What state has the most different US highways? Mainline routes only - business highways, alternate highways, and directional splits don't count. I'm going to go out on a limb and say Georgia.
Illinois has 20, Georgia has 23, Tennessee has 29, and Texas has 37.
Pennsylvania looks to have a bunch of them.

22 in the Keystone state, not including US 6N.
Virginia - 29
S. Carolina - 23
N. Carolina - 34

Tennessee has 30. US 58 now enters Tennessee. Of course US 63 no longer enters Tennessee.
I should have known that the very large Texas would have the most US highways based on its gigantic size.
Here's a related question: what state has the most US highways per square mile? I guess that Georgia would be a contender.
What is a shame that a city like New York, the largest city in the US, has only two US routes within its limits. Not even an east- west highway you figure with Long Island being to the east would have them as well.
You would figure that all roads from all directions would lead to the big city, but only from the north, south, and west has New York tied in from the rest of the world. No east or even NW has a US route coming in to serve it.
Heck New York as a state of its size does not have that much in general. 10 in all and 11 if you consider US 9W as a route in itself.
New York state wasn't very receptive to US routes in the beginning, which is part of the reason there are only 2 in NYC. Many US routes ended at the NY border.

That would explain why NY 17 was never a US route despite it being a major corridor across the southern tier and the entire upstate's south perimeter.
US 46 is one that ends at the state line and the defunct US 106 that could have used NY 52 and returned to its parent after ending at the State Line at the Delaware River. Also US 220 that might of continued to meet its parent someplace in the state that ends just shy of the border.

Looking at this map...

...I agree GA could be a contender, as well as SC, NC, and VA. But you'd also have to take a look at the states to the northeast that are geographically smaller.
Rhode Island has 3 (they are 1, 6, and 44), and it is tiny.

Also no 3 digit routes and no terminuses within it. Those three routes transit the state with no children.

New Jersey could very well be a contender for this. Its got:
US 1, US 9, US 22, US 322, US 30, US 130, US 40, US 46 ( :bigass: ), US 202, US 206
Unless I've missed one, it has 10 US Highways and New Jersey is the 46th smallest state (geographically) in the nation.
New Jersey has 7.4 times the area of RI but only 3.3 times the number of US routes, so RI is more US-route concentrated than NJ
Delaware has 6 (9, 13, 40, 113, 202, 301) and is only about 1.8 times larger than RI, so Delaware is slightly more US-route concentrated

Rather than looking at the number of US routes per state (which can be somewhat arbitrary), I think a more accurate measure of US route density per state would be a ratio of the total US route mileage in the state, compared to the square mileage.
Connecticut has US Routes 1, 5, 6, 7, 44 and 202.
There's only three areas I'm aware of where US Routes are multiplexed:
Danbury, where US Routes 6, 7 and 202 are concurrent with I-84 between Exits 4 to 7. US Routes 6 and 202 are multiplexed from I-84 Exit 4 west to the New York border. US Routes 7 and 202 are multiplexed for a distance from I-84 Exit 7 northward.
Hartford/East Hartford town line, where US Routes 6 and 44 are concurrent with I-84 over the Bulkeley Bridge (spanning the Connecticut River).
Manchester/Bolton, where US Routes 6 and 44 are multiplexed when heading west from I-384's east end.

Texas would win that one hands down.

I don't think so. I think it would be one of the aforementioned states along the Atlantic coast.
California has 6, 50, 95, 97, 101, 199, and 395, though only 101 and 395 have any impact on mileage in the state. And the only place where there's a US route multiplexed with an interstate is in Needles.
Michigan could be a contender for highest density of US route freeways (that aren't concurrent with Interstates), since you have large portions of 10, 23, 127, 31, and 131 by themselves that are freeway. No way is it going to hold any other US route related record... well, except that 102 was supposedly the first US route ever to be decommissioned, but folks here have disputed that.

Interstate/US route concurrencies in California: there's also I-10 with US 95 approaching the Arizona border and unsigned I-305 with US 50 in Sacramento.
Former: I-80 with US 101 (Central Freeway), I-80 with US 99E (today's Route 51/Business 80), I-5 with US 99 (various spots), I-5 with US 101 (south of Los Angeles), I-15 with US 395 (Hesperia to San Bernardino) and US 66/91, I-80 with US 40 (various), I-80 with US 50 (San Francisco Skyway), I-80 with US 99W (West Sacramento), I-10 with US 99 (San Bernardino Freeway). Unclear if I-5 was ever signed with US 6 in the San Fernando Valley
Former that never was signed: I-480 with US 101 (Doyle Drive), I-105 with US 101 (Santa Ana Freeway/downtown slot)

Here you go. US Highway Mileage numbers are from CHM, which I believe correctly accounts for concurrencies (not double-counting), and land areas from Wikipedia.
Among the "not tiny" states, it looks like Virginia and the Carolinas love their US highways the most. New Jersey, too, unless you count it as tiny.

5 and 44 overlap for a few blocks in East Hartford.
And everyone forgets about CT's 7th US Route...

I had a feeling CA would come in last on the density count. This is what happens when you decomission viable US routes like 99 and 60 and turn them into state highways.
