you can have both, but it is rare...
and it depends on your definitions of course  (e.g. you might call it an enclosed bridge or sth. like this). In engineering standards, tunnels are not only dug structures but also completely enclosed linear ways with certain length (e.g. in Germany it’s from 80m onwards according to concrete standards, IIRR), which can also in exceptional cases lead over a bridge.
