Bow River Bridge Rehabilitation Program 2023 Project Description :*** Addendum #1 has been posted on September 5, 2023 *** *** Addendum #2 has been posted on September 6, 2023 *** The Town of Banff (Town) invites interested parties to submit Tenders for the Bow River Bridge Rehabilitation Program 2023, in Banff, Alberta. This year’s bridge rehabilitation works include masonry repairs, architectural repairs, concrete repairs, epoxy crack injection, bearing refurbishments, girder end paint repairs, and in-stream riprap installation at piers. The Town of Banff, located in Banff National Park, is part of the Canadian Rocky Mountain UNESCO World Heritage site. The Banff Bow River Bridge is a critical piece of infrastructure for the Town for multiple reasons. Foremost, this bridge is the sole vehicular land crossing, and only one of three pedestrian and active mode land crossings, over the Bow River to the south of Banff within the Town limits. Moreover, this bridge was designated a
municipal heritage resource in 2016, by the passing of Bylaw 372, and is considered by many people to be an iconic historical landmark of Banff that features prominently in tourist photos and postcards. The Banff Bow River Bridge carries Banff Avenue over the Bow River, with the nearest intersections being Buffalo Street to the north and Cave/Spray Avenues to the southwest/east, and with the Bow River Trail and Glen Avenue passing under the north and south ends of the bridge respectively. This unique community strives to consider their location and surrounding environment in everything they do. In order to sustain and preserve infrastructure assets, regular improvement and maintenance is essential. The Banff Bow River Bridge is now over 100 years old with the original construction completed in 1921 and the most recent major rehabilitation works completed in 1986/87. This tender package is the second and final tender to be issued as part of the current Bow River Bridge Rehabilitation Program which started in 2022.
