I think a pedestrian overpass is a great idea for urban trails crossing busy roads.
May I suggest that an overpass is badly needed is at the Cooper’s Cove Galloping Goose crossing on Highway 14 on the Victoria side of Sooke. Highway 14 is the only commuter road from Victoria with average speeds of 60 km/ph. Adding to the danger is the fact this crossing is also on a downhill blind corner and only visible at the last moment.
Accidents here are frequent and often serious without even considering the traffic backup that occurs to Sooke commuters not being able to get home. Delays are often hours. A pedestrian overpass is much needed in this location.
