There are a lot of places I have found where a concurrency would become useful that are not. Places like US 321 in Hardeeville, SC that should really end at I-95, or US 206 in Milford, PA should end at its parent (or even I-84 with a short overlap with its parent as well), and there is US 31 in Spanish Fort, AL which should overlap with US 90 to end and connect to I-10 at Exit 35.
Then you have I-59 which should be co signed with I-24 being it terminates not too far from I-75. Being the connection is very popular among motorists going from the Northeast to the Gulf States for tourism and commerce the idea might be very useful in this proposal.
Any useful short concurrencies that should be created to make easier connections in small concentrated areas?
Extend US 209 over the Kingston-Rhinecliff Bridge to end at its parent US 9.
Extend CT 4 to end at the Farmington/Asylum Ave junction in Hartford.
Extend US 4 over NH 4 to connect to and take over ME 4.

I did not place in in fictional highways because I am referring to an existing road network that roads should be altered at a given intersection. The connection I was looking for is not a long haul route, but just a small alteration as US 31 would only be extended not even a whole mile. US 206 would stay within a corporated town ( or borough as PA identifies it as), however all using existing roads for just a short period. Yes, I might of overdid it with I-59 as that is several miles, but it does not require new building or long extensions.
Anyway, I did not want long distance ideas as that already was (and is in other threads) just intersection (or intersection modifications) that can make two nearby routes more accessible.
I've felt that MN 39 should not exist, and MN 210 should just be extended eastward over it.

When designated, US 4 south of Hudson Falls and US 9 from New Jersey to US 4 was US 9E, which was on equal standing with US 9W (which used current US 9 north of Albany), thus US 209 once ended at its parent. There's not much of a reason to change the number on people, because NY 199 west of US 9 is already on the NHS and it would do nothing more than please a few roadgeeks and cause confusion.
Although I agree on that one, that extending US 209 would only add confusion, the idea still would not hurt even though it would please some of us here more than the non road geek public as to them 209 is just a number. Plus not many head to Albany via US 209 to US 9 anyway because the Thruway handles that now.
However, making a duplex with NY 199 would not hurt either.
I-355 or I-290 to lake-cook road (later IL-120 / I-X94). Why should the main flow of highway have 3 number changes.
How about CA-24 get extended where I-980 is at in Oakland.
I-980 is one of 4 freeways in the Bay Area where a 3di does not touch I-80 the parent route.
I-238, I-380, I-280 and I-980.
OH 38 should be extended north from its current terminus in the middle of Marysville, along OH 31 (which may be truncated accordingly), to end at the bypass which carries US 33, US 36, and OH 4.
OH 104 in Columbus should be extended northeast along James Rd to meet I-70.
OH 180 near Chillicothe should be extended west along a new road to meet US 23 at its interchange with OH 207, and then maybe along OH 207 to meet OH 104.
OH 750 should be, near Dublin, extended west across the Scioto River via Glick Rd to meet OH 745; and, near Westerville, extended east along Polaris Pkwy to meet OH 3.
OH 47 at Waldo should maybe be extended northeast along OH 98 to US 23. Alternatively, trailblazers between US 23 and OH 47 via OH 98 (for 47 to 23N and 23S to 47) and OH 229 (for 47 to 23S and 23N to 47).

Good point. I-355 to Lake-Cook Road would make the most sense as well as extending I-88 to the Circle Interchange. IMHO, the remnant of I-290 could then be I-588 (or I-188, but I'd avoid I-388 as it would meet I-355).
Over the next few years, PennDOT will be upgrading the Freedom Rd. corridor from PA-989 west to PA-65/Ohio River Blvd.... With the improvements they did years ago east of PA-989 toward Cranberry, this would make a logical westward extension of PA-228 to PA-65.
