That wouldn’t fully solve it. You’d want two more lanes. One for return traffic, and one for emergency vehicles, as well as a place for people to escape (i.e. a sidewalk). Essentially, you end up with a street inside a tunnel, which is obviously really stupid.
I was just referring to the classic joke about highway expansion, where “One more lane” is always promised to fix all the problems of congestion and traffic. What you said does make realistic sense though.

Handy for driving under water, but not as a replacement for the roads that already have those features and already don’t work.
