A stargate at the north end of Eau Claire Station and a gate at the south end of 9 Avenue Station? The perfect bridge.

But then we run the risk of catastrophe 🤔🤔🤔

That actually gave me an idea lol. Could run the train underneath the Centre St. Bridge where the 2 traffic lanes exist. It'd require strengthening and a relocation of the Eau Claire station to somewhere like 3rd Ave 1st SW, but it's doable.

Using the Centre Street bridge was one of the options looked at in the past, but in 2016 when money was no concern, they went with the deep tunnel. In 2019 when it became impossible to even reach Shepard with $5B, they had to resort to the second worst option (only ahead of elevated through downtown) probably because it was the only they could (potentially) afford. And yeah, the station would likely have been at 3rd Ave.

Looking at that makes me nauseous. 😰

It may be ugly, but it still scored higher than the current option of the new bridge. Centre Street got two checks for Fiscal Capacity and Sustainable Development, while the new bridge (plus running at grade south of 16th Ave) option only got one for Fiscal Capacity. Both got strikes for Community Well-being, Transportation, Urban and Neighborhood Development, Feasibility+Deliverability and Stakeholders.
 
If I remember correctly the problem with putting the line on the Centre Street Bridge was that it would take up two and a half of the four lanes and would as a result require the bridge to be widened

Isn't the at grade on Centre option doing the same thing with Center Street to the north? If so, why would the bridge need to be widened, if those lanes are being removed already on Center Street long before the bridge?

I think Centre Street N is wider than the bridge is today. If not it can easily be widened no?
 
Centre street north is the same width as Centre Street bridge, at least up to 40th ave area. I can be widened easier than the bridge of course, but doesn't have a lot of extra space until you get past 20th ave.

Run the train under the bridge

That doesn't make any sense. The point of using a bridge is to reduce cost by reducing the amount of tunneling. Running the train under the bridge means that the train would need a lengthy tunnel under Crescent Heights, since it would be 35m below Centre St. It would also make the 9th Ave stop impractical, would introduce a level train crossing on Memorial, and would mean that the tracks are in the 100 year flood plain (since the lower deck flooded in 2013); you'd also probably need to demolish at minimum the Chinatown Seniors Centre to make the turn onto the bridge. But none of this matters, since the clearance is only 8.7 feet and a low-floor LRV is closer to 13 feet above the rail.

You're not understanding what he's saying. Everybody knows there's a lower deck on the Centre Street Bridge, it isn't a secret.

Every issue BBB introduced is correct and completely negates any potential for use of the lower deck.
