A tunnel goes underground, an underpass goes under a bridge.
An overpass goes over another road, but an underpass goes under another road.
An underpass
Yes, there was. In 1923 they constructed the subway approach to the MacArthur Bridge (underpass), under E. Jefferson from the Boulevard, which cost $467,000. In 1984, the bridge underwent an $11.5 million renovation project, which was completed by 1986. They also redesigned E. Jefferson and E. Grand Blvd. That once infamous underpass/subway (or tunnel) was filled-in and removed during the renovation. Here is a link with information: http://www.detroittransithistory.info/AroundDetroit/BelleIsleCoachStation.html It also shows a photo of cars leaving out of the underpass.

No. An underpass provides no protection from flying debris, the main killer in a tornado. Also the bridge itself can have a wind tunnel effect, so that the winds from the tornado actually speed up when going under it. A ditch is a better option than an overpass, but even then it is only to be used as a last resort.
