They actually already lowered the roadway once. It used to be the 11’-8" bridge. Now it’s the 11’-8" + 8" bridge (12’-2"). And there aren’t just a few signs and flashing lights. There are a lot of signs and flashing lights, including some you can’t see in this view because they’re back up that approaching street. The traffic light is also triggered to turn red if the sensors up street detect an overheight vehicle. They have done everything practical, and a few things not that practical, to prevent trucks from hitting that bridge, and trucks still hit that bridge.
This isn’t the first time a truck has bounced the crash beam up and then subsequently rattled the bridge. In the past when Jurgen (owner of the 11-foot-8 cam) has noticed this in a video he’s called NCRR to report it.
For those who haven’t seen the movie, that’s a hither-thither staff
And if you haven’t, it’s worth the watch. Chris Pine chews the scenery, lampshades tropes left and right, and the rest of the cast is equally hilarious. Special effects are pretty solid too.
Excellent first entry! However, there are delivery trucks that need to reach the other side of the bridge to make deliveries to businesses on Pettigrew St. and there is a major bus depot on Pettigrew St., too.
Here are a couple of hot takes I don’t think I’ve seen before.
Idea 1: close the road completely! there are ways to cross the tracks in either direction. I call this the “this is why we can’t have nice things” solution.
Idea 2: raise the road to the level of the tracks and make it a regular crossing instead of a tunnel/overpass. Probably prohibitively expensive.
Since the crash beam is connected to the rest of it, even though it’s designed to reduce the problem, I assume a certain amount of force gets transmitted to the structure - even if it’s not this much…
It’s not really connected. It has independent vertical support posts and trusses that reach the ground adjacent to the bridge supports but not really connected to the bridge. It’s really it’s own structure.
Ah, so really the only regular inspection that needs to be done is, “Is the beam still there? Yep.” So this would be a real mess. I wonder how long the tracks were shut down…
