The City of Moose Jaw's Parks and Rec department remounted a historic sign on 4th avenue bridge on Monday.

The Thunderbird Viaduct as we know it now was originally named the "Fourth Avenue Viaduct".  The historic sign with that name was remounted on the green fence near the the bridges northwest corner.  The sign was part of the original project when the bridge was opened in 1929.  The sign fell off a number of years ago, and was remounted as part of the South Hill Community Association's ongoing refurbishment of the bridge.

In October of 2017 a plaque, which includes the bridges official name, "The Thunderbird Viaduct", was unveiled on the southeast corner of the bridge by members of the South Hill Community Association.

At a ceremony that day, south hill spokesperson and  City Councillor member Crystal Froese said, “Bringing forth the original name (Thunderbird Viaduct) came from our Local Area Plan".  "We hope the Thunderbird Viaduct name will be utilized in reference to the bridge, as per the wishes of Moose Jaw City Council in 1952".

That council, led by Mayor Scoop Lewry, approved a motion to adopt the Thunderbird Viaduct moniker to recognize the history of Indigenous tribes that were native to the Moose Jaw area.
