Location

The William R. Bennett Bridge is a pontoon bridge in the Okanagan Valley of British Columbia, Canada. Completed on May 25, 2008, the bridge replaced the older Okanagan Lake Bridge built in 1958 to link Downtown Kelowna to West Kelowna across Okanagan Lake as part of Highway 97.

On April 21, 2005, Premier Gordon Campbell officially renamed the bridge, then the Okanagan Lake Bridge, the William R. Bennett Bridge in honour of former premier Bill Bennett, a native of Kelowna.

Construction budget

The first press release from the British Columbia Ministry of Transportation to include budget information was in 2003. At that time, the project was estimated to cost CA$100 million for the bridge and another $20 million for the two interchange upgrades on the west side of the lake.[1]

By June 29, 2005, the cost of the bridge had increased from the previous estimate of $100 million to $144 million "due to dramatic increases in the cost of construction materials and labour", which included significant increases in the cost of concrete, steel, and fuel. Over the next 30 years, the province of British Columbia expected to pay SNC-Lavalin a total of $179 million "to design, build, finance, operate, maintain and rehabilitate the bridge".[2]
