It still needs to be rebuilt to true all-season capabilities.
I think the maintenance crews working on the road later this month plan to take care of unfinished business left over from last November when the road was opened (mainly adding and compacting gravel), not exactly a full rebuild. Once they're done, I'll check in with the rental car company on whether they'll let me drive one of their vehicles to Tuk.
The current conditions between Inuvik and Tuk sound, from the road conditions site, no worse than the Dempster Highway from the Yukon border to Inuvik, which has been open for decades. So maybe some progress has been made already on getting the Tuk road tourist-friendly.
CBC reported yesterday that the highway was being reopened, but with a weight limit of 5000 kilograms (about 5.5 tons) which will keep off most trucks for now. The accompanying photo (which might have been taken before the pre-reopening work on the highway) is not encouraging, showing lots of mud and deep ruts.
