I believe the following would count:
(WA) SR-526 - formerly part of SSH 1-I, was routed over 5th St, Mukilteo Blvd, and SW 41st St. from Mukilteo to Everett, to end at US 99. In the early 60s it was part of the highway re-numbering, and given the designation of SR-526. Later in the decade, it was moved from the routing above, to SW 84th St./Casino Rd. from SR-525 to US 99 (and later I-5), then a new expressway/freeway alignment was built to facilitate better traffic movements around Boeing's Paine Field facility. In around 1999, the connection between the expressway portion and SW 84th St. in Mukilteo was realigned, to feed most traffic to the newly constructed Paine Field Blvd. (SR-525 Spur), preparing for planned rerouting of SR-525 to the ferry terminal. As a result, what was once a single road route, now has a traffic signal and turn to follow the route, something it never technically had previously.
(WA) SR-529 - SR-529 was a replacement for US 99, when it became SR-99 and was truncated to SR-526/SR-527/I-5 in South Everett. It ran from I-5, along Pacific Avenue to Broadway (former US 99), then followed Broadway back to I-5 in North Everett/Marysville. When NS Everett was built, the route was changed to follow Pacific Ave. to Marine View Dr., which would connect at the main gate to the new Naval Station. The routing was later changed to officially use Everett Ave. from I-5 to Marine View Dr, as it was better able to accommodate the traffic volumes. However, the interchange between I-5 and Everett Ave is directional, and only connected to facilitate movements from and to the north. So Pacific Ave was designated as SR-529 Spur, however it is unsigned, aside from the BSG indicting "To: SR-529", with no signs on the streets to facilitate connection to SR-529.
(IN) SR 25 around Delphi Indiana - This route has had no fewer than 3 routings through the city, and now bypasses the city on an Expressway Alignment. The route entered originally from the East, over what it now Samuel Milroy Rd., before following Monroe St. to Washington St. There it met with the old alignment for US 421/SR 39/SR 18, before exiting using the previous alignment to the SW. Later it was routed over the entirety of a newly built Samuel Milroy Rd., to what is now Main St., and followed that through town. Later Main St, was extended to the east, bypassing Samuel Milroy Rd., and providing a straight road to the city limits, before turning North to connect to the ROW, and re-aligning the NE end of Samuel Milroy Rd. (then called Old 25). Main St. was realigned to connect to the newly constructed Hoosier Heartland Highway around 2008, routing SR 25 along the new alignment to Main St, then through town, and out to a newly constructed connection with the HHH SW of the city, before being fully realigned to bypass Delphi around 2011. In the case of Monroe St. and Samuel Milroy Rd., there is little evidence on the ground that the route once used the roads, aside from some extra curbing and width on Monroe Rd., and Samuel Milroy Rd., literally being called Old 25 for almost 40 years.
