I mean, the only other time I've seen it happen is on WA 504 where WSDOT finally gave up on rebuilding it to Tri-Cities after signing it as "temporarily closed at Johnston Ridge" from 1982 until the Johnston Ridge Volcanic Observatory was remodeled.  What feels more plausible is that DD actually does make it to Coney Island but they just repaved part of it or changed materials in order to deal with whatever's going on below the surface of the highway or to save cost.
