People walking, riding bicycles and in automobiles stopped in disbelief to watch a sailboat crunch into Bay Farm Island Bridge about 6:30 p.m., last Sunday evening. 

If the mariners aboard the sailboat were  hoping to alert a bridge tender to open the bridge, they were too late. According to a spokeman for the  bridge office at the Alameda County Public Works Department, the Bay Farm Bridge is tended on Sundays from 8 a.m. to 5 p.m., a fact not only clearly marked on the bridge, but something that mariners should be aware of as well.
