?
From a traffic stnadpoint, no as both can serve different destinations on the US side, and offers redundancy and capacity at a critical point.
The truck ferry, I believe its days are numbered as hazmat will be allowed on the GHIB but not the Ambassador.
For the Ambassador replacement span, as I've heard while replacement bridge may have the regulatory clearance to go ahead they still would need financial backing to actually do it. Obviously nothing will be made public on that until it's finalized.
Anybody think if the Ambassador gets demolished it'll be quickly imploded with explosives or be slowly torn down by being dismantled "piece by piece" like what they're currently doing with the old I-74 twin suspension bridges over the Mississippi River in the Quad Cities between IA and IL, a process that's expected to take about 18 months to complete that started last September?
Aside from the obvious joke of "fall down on its own" I could see if going either way. The critical part will be minimizing disruption the shipping for the least cost, so whether dropping the structure and towing it away immediately is the way to do it or taking it apart piece by piece with boat traffic moving underneath is up to some engineers and bean counters.
