If you look at google satellite view you can find a few big fifth wheels on the north side of the bridge - so they made it ok (see pics). Go to google maps and you can zoom in much closer than these screen shots. I zoomed out to show location. I also looked in the parking lot of Apgar Village for a big fifth wheel but there were none present on the day the pic was taken. Bing maps satellite view shows the parking lot virtually empty. Bing street view has pics from more streets than google street views - but I did not see any other big rigs other than those below.

Also -as someone pointed out earlier - there are very few crash marks on the bridge headers on either side - meaning there have not been very many strikes. If you “drive” google street view into the tunnel there are not very many drag scars on the ceiling (see 3rd pic). I would be tempted to try it going very slow.

Seems like the campground would have pics showing some big rigs. Ask them for pics.
