Where do US highways still go through downtown, even after a bypass was built?

US 30 runs concurrently with I-84 in Oregon, so it can continue on past Portland to Astoria.  In some places it leaves the Interstate and serves as a business route through small towns.

Baltimore, Maryland:  U.S. 1 and U.S. 40.  Two others were decommissioned (U.S. 111 and U.S. 140) and one was rerouted outside the city (U.S. 301) and one was cut-back to a terminus west of town (U.S. 29).

Washington, D.C.: U.S. 1, U.S. 29 and U.S. 50.  One other was decommissioned (U.S. 240) and one was cut-back to a terminus far to the west (U.S. 211).

US 141 through Green Bay.

I don't live in North Dakota, but while researching for my trip there in a couple weeks, I found that US-83 goes through downtown Minot, although it has a bypass route around Minot. What's weirder is that US-2 has a business route through Minot, and the actual numbered route is assigned to the bypass south of the city.

US 1 uses I-93 now.

But it still goes through downtown Boston.

All of the US highways in the Richmond Area hits either downtown Richmond or downtown Petersburg, with the exception of US 460 and US 522. US 460 was shifted onto I-85 & I-95 to bypass downtown Petersburg (which is served by its business route) and US 522 ends west of Richmond.

One highway that could've (and in my opinion, should've) been shifted to local expressways is US 360. It would've been a better routing than the current route through Richmond's downtown and East End.

US 60 through Phoenix.  It probably could have been routed around most of the city on one of the loops, but it's on the Superstition Freeway east of I-10, on I-10 until I-10 and I-17 split, and the on I-17 around the downtown area, then on Grand Ave west of I-17.

There used to be a concurrence of four US routes through Phoenix and some of its eastern suburbs, but US 80 was decommissioned and US 70 and 89 were truncated elsewhere in Arizona.  US 60 is the only remaining Us route through Phoenix.  There are no US routes that still serve Tucson.

Or truncated at the I-10 and Superstition Fwy, with the Grand Ave section being US 93 instead.
