4TH AVENUE FLYOVER REHABILITATION: Reopening for Stampede

The 4th Avenue Flyover will be reopening to two lanes for Stampede

Originally built in 1982, Calgary’s longest bridge structure, the 4th Avenue Flyover needs major repairs and improvements.  It has been serving motorists accessing Downtown Calgary daily, for 42 years.  As one of the main access points to downtown, the familiar flyover typically carries two lanes of traffic to 3rd Street S.E., but has been reduced to a single lane since construction began this Spring.  

Ahead of Stampede, the flyover will be restored to two lanes for the duration of the Stampede from July 5-14 to reduce congestion and improve mobility as we welcome thousands of visitors to Calgary. 

The bridge will fully close overnight July 3-4 and July 16-17 from 9 PM to 5 AM to transition it from one to two lanes, and back again. Please follow detour signage if you are travelling through the area during the closure, for your safety and that of construction crews. The bridge remains a construction zone, so drivers should expect uneven pavement and narrow lanes.
