Vedder Bridge Replacement Project

Project Update, June 19, 2017

Another significant milestone in the project takes place this week as casting of the concrete bridge deck and multi-use walkways are poured during night time operations.

To yield a top quality product bridge decks cast in the summer need to be cast during the coolest part of the day, which is normally between 12am and 9am. These works will have minimal impact on traffic as it is taking place off-line from Vedder Rd and Vedder Mtn Rd traffic flow.

BC Hydro and Telus crews continue to complete works this month to convert their existing overhead infrastructure to underground across the new bridge.

Concrete curb and sidewalk pours are scheduled in the coming weeks along Vedder Mtn Rd and the new roundabout north of the bridge. A temporary wall is currently being constructed along the west side of Vedder Road to allow traffic flow to continue uninterrupted as roundabout construction is completed.

Project Update, April 13, 2017

Hundreds from the community came out on April 11, 2017 to witness the historic event of the new bridge being launched across the River. The move took more than 7 hours to reach to south pier and has been summarized in the video produced by InMist Media House below. The bridge launch continues through today to the south abutment. Bridge and roundabout construction will continue off-line of traffic into the summer with traffic being transferred to the new bridge in August. Single-lane closures along Vedder Mtn Road will continue into May during curb and sidewalk construction.

Project Update, April 4, 2017

Bridge launch over the Vedder River is scheduled for April 11th. A King Post Support System will be used in conjunction hydraulic jacks and skid shoes to propel the bridge across the River without any in-stream temporary supports. Although the bridge is 80 meters in length, the critical part of the launch is the first 60 meters when the bridge is cantilevered over the river, until the south end of the bridge touches down on the pier. It is anticipated that the first 60 meters of travel will be completed in one day. (April 11th) The remaining 20 meters of travel requires a series of detailed and coordinated steps and is anticipated to take two to three days to complete. (for further details on the bridge launch see attached below)

Quick Facts

  • This is the first arch bridge in the world (that the Design-Build Team is aware of) that has been launched with a king post support system.
  • The total weight of the bridge, suspended pipes, launch girder, and counter weight is approximately 420 tonne (926,000 lbs)
  • The total weight of the counter weight is approximately 148 tonne (326,300 lbs)
  • The bridge was fabricated in Delta, BC, at Supreme Steel’s Canron facility.
  • The launch cable is a spiral strand cable with a minimum breaking strength of 4,070 kN (415 tonne –force, 915 kip) .
  • One launch cable weighs approximately 2,000 kg (4,400 lbs)
  • The precast concrete counterweight panels, will form part of the bridge deck after the bridge is in place.
  • The bridge system has been designed to minimize the amount of work needed to be completed over water. Completing work over land is far safer, more productive and cost effective.
  • The suspended utilities (sanitary, water, gas, BC Hydro, and Telus) have all been preinstalled under the bridge.

Underground utilities and road works requiring single-lane closures will continue thru April that will impact traffic flow.  These necessary works are being scheduled prior to the higher traffic volumes coming later this Spring.  The contractor is working to minimize delays but intermittent traffic impacts can be expected throughout the day.

Project Update, February 24, 2017

Bridge foundation and steel fabrication works will continue into April on the Vedder Bridge Replacement Project off-line of traffic flow.

Underground utilities and road works requiring single-lane closures have begun and will continue thru March that will impact traffic flow.

These necessary works are being scheduled prior to the higher traffic volumes coming later this Spring.

The contractor is working to minimize delays during the morning commute but intermittent traffic impacts can be expected throughout the day.

From February 27th – March 7th, work along Chilliwack Lake Road will require weekday closures of the Rotary Trail immediately upstream of the bridge.

Project Update, October 11, 2016

The Rotary Trail Parking Lot is now closed, as part of the Vedder Bridge Replacement Project.

Trail users are encouraged to use the recently expanded Vedder Park parking lot accessible off Petawawa Road.

During the first 10 months of Bridge construction most works will be off-line of traffic and should have minimal impact on traffic flow.

Project Update, April 20, 2016

On April 19, 2016, Council accepted the proposal for the Vedder Bridge Replacement Design-Build Project from the lead proponent, Emil Anderson Construction Inc., in the amount of $11,331,052 (plus applicable taxes).

Out of the three proponents that advanced to RFP Stage 2, Emil Anderson Construction Inc. earned the highest technical points and submitted the lowest cost proposal for both Option 1 (Steel Girder) and Option 2 (Steel Arch) bridge designs. Thanks to the lower bridge price, Council was able to select the more visually appealing steel arch option and still remain within budget expectations. The reduction in construction costs also allows for provisional items, such as the Rotary Trail Connection and increased costs for necessary BC Hydro and Telus overhead and underground utility relocations.

Based on the proposal, construction is anticipated to start in September 2016, with substantial completion of the project by October 2017. The document highlighted that the first 10 months of construction will be completed parallel to Vedder Road allowing traffic to continue as usual. In addition, Emil Anderson Construction Inc. provided plans showing how the proposed works can be staged to minimize disruptions to traffic.

Project updates will be posted throughout the upgrade process.
