Weighted network analysis

Is it possible to do a weighted network analysis in arcmap or pro? What I mean by that is I have a road network with hazards on that network, and I am wondering if it's possible to determine the shortest route through that network while encountering the fewest hazards using built in tools. I don't do network analysis very often, and I'm not 100% sure it can be done in network analyst.

Network Analyst supports loading in "barriers". These barriers can be absolute or relative (scaled cost). So if your hazard areas are polygons, then load then as scaled cost barriers with a high scale cost like 10. Now find a route between your start/end locations and it will avoid these areas unless there is no other way to get to the destinations.
