7th Street Trafficway Bridge
Posted June 13, 2016, by Nathan Holth (nathan [at] historicbridges [dot] org)

I almost gave up trying to get photos of this bridge... but last minute found that you can get photos (it is fenced off but with gaps big enough for large SLR lenses) at the end of 5th Street where it hits the levee, NE Quadrant around bridge.
