While Googling, I came across a pretty cool bridge plan
made by ancient
back in 2009. The front is a little inaccurate, but I figured it was close enough to see if the bridge and plaza would really fit inside a 2380' Enterprise. Going by a guesstimate bridge width of 50', and corridor height of 8' (giving a plaza width of 60'), they fit!
Although I'm not so sure there's room for those corridors around the bridge we see. But it's close enough for me
