Extreme Cantilevers

While looking at Street View for some overhead sign examples to post in another thread, I came across this completely unexpected example of an extremely long cantilever sign bridge: I-515/US-93/US 95 south at Casino Center Blvd exit in downtown Las Vegas. This extreme cantilever is unique in that it spans 5 lanes of traffic, and is supported from the median instead of the right shoulder due to it connecting to a full sign bridge for the opposing direction. (For context, this sign structure is new due to a recent project that shifted the median wall on the viaduct to make room for an additional southbound lane. The original sign structure was located in the physical gore with a post in the gore, which is a far less safe design many agencies no longer install. I'm guessing NDOT couldn't work out a right of way accommodation with the adjacent casino to install a support post that would allow for a full bridge where the new sign is located.)

I've never seen anything like this before, and was wondering if there are other examples of cantilever sign structures that extend over 3 or more lanes.

Not a cantilever sign structure, but given the title of the thread, I thought this cantilevered sidewalk was a little interesting, in Ketchikan, AK:

I came across a couple Vermont specimens while on a recent roadtrip, although not as extreme as the OP's:

This is unusually wide for a Caltrans installation:

That's so ridiculous, it almost looks Photoshopped.
