No objections from me to using T++. In fact we might sorely need it to sort out some of the problems introduced by yours truly and Calad in our latest turns (I've since viewed some videos on Youtube and now realize that my roundabouts could be constructed a lot more elegantly).
Edit:
Looking through the map there are a lot of things wrong with it, one way roads running against each other so no car can use them, missing links, weird choice, too many connections at some points, etc. I like a challenge, but t will take time to fix these things and be fairly sure that I haven't missed anything.
It seems that Calad chose to undertake the grand Central area traffic renovation project that I suggested in my journal... However, imo, the results seem somewhat mixed, if not even baffling at some points. I didn't take a look at tunnels though (the game almost blows up the crappy computer that I'm forced to use once again), so perhaps the new highway layout will make more sense with them included.
These were the main things that immediately stuck out to me when viewing the save:
-- The Great Span bridge has been renovated, and somewhere along in the process, a few blue-prints apparently got misplaced (whether deliberately or accidentally is anyone's guess...

)... So the bridge only runs in one direction now, and for some reason the traffic isn't using it at all (or perhaps the game just ran so slowly that cars failed to materialize in the minute or so that I observed it). Should be a breeze to correct; just lay another bridge in the opposite direction. ...As was the case before. Perhaps Calad wanted to correct the bridge layout (it was somewhat uneven), and then simply forgot to add the second section, being distracted by something else?
-- A few of our water pumps and windmills seem 'turned off' for some reason? Perhaps the patch did something funky here; I can't think of a reason to do this, since you can simply adjust the budget. I doubt any of our citizens care whether their electricity is produced by wind or hydro, etc (although it would be really cool if they did!).
-- I noticed that there is a **** pipe running into the ocean off of Blue Pond once again, polluting the waters and ruining the nice view. Not that it matters too much, since the houses in Avenue Falls have all been bulld--, sorry, *renovated* out of the way of the new massive highway. (I do hope that Mr and Mrs Smith got a nice compensation for their ramshackle little cabin!) Perhaps this is a jab at some of my journal entries / own demolishings (*cough* fatcatvilla *cough*)? All in good spirits, in the best Finnish way ofc.
-- I must say that the new highway project has turned our rundown, ad-hoc, chaotic-in-a-slightly-romantic way, downtown area into a full-on concrete nightmare out of Megacity One. I fully expect to see judges roaming the streets in place of police any day now (what a neat little mod *that* would be, hah!). So if Myquandro's job is to logic-ify the new road layout, mine will be to beautify it (if someone doesn't do it before me; it's a long way to my next turn after all). This said, I commend the effort though, and appreciate not overusing the new tunnel feature (for the next game we might think of some restrictions, since it's all too easy to use tunnels to solve any and all traffic problems).
-- I noticed the beginnings of an airport near New Haven; while the road connection needs some work, and it seems a little close to the mountains (from a realism pov), it's a good thing to finally get some planes going! --The airport should also serve tourists pretty well, being close to the new 'shopping jungle', i.e. Tregonwell.

That's it for now... I'd be able to comment a lot more, and more positively I'd imagine, if I was able to truly view everything in detail. On the lowest graphical settings and waiting for 5-10 seconds to move the screen every nudge though, the errors tend to be a lot more noticeable than improvements. FWIW for my next turn I will have my good computer available again.
