A few recent examples (within the last 5 years or so):

Tilley Bridge, connecting the south end of Trinity Park in the foreground to downtown Fort Worth in the background


Clearfork Main Street Bridge (the span on the bottom is for bike/pedestrian traffic only, and hangs from the main traffic bridge)


West 7th Street Bridge connects the north end of Trinity Park to downtown, with the bike/pedestrian path separated from motor traffic by the structural arches of the bridge


I had trouble finding a good picture of the Hulen Street bridge, but here's an aerial view. It has a 10 or 12 foot sidepath on a raised curb on the east (left) side of the bridge, and spans the Trinity River, a major rail yard, and a new tollway. Despite its length, it's an easy bicycle crossing. (In the extreme upper right of the picture you can also see the Clear Fork Main Street bridge crossing the river.)
