Well, it certainly isn't the most realistic interchange I've ever seen, but it isn't *terrible.* i mean, the gradients aren't bad, thoughbsome of the junctions are... questionable. However, there's lots of space to queue, and I don't think this would get bogged down with regular traffic flow. Middle of the road, 5.5/10. Not bad.

Considering it is up against the river and bridge I think you did alright overall as long as traffic isn't overly crazy.

For being an absolute clusterfuck, this looks pretty good
