Free Beer Friday Guess the City

I have a surprisingly extensive highway system, none of which actually effect the city center, which buffers it from the highway and industrial riverfront via a rigidly geometric ring road, which replaced city walls. Internal to the ring road is an equally rigid orthogonal grid pattern and extremely pedestrian friendly with numerous carfree roads.

I may or may not have friends and relatives in a recent post. Who am I?

(ed. note: as always, first correct guess in the comments and find me at happy hour gets a free beer. Except for reigning champ Toby who apparently is accepting Carbon offsets instead of beer.)
