Sturgeon Bay Bridge Procedure

[carbonrobot]

There are three bridges in Sturgeon Bay that must be opened to pass through if you are over 40ft vertical. What is the opening procedure for the three of them? Two of them are adjacent and it looks like need to be opened at the same time. Do you just VHF 13 "Michigan Street Bridge" or something? Or is it horn based?

Ok, I found the information referenced in the US Coast Pilot 6. Amazing how difficult it was to google for this.
