BRIDGE & OVERPASS WASHING EXTENDS THE LIFE OF STRUCTURES

Saskatoon’s seven bridges, 47 overpasses and 21 pedestrian crossings are pressure washed each spring, following the completion of the spring street sweeping blitz.  Annual washing removes the road dirt and salt that collects along the sides throughout the year to prevent corrosion and deterioration, extending the life of the structure.  Once clean, a sealant is applied to the concrete for added protection against sand and salt.  The process involves routine maintenance, and pressure washing the inside and outside walls and the bearings and expansion joints, located underneath where large amounts of dirt collects.  

Structure washing occurs overnight Monday through Thursday, from 8:00 p.m. to 6:00 a.m.; one to three locations will be cleaned each night.  For the safety of workers and drivers, and to provide access for equipment, lane restrictions will be in place during washing.  In most instances, traffic will merge to the centre lanes to accommodate the washing activities, but drivers are reminded please obey signs and pylons, and watch for City vehicles and workers. 

Tonight, drivers should watch for restrictions on the University Bridge, beginning at 8:00 p.m. Daily road restriction PSAs and Traffic Detour service alerts will advise drivers of the locations and restrictions.  

Bridge and overpass washing is expected to be completed by the middle of August, barring any unforeseen circumstances and weather permitting. 

Slow down, pay attention and respect work zones. Watch for pedestrians and work crews, and for everyone’s safety, please obey all detours, signs and barriers.
