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.

My city has a two-way overpass over a popular pedestrian street: 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.

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