Sure, thats what they say. But by building it for vehicles, all it takes to allow all cars to use it is changing a sign.
The design shown is clearly not compatible with letting normal drivers on it for safety reasons as much as anything else.

The road intersection on the Atlantic side means it wouldn't accomplish much of anything with private traffic utilizing it.

It would be many times cheaper if it was designed only for peds, because you wouldnt need to support the weight of heavy vehicles.
If it was just a basic, narrower, bike/ped bridge to make a connection without any of the fanfare, sure. The huge thing being shown? Probably not so much.

A dense crowd of people weighs as much or more per sq ft than vehicles typically do. Your typical pedestrian bridge doesn't need massive supports and girders because it's narrow (in relative terms) and can't physically hold that many people for a unit of length.

But this thing as proposed has lots of space and is theoretical social space that you can very much expect will someday have a crowd of people shoulder to shoulder, whether that's for fireworks or an arts event, or whatever.

It'll have to be built to hold probably as much or more total weight than if it was a vehicle bridge. It'll certainly get far less wear and tear and need less maintenance/repairs by not seeing vehicle traffic, but I'm not sure that you save much on construction.

I know they chose a design, which doesnt appear to be going anywhere lately, but I came across an interesting proposal and website that I had never seen before. Looks really good, much better than the other half assed proposal. This would truly be an icon on the other side of the skyline. It would also add a pinnacle and some flair to an otherwise buzz cut end of the skyline. Id love to see this built instead.

Am I the only one who finds that design weirdly too-tall? It looks like someone made a hybrid of the Zakim Bridge and the Golden Gate Bridge, which isn't a bad thing, but why is it so tall?

We should have stuck to our new england roots

Honestly, that crossing is going to be windy and cold AF for a good part of the year. A modernized covered bridge with amenities wouldn’t be a bad idea. Movable glass walls — open for nice days closed for winter. Make it taller and with steel instead of wood. Put a bar in the middle with a dock below. People seem to put limits on what a bridge can be.

Is this project delayed indefinitely?
it seems that limbo is where a lot of erstwhile transportation projects in Massachusetts end up. There's an initial rolling out of the preliminary deign(s), but then nothing for years....for decades....for ever.

I've heard that this was definitely more of a priority under Walsh, when it got a lot of criticism given the cost relative to other citywide priorities (and Mayor Wu is definitely thinking citywide with other transportation projects and programs).

It looks extremely expensive. I get wanting to make it nice, but theres so much extra/unnecessary stuff added on to that proposal that just blows up the cost. The platform that drops down to the water is cool, but is it really necessary with different harborwalk infrastructure all over the place nearby? Then they also added those beams that are only decorative to envoke the old bridge and create a visual of an “iconic”/gateway structure at the mouth of the channel. Again cool, but a lot of extra money for something with 0 structural value that I can see.

Thats okay, but for way cheaper they could just float in a prebuilt tied arch bridge and lift it in to place. It would be quick and easy to do plus have an “iconic” arch that is actually structural, and it could be lit up at night and would look great there. It could be a pretty small bridge too saving more money if they just make it wide enough for 2 dedicated center running bus lanes with bike/ped paths on either side. This would be cheap, functional, iconic, and easy to do. They need to go back to the drawing board and try again, theres options out there that can save costs and still be just as if not more iconic than this proposal in this spot.

Obviously something like this spanning the entire channel would be the most iconic, but also most expensive and not necessary here.


Instead they can use something small like this that just spans the center of the channel from the middle 2 piers.
