MOOSE JAW – The City of Moose Jaw advises that the Thunderbird Viaduct (Fourth Avenue bridge) will be closed to vehicular traffic beginning Monday, January 17. Pedestrian walkways will remain open.

The closure is necessary for crews to install a new catcher beam underneath the north end of the bridge to support existing bridge infrastructure. During the closure, crews will also perform deck exploration work to determine the condition of the reinforcing steel.

The work is anticipated to be complete, and the Thunderbird Viaduct reopened, by Friday, January 28 (weather permitting).

All area businesses remain open, and drivers are asked to use 9th Avenue NW or 1st Avenue NE to access south hill.

The City of Moose Jaw reminds drivers and pedestrians to obey posted signage and exercise caution in work zones for the safety of everyone.
