smokeybandit Posted April 1 #626 Share Posted April 1 The Howe Bridge is a new bridge though, not replacing an already critical one that was gone in the snap of a finger. Link to comment Share on other sites More sharing options...

Wikipedia confirms the span length, but also reports that the clearance is only 138 feet. So if that lower clearance (Key bridge was 185) is inherent to the design, it may not be the best choice. Theron Clearance would not be a problem. It is just a function of setting the clearance you want at the main channel and transitioning to the approach elevations. If you want to see a cable-stayed bridge with lots of clearance, look up Millau Viaduct in Southern France. Just over 1100 feet under clear on that one. 1 Link to comment Share on other sites More sharing options...

I follow a guy on Instagram who frequently posts photos of the work. Below are some of of his latest shots. I left his info on the screen shots if anyone wants to follow his account. Unlike Baltimore this bridge isn’t being constructed in a “hurried” fashion. Thanks for those links, Andrew. They are a little behind their original schedule. It was to open this year, but not till 2025 now. Link to comment Share on other sites More sharing options...

And to be fair, this one crosses a valley that drops out in the middle, not water, which is flat all the way, so several hundred feet of that clearance is kind of "free," or at least cheaper than rising that high over water.

Add to that the purchase the land on each side of the bridge, zoning etc... Who knows what type of permits they need for a structure that is built in 2 different countries and how long that would have taken. It is rather interesting thinking about it, as a person not associated with this type of job. 2 Link to comment Share on other sites More sharing options...

Rare exm Posted April 3 #639 Share Posted April 3 The problem with the clearance of the Francis Scott Key bridge, is that the Chesapeake Bay Bridge is (also) limited to 185ft so I'm not sure if they will be raising the collapsed bridge. Link to comment Share on other sites More sharing options...

Since they have to replace the Key bridge they could build it higher with the future in mind. As for the Chesapeake Bay bridge the replacing it has been approved. There are 14 options on the table. Since projects to rebuild both bridges are now on the table future proofing both bridges should be done. If Bayonne has done 215 feet wouldn’t Baltimore want to match that to compete?

If they are approaching it responsibly, they will be looking at the needs in the future. Since bridges are being built for 100+ years life span, they need to look to the future. Increasing clearances on CBB may need to be addressed at some point. Ships will continue to increase in size. Just look at the changes in the past 100 years that resulted in new locks in the Panama Canal to accommodate larger ships. 2 Link to comment Share on other sites More sharing options...

They've since decided the new span will be built next to the existing ones (which is really dumb, but, it's Maryland so no surprise).

If it needs to go from A to B, why wouldn’t they build the new one beside the old one which already has infrastructure on land. That’s what Florida did in the 80s.

Other proposals had a completely different location providing an alternate route. But it got NIMBY'd. 1 Link to comment Share on other sites More sharing options...

Yep we were hoping for a location that didn't go thru Kent Island.. So then we'd have multiple options for crossing the bay. 1 Link to comment Share on other sites More sharing options...

Is the Chesapeake Bay Bridge really a limitation on what serves Baltimore? The two channels over the tunnels should be able to accommodate larger cruise ships.... charts show 45 ft drafts on the south tunnel, and 50 ft on the middle tunnel. Duh. Disregard.... I forgot about the bridge at Annapolis with almost the same name as the CBBT..... Edited April 3 by Lane Hog 1 Link to comment Share on other sites More sharing options...
