The win also means that the Vikings are the first team that can apply for a 2012 Super League license.
The Raiders fought hard throughout the game but didn’t have enough to overcome Widnes, who led for most of the game.
Widnes, however, leapt into a commanding lead before the half-time interval: first it was John Duffy who went over from dummy half, Hall converting.
Widnes pressure after the restart could not result in another try, and instead James Nixon found enough space at the corner to touch down for Barrow, cutting the score to 22-12.
However, the Vikings struck almost immediately afterwards through Toa Kohe-Love, Hall’s conversion giving them a 28-12 advantage.
Both sides had chances, but it was the Raiders who finally added another try to the total, Kohe-Love’s fumble touched down by Scott Kaighan, Holt converting.
There was no way back however, and Widnes had the final say when Richard Varkulis powered his way over the line, Hall adding another two points to the final score.
