    We build bridges to avoid the necessity of building tunnels and we build tunnels to avoid the necessity of building bridges. We build bridges and tunnels because we have a lot of tax dollars to spend.

    Safety. A bridge is safer than a boat or swimming. On intersections of freeways and surface streets, the high speed traffic of a freeway and low speed cross traffic of a surface street don't get near each other.

    A tunnel is safer than climbing up and down mountainsides, or going over a "Channel" or a "Bosphorus". On subways, there is not much chance of hitting street traffic or pedestrians. Buses and trams have that problem.

    And as pointed out by others, going over or through is faster than around.

    To cross stuff.

    Before the New River Gorge Bridge was built, to drive to the bottom of the gorge and cross a small bridge at the bottom near the river took 40 minutes. Crossing the New River Gorge Bridge, which spans the gorge at the top, takes 40 seconds.
