You probably wouldn't believe how awful it is to break down on that bridge! If someone wrecks or stalls ahead of you, and they can't manage to pull over to the shoulder, the whole bridge is shut down in that direction, usually by traffic that just has to come to a complete halt after the wreck. Even if you manage to pull over to the shoulder (and not all areas have shoulders) you are on a shoulder that is barely as wide as your car, so you are incredibly close to cars and trucks flying by.....don't stick your head out the window, that's some good advice.
A tow truck usually has to come from the opposite direction---and this is a divided highway, with a big drop down to open water or swamp land in between. Turnarounds have been added, but they are blockaded closed and can only be opened by police, so you have to wait for LE and the tow truck to show up, open the turnaround,and wait more time for them to get to you, hook you up and tow you out of there. It literally can take HOURS.
I personally know of two car stalls which resulted in the deaths of all the occupants of the vehicles when they were slammed into by eighteen wheelers traveling at well over the speed limit.
