ANDERSON ISLAND, Wash. (AP) — A mechanical failure at the Anderson Island ferry dock has caused ferry service to be suspended.

KOMO reports engineers discovered a large crack in the metal beam under the ramp deck Sunday evening and forced ferry service stop, leaving some on the island unable to get off, and stranding others trying to get back home.

The ferry closure was extending into the Monday morning commute.

Anderson Island is the farthest south island in Puget Sound. It lies about 2 miles west of Steilacoom.
