Bridges in the California Delta
While boating in the California Delta, you are sure to come upon a bridge. Depending on the size of your boat, the tide and the clearance of the bridge, you may find that you will need the bridge to open for you in order to continue on your journey. Most bridges monitor VHF Channels 9 and 16, and you can hail them, preferably on Channel 9, with your request for an opening. Usually the bridge tenders want you within sight before they will open the bridge. Many boaters prefer to signal the bridge with a long followed by a short blast from their horn. Bridgetenders will also usually respond to a telephone call if it is during their operating hours.
Operating hours for California Delta bridges varies depending on the season, with shorter hours being the norm for winter. Some bridges are not tended during the winter, and a few are not tended at all. These bridges require advance notice if you are going to need an opening. The procedure here is to call the bridge and arrange an appointment. Obviously, you want to be at the bridge on time! During the summer, you may find some bridges operating on scheduled openings on weekends and holidays.
