I forgot to mention that the fireworks near Yokohama Bay Bridge and Rainbow Bridge don't seem to be animated unlike the other ones you could find in other parts of the map as @TrueBest stated.

I gotta say, this has to be one of the best map mods in the game. It's a 1:1 port of every expressway map from WMMT and I love it!

Though there's some problems on the mod like missing map objects like some of the skyscrapers in North Yokohane Route and some of the towers in the industrial area within the Wangan Route, and the map quality being reduced if you replace the map textures with the ones provided (and unfortunately, they get cut off by the water depths around the vanilla map's edges). There's a stray barrel barrier on Takebashi JCT (C1-Ikebukuro Junction) which seems out of place but thankfully they don't have collisions, though that fake barrier should be removed. Kinda wish that the barrel barriers in the map don't have collisions since some of them seem to block off Parking Areas or places that you could go through like the collisionless Arrow Barriers.

It's still neat to port all of this and I commend you for this amount of work done. Great job!
Hopefully we could see more work like this down the line. Hoping to see WMMT's Mt. Taikan (Hakone Turnpike) too.
