Maryland did this all the time, with floating segments of state highway connected by county-maintained segments of varying quality.  Most of these were mopped up by 1990, with the entire road either unified into a one-piece state route, or downloaded to the county in exchange. 

Off the top of my head, MD 97, 138, 439, 495 & 623 were all once multiple segments later joined.  MD 37 and 567 stuck around until 1999 as fully signed floaters.

Still, it's amazing how often there is an 'end of state maintenance at an indeterminate point' because that's where the segment ended in the 1930s.

Md. 192 (Forest Glen Road) in Silver Spring, Montgomery County, exists today only west of Md. 97 (Georgia Avenue).

But  at one time, it existed in several chunks east of Md. 97 as well.

It continued past Md. 97, passing Holy Cross Hospital, and then the state maintenance ended at Sligo Creek Parkway.  Then there was a county-maintained section continuing east to Dallas Avenue, where state maintenance resumed, only to end again, as the road turned to the north at Stirling Road, where state maintenance ended and the street became Sutherland Road.

The easternmost part used to tie directly into U.S. 29 (Colesville Road) prior to about 1960, when the interchange for U.S. 29 and I-495 was built, forcing Md. 192 to "deflect" into Sutherland Road.

I wonder if the end of state maintenance at Sligo Creek Parkway might have had something to do with the (long-cancelled) Northern Parkway, which was to run from the intersection of Md. 97 and Md. 390 (16th Street), under the Capital Beltway near Holy Cross, then almost straight north parallel to Sligo Creek Parkway, ultimately crossing the Outer Beltway (now Md. 200, InterCounty Connector) between Md. 182 and Md. 650?

Found something unique about Louisiana once more... the older routes, pre-1955, were labeled with a -D or -E or -F afterwards. These routes were added and deleted at a whim, and many copied themselves over and over again. I've come across four LA 7-D routes for example, three LA 7-E, two 7-F, no 7-G, and one 7-H.

OK 74 was once a single highway, but the middle section was decommissioned.

Digging into the history, you see Oklahoma's double highways are about half "middle section decommissioned" and half "the second half was designated to match some other state's route".

OK 15 is another good example of a highway that had a middle section decommissioned.  The middle part is now US 412.

OK 52 is an odd duck. As best I can tell the middle section was decommissioned because it was easier to do than paving it.
