re: BR Advocate Letter to Editor Solves I-10 Loop Problem

I’ve always thought the solution was simple. Build a toll road from Gross Tete to the sunshine bridge. That would take care of I10 traffic. I12 traffic will remain, but there’s no other way to fix that traffic.
That wouldn’t help the plant workers on the west side, or the traffic going east west.
The truth is another avenue for traffic to bypass BR and the I 10 mess is needed.
A bridge is only part of the solution. A means of getting people on and off the new bridge and to the current highway infrastructure and not two lane roads will be a must.

Wouldn’t the tunnel still affect the swamp and is there a tunnel in a waterway with the volume of water and sediment load of miss river?

Upgrade the old bridge and airline hwy. Truck bypass route. You're welcome

Why not a second story interstate with no exits until out of EBRP?
It's been discussed before. I'll have to find an article to link.
Austin Did this with i-35 but there are some critics of this type of proposal.
It was also discussed doing something similar along/atop Airline Highway to 12 and then connecting to i-10.
I remember all of these ideas being floated and discussed in the Advocate about 15-18 years ago.

And they’ll still be being discussed 15-18 years from now!

Feasible, but more expensive and probably longer to build than a bridge.
If it can be done in Mobile, Chesapeake Bay, the England/France chunnel, it can certainly be done from an engineering standpoint.

An elevated expressway over Florida blvd much like the westbank expressway always sounded like a good idea to me.

because the soil underneath is soft like pudding and it'd have to be deep af

Will it leak?
All tunnels leak. I believe the Belle Chasse Tunnel was call the 'Car Wash' for a reason.

I believe the river is 50' deep at Baton Rouge.
A 20' tall tunnel would only have 30 feet of water over it. Disaster waiting to happen.

The Mobile tunnels, primarily the George Wallace Tunnel (part of I-10) and the older Bankhead Tunnel, are submerged under the Mobile River, with the tunnel tops sitting about 40 to 49 feet below the water's surface, connecting downtown Mobile to Blakeley Island and the Eastern Shore

How bout the Chunnel? That had to be a bigger engineering acomplishment.

The old bridge plus Airline Hwy. was the first BR bypass. It was constructed in 1940 and extended from the bridge to the Nesser overpass.

Put the tunnel on top of the bed of the river and the river would scour out underneath it and it would collapse.
Take a look where the Amazon river meets the Atlantic. That's more comparable to the Mississippi.
Masses of water are one thing, Masses of variable volume and not predictable as to when and how long...are another set of variables.

Places like New York and even BHAM are solid rock aren't they? Sure stable and will become the foundation of the tunnel. My guess is that millions of years of river sediment and clay are what's below the Mississippi. Probably terrible material to try to build a tunnel through.
Yep,
Those TBMs would be chewing through the alluvial soil in record time with water leaking through. It is not like the Chunnel where you had a layer of dense chalk that was nearly consistent between Great Britain and the mainland that made using TBM possible and you did not have to trench. Trenching might be the only way to build a tunnel in the Mississippi. The tunnels in Chesapeake Bay and Mobile were built this way.

Interesting. I wonder what the cost difference would be.

A gillion dollars.

A tunnel under it would have to go through the mud and dirt under the river not in the water. It would need to be reinforced. May be worth too cost prohibitive but makes sense. Would be easier if we had bedrock there.

You can’t tunnel you dredge and then underwater pile drive the submerge the tunnel in sections.
Posted on 1/19/26 at 6:35 pm to titmouse
Let’s say they put a tunnel in the same spot as the bridge, wouldn’t that land be cleared regardless? How many trees are really being saved either way? And also, how comfortable would you feel driving through a dark, confined space with anyone from south Louisiana?
