Not the ones that are currently under construction like the Hampton Roads Bridge Tunnel...
And no projects that are officially dead

This will be massive. If they plan to elevate the express lanes, that would be a HUGE game changer that would be $2 billion while the one on surface will be $1 billion. I think for cost saving they should leave out the elevated plan and just go with the surface plan.
SCDOT said widening I-95 would cost about $4 billion so that's another game changer for there but I have a feeling it's years away and not a main priority.
Isn't there a massive proposal for I-10, I-45, and I-69 in Houston? Or is that already underway?
Washington's I-605 study to build a superbypass between Chehalis and Canada estimated a cost of between $42 billion and $50 billion in 2004. Obviously it was not picked up for further consideration.
I-73/I-74

I believe the project would involve a complete rebuild of downtown freeways, removal of Pierce Elevated, moving I-45 to the east side of downtown, rebuilding 4 system interchanges, and various realigning and widening of the roads involved.
MaxConcrete suggests this could cost up to $7 billion by itself. I don't think it's already underway, but it is a serious plan.
In Chicagoland, the two most expensive highway projects being recently or currently studied are the I-290 Eisenhower Expressway between I-294 and Racine Avenue, and North Lake Shore Drive from south of the Chicago River to Hollywood Avenue. Both $3B+ and who knows with today's inflation.
Widening I-95 between New Haven and NYC has to rank up there given the land constraints and the prices of land in Fairfield and Westchester County.

I didn't realize it was that much, the Wikipedia page suggests it would have only been, at most, around $19 or $20 billion.
It is rather amazing that it would have still cost less than ST3 (something I too support, for the record -- future ST4 as well).
edit: there is
this article (https://www.valleyrecord.com/news/valley-will-not-see-proposed-foothills-highway/) which suggests an
Oregon to Canada freeway could have cost upwards of $57 billion.
