NH 114 and MA 114 both run NW-SE, and they're pretty well lined up, but with a 20-25 mile gap. This is a complete coincidence; there was never a plan for them to be a single route.
CT 106 and NY 106 appear to be lined up, but with the Long Island Sound in the way.
Examples must be unintentional.
(Non-state routes welcome, but I expect most of the examples to be state routes).
The only state highway in Michigan that lines up with a state highway in another state with the same number is M-49 which becomes OH-49 in Ohio. The only other ones of course are Interstate's and US highways. I'm not sure if this was intentional or not considering Michigan doesn't do it anywhere else.
Before there was US-41, the old M-15 on that corridor connected to WI STH-15.
And of course there was the old IN/MI/OH 120.
But I don't think that's what this thread is all about. I think it's more of, "Hey, I saw two highways with the same number near each other in adjacent states."

And same direction. US 20 (in MA) and CT 20 are close, but they don't qualify as they are parallel and wouldn't make sense at all as a single route.
For unintentional, a quick glance doesn't show anything for Colorado. There are four state highways (17, 23, 71, & 96) that continue with the same number in the bordering state, but all I assume are intentionally done so. I don't see any other highways that are disconnected, nearby, and have the same number.

Good examples of what the OP asked
NC 4 and VA 4
MD 24 and PA 24
OH 618 and WV 618
AL 13 and TN 13
TN 75 and VA 75? Might be too far apart
GA 59 and SC 59 appear to qualify but they were once connected.

Virginia continues state routes with many of its neighbors. 160 and 80 for Kentucky, 70 for Tennessee, a whole bunch for West Virginia. I'm not sure how the North Carolina examples shown above could be considered anything but intentional.
As for the OH/WV example, West Virginia renumbered its old portion of US 50 in Parkersburg to match the route on the other side of the river. Similar to how WV 7 was extended across the river from its signed terminus at WV 20 to connect to OH 7.
How would one consider KY 80 and MO 80 in terms of this thread? They are across the river from each other, but there's no connection.

I thought of MO 80/KY 80 but don't know if KY 80 was intentionally run over there because of MO 80 or not.
I should remove OH 618/WV 618 as while they don't connect it probably is intentional that WV numbered it that way.
Any number that keeps across state lines should be disqualified unless each state was "forced" to have its side numbered that way by some other system. All Virginia crossings that retain their number was an intentional effort in Sept 1940 to do so.
MN 48/WIS 48. Sometimes I forget they don't connect.
