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.
An underpass works well, but is likely to be much more expensive.
