Coolidge Dam
Posted April 7, 2015, by David Johnson (dave [at] aaronswan [dot] com)

I am a civil engineer who recently inspected the Coolidge Dam bridges under contract for the owner (BIA). The bridges are currently open for vehicular traffic, not limited to pedestrians only. Although not posted now, we recommended a weight limit for the bridge. Also, the information we had showed construction was in 1928, not 1930, with reconstruction (I believe predominately in the spillway areas) in 1995. There are about 30+ additional bridges and culverts on BIA Rte 3 east and west of the dam that were constructed in the same period as the dam construction.
