Template:Infobox Bridge

The Traffic Bridge was a truss bridge that spanned South Saskatchewan River, connecting Victoria Avenue to 3rd Avenue South and Spadina Crescent in Saskatoon, Saskatchewan, Canada. Opened October 10, 1907, it was the first vehicle bridge in Saskatoon, replacing an unreliable ferry service. The promised construction of the bridge was considered a prime factor in the amalgamation of the towns of Saskatoon, Nutana and Riversdale. The Traffic Bridge was the only road bridge in Saskatoon until 1916, when the University Bridge was completed. In 2010, the bridge was permanently closed due to severe corrosion and has been partially demolished.

Names

The bridge is known both popularly and in official correspondence as the Traffic Bridge, originally distinguishing it from the QLLS/CN railway bridge just upstream and later becoming a proper noun in its own right (the railway bridge was built in 1890 and demolished in 1965 when the rail line and downtown yards were removed; the Senator Sid Buckwold Bridge now crosses the river at its former location). Although it is Saskatoon's oldest bridge, it was the last one to be formally named. On January 22, 2007, Saskatoon City Council voted to officially name it the "Traffic Bridge", on the recommendation of the Municipal Heritage Advisory Committee, as a way to acknowledge its historic character and the vital role it played in the city's early history.

The bridge has been referred to by various names since its construction. The most popular name is Victoria Bridge, given that Victoria Avenue runs right up to the bridge's east end. It has been called the 19th Street Bridge, although 19th street actually passes a block north of the bridge and connects with the northwest end of Broadway Bridge (this name made more sense prior to the construction of Broadway Bridge, when the streetcar line came down 19th street before turning onto the bridge). Due to its colour, it has also been called the Black Bridge, although its most recent painting is a rather dark grey. It is also sometimes called the Iron Bridge and even the Short Hill Bridge after the Short Hill, down which Victoria Avenue comes.

History

The Traffic Bridge came into being when residents of Nutana agreed to merge with the town of Saskatoon and the village of Riversdale to form a city. As a condition of their joining with the other two communities, they demanded that a bridge be built for foot and vehicular traffic. Up to then, the only way to cross the river was on an unreliable ferry, or a difficult and sometimes dangerous walk across the QLLS railway bridge. The province provided funding and John Gunn and Sons was selected as the contractor. On October 10, 1907, the Traffic Bridge officially opened.

Less than a year after it opened, on June 7, 1908, the bridge became the site of Saskatoon's only shipping disaster, when a steamboat called the SS City of Medicine Hat crashed into one of the bridge's piers and sank; all aboard managed to make it to safety. This accident marked the end of steamboat traffic on the river. An anchor presumed to be the SS City of Medicine Hat's was located in August 2006 by divers training just downstream, near the Broadway Bridge. This discovery led to a full-scale, five-day underwater excavation, which was conducted from September 8 to 12, 2008. A number of artifacts were uncovered from the water. A documentary film, titled "The Last Steamship: The Search for the SS City of Medicine Hat" was created in 2010 about the wreck and the search. More artifacts were unearthed in 2012 underneath Rotary Park, where the river used to run until it was covered by landfill to create the park in the 1960s.

Two roadways cut out of the riverbank are often associated with the Traffic Bridge. Short Hill referred to the steep rise up the east bank from the foot of the bridge along Victoria Avenue. The grade was too steep for most wagon teams, as well as the streetcars that began operation in 1913. Long Hill referred to the more gradual slope up the east riverbank from the foot of the bridge to the end of 12th Street, around where the end of the Broadway Bridge is today. This road followed the old ferry road up the bank along what is now Saskatchewan Crescent. Even the Long Hill was difficult for streetcars; in March 1922, a streetcar derailed when it slid off ice-covered tracks while attempting to turn onto the bridge.

The 2 metre-wide pedestrian walkway was added on the upstream side of the bridge in 1908. In 1961, the southern end of the bridge was raised to reduce the slope on the Short Hill and to improve traffic flow, allowing Saskatchewan Crescent to pass underneath the bridge. The bridge carried approximately 10,000 vehicles per day.

The bridge was repainted in 1979, albeit as little or no surface preparation was done the work was of dubious structural benefit. Beginning in the 1980s, the bridge started to show its age and needed to be closed periodically for refurbishment. Some adjustments were also made to widen the roadway, as many modern motorists were experiencing difficulty crossing the bridge. It was also closed for extended periods of time in the early 1990s when City of Saskatoon work crews damaged the bridge twice by driving over the bridge with vehicles too heavy or too large for the bridge specifications.

Closures

Temporary (2005–2006)

On September 6, 2005, the City of Saskatoon closed the bridge for inspection, in preparation for planned upgrades to the roadway (including the installation of the city's first roundabout (since the removal of the "traffic circle" on 8th Street a decade earlier) just off the north end of the bridge) in anticipation of an adjacent riverfront development (River Landing). On November 2, the bridge was closed indefinitely to vehicular traffic upon completion of the inspection, due to corrosion and other factors. The bridge was re-opened on September 8, 2006, following repairs that cost $500,000. The bridge remained open to pedestrian and bicycle traffic for most of this period. Replacing the bridge instead of repairing it would have cost between $24 and $45 million.

Without major repairs, engineers had given the bridge a 20 year life expectancy (either as a vehicle or a pedestrian crossing). The job of sandblasting the bridge to bare metal and re-painting it was made very expensive by the need to keep all sandblasting debris out of the river as the existing paint is lead-based.

The bridge's arches were equipped with several series of decorative LED lights in the summer of 2007. They included a programmable controller that made the lights change colour and move in different patterns. However, the lights proved controversial; they cost the city $462,000, which was almost twice the city's original estimate. They also broke down frequently, fueling further complaints from the public about their high price tag.

Permanent (2010)

On August 24, 2010, the City of Saskatoon closed the bridge to vehicles, bicycles and pedestrians following a preliminary inspection which could not conclude that the bridge was safe.

"When the preliminary inspection results came back this afternoon, the inspectors were not able to certify that the lower steel structural members inspected so far were safe," explained Infrastructure Services General Manager Mike Gutek. "We knew there was corrosion under there, but based on the limits and the extent of the deterioration, and in the interest of public safety, we are closing the bridge indefinitely."

According to Mayor Don Atchison on August 25, 2010, "The bridge is going to collapse. It's imminent that is going to collapse," further comparing it to the I-35W Mississippi River bridge collapse of 2007. The bridge's closure has led to traffic tie-ups leading into the downtown, which are feared to be long-term if the bridge is not repaired or replaced. One can assume, however, that since the completion of the Circle Drive South Bridge (which redirected a large percentage of traffic that formerly ran through downtown) that perhaps the traffic conditions will improve regardless if this bridge is restored or not. A 2010 poll conducted by Insightrix Research showed that the public was split over to repair or replace the bridge.

Replacement

Proposals

Partially demolished bridge in 2016

The city commissioned Stantec Consulting to consider options for the future of the Traffic Bridge. The report came up with a number of recommendations, ranging from rehabilitating the existing bridge to replacing it with a new structure. City council voted to eliminate any options that removed vehicle traffic from the bridge. After a series of public meetings and online surveys, the city administration recommended that the bridge be demolished and replaced with a modern steel truss bridge of similar design. On December 6, 2010, city council voted 8–3 to proceed. Although the final design, funding and timeline for construction for the new bridge are yet to be determined, it will be wider and possibly shorter than the existing structure.Template:Citation broken Proposals to salvage sections of the original bridge and its LED lights were scrapped due to cost, as decided by an executive committee in May 2011. Graham Commuter Partners was selected as the contractor, and illustrations of the new bridge were released in October 2015. The new bridge will have four spans instead of the original's five, built on the existing piers which will be reinforced.

Funding for the replacement of the Traffic Bridge was announced in 2014. In 2015, the city's administration said it could save money on the project if restrictions on the design were relaxed.

Deconstruction

Demolition of the bridge first began on May 28, 2012. The pedestrian access ramp on the south side of the bridge was removed first to enable load testing on the piers. Work began to tear down the first span on the east bank of the river on October 12, 2012. By October 18th, the first span had been severed from the rest of the bridge. On January 10, 2016, two spans of the bridge were imploded. The northernmost span was removed by explosives on February 7.
