The city of Des Moines says all construction work on the Grand Avenue bridge has begun again after the site was cleared following the discovery of potentially significant artifacts.
The city says the State Historic Preservation Office has determined the items found at the site earlier this week do not justify any further archeological work. Animal bones and a stone projectile point fragment were located Monday.
An archeologist came to the site to study the items and identified the broken femur bone, a mandible, and two rib fragments from an animal. The stone fragment may be from the late Paleo-Indian or early archaic period.
Work on the bridge continued while the area where the items were found was studied by the archeologist. That area is now open to construction work again.
At last word, the bridge was scheduled to be completed at the end of September.
