The above post is somewhere between flat out wrong and malicious misinformation.
One can easily reinforce the pries of the bridge to ensure that any ship is deflected. The Francis Scott Key Bridge didn't implement these because it was deemed too expensive.
- Tuna-Fish 3y agoYou have a funny definition of easily. The impact force has been estimated as between 120MN and 230MN. I doubt there exist many bridges that can take that hit. The kind of ship impact protection that bridges usually have are not built to take a 150000t ship at 8kn.

For a critical bridge of this type, we would consider an acceptable chance for failure to be 1 in 10,000 years. And at that point why not do a cost benefit analysis of a tunnel?
