Roads do help wolves. Wolves are far more mobile because of them. Wolves have adapted their hunting style to trotting down roads until they wind an ungulate then they go kill it. They are able to cover far more ground this way than going through deep snow and thick bush, swamps, mountains, etc until they wind prey. Their hunting is more successful, the more successful their hunting the more successful their breeding. We have more wolves than ever and they are more successful when hunting because of increased mobility and travel speed. Telemetry studies have shown they move far more distance on roads preferring to use them instead of traditional routes they used before roads. Saves cutting through bush, swamps, mountains. It is simply an age old adaptation of wolves in winter travelling on lakes and rivers making good time until they scent a victim, they now have adapted to using the same hunting technique but using roads to do it year round. Roads are everywhere and lead to cut blocks that draw ungulates. Lakes and rivers are not everywhere and travel on them is pretty much limited to winter for wolves. It allows a higher number of wolves far more mobility to hunt an expanded territory through all the seasons they previously may have not used as much or at all.
