DES MOINES, Iowa (AP) — The State Historic Preservation Office has determined that no more archaeological work is needed at a bridge construction site on the western edge of Des Moines.
An archaeologist was called to the Grand Avenue Bridge site after workers found potentially significant items on Monday.
The archaeologist examined animal bones and a stone fragment that could be a prehistoric artifact. Officials announced Friday that no more archaeological work was needed.
The examination led to worries that an already delayed project would be pushed back further, but crews were able to work on the east side of the bridge.
The bridge spans Walnut Creek and links Des Moines and West Des Moines.
The bridge has been closed since March and officials hope to open it to traffic at the end of September.
