Check out maps.me. It uses OpenStreetMap data. And other apps using OSM also offer alternative maps that are updated more frequently based on user input. Occasionally those are more up to date than Google and other maps.

However those maps tend to tell us only whether a road is finished or open, not necessarily the condition.

Checking bikepacking and touring groups on Facebook and elsewhere. They'll often have the most up to date info on road conditions based on direct rider experience.

Other popular apps with up to date info:
Komoot
Map My Ride

chasingwatts.com website and app (iOS only at the moment) is new to me. I'm not familiar with it but a couple of local groups have switched to it for organizing group rides when it's necessary to make quick changes to accommodate road conditions.
