I guess, but the amount of space and inefficiency that building a highway that literally runs over 1 block over the middle of a city would seem to be not at all worth it.

it wouldn't be a highway, it's called an overpass. and they're quite common.

  An overpass tends to make the area underneath it pretty grim: surrounded by concrete with little natural light. I can't think of any examples of a nice shopping street with an overpass above it. An underpass works well, but is likely to be much more expensive.

    Also there’s two levels of subways running beneath market street so an underpass wouldn’t be feasible

    My city has a two-way overpass over a popular pedestrian street: https://cdn.olhares.pt/client/files/foto/big/980/9808889.jpg https://cdn.olhares.pt/client/files/foto/big/980/9808889.jpg I think it works well as long as the overpass isn't too wide. Also, using colours and stone instead of raw concrete on the outside helps.
