A more practical and feasible 'big' project would be our own 'Panama Canal', that could run along the southern border from CA to TX. Once that's done, build another along the northern border from WA to ME. Dump all the excavated dirt in France, just for the hell of it.

As long as we have all that dirt, why not just fill in the ocean from Nova Scotia to England. Wouldn't a land bridge be kewl?

We could use surplus nukes to dig that southern border canal pronto. El Paso would not be a big loss, but turn slightly south around San Diego.
