Central neighbourhoods shorten the actual distance but can still hit a bridge at peak times, since the Broadway, University, Idylwyld and Circle Drive bridges are the main crossing points the City of Saskatoon's traffic patterns funnel through. Silverspring and Stonebridge sit close enough to Circle Drive to reach several employment areas without needing a central crossing at all.
Where you actually work matters more than which side of the river you live on, since a short drive to one part of the city can be a long one to another regardless of neighbourhood reputation.
