It's worth anyone either driving to the game or getting public transport via the city centre to check out the below link to make sure your usual route isn't impacted by the cycling world championships. The area directly around Firhill is largely unaffected but one of the race routes includes parts of Maryhill Road north of the stadium, a small bit of Great Western Road, Cleveden Road and Byres Road so traffic might be a bit mental elsewhere due to the road closures.
