Yuma, Arizona A construction crew in southern Arizona discovered an unexploded howitzer round while working on a road. EOD identified the ordnance as a 155 millimeter howitzer used during WWII and the Vietnam War.
It was the second round found on the road improvement project that began in February. The first was found in April in the same location. The road was closed for several hours as experts safely removed the munition.
Officials say the area was once part of the Desert Training Center, also known as the California-Arizona Maneuver Area, founded in 1942 for desert warfare training. Both rounds "were found more than one mile outside of YPG's boundaries, and have nothing to do with the proving ground's present-day testing," said a Yuma Proving Ground spokesperson.
