The city’s transportation committee has approved the original design for the 102nd Avenue bridge over Groat Road even though it will cost $11.5 million more than planned.
The cost of the bridge was $20.7 million when estimates were first done in 2011. Councillors learned last month that the price has increased to $32.2 million.
Administration was asked whether a narrower bridge could be built to save money, but Coun. Amarjeet Sohi said it had the potential to create legal problems.
"It will not meet the standards," he said.
"The lanes will be narrower so you have potential liabilities if accidents happen or collision happens or if you don't have enough room between the vehicles and the cyclists or between the vehicles, so building a narrow bridge is not an option."
Construction costs have increased by 2 per cent each month since the 2011 estimate, Sohi said.
The city will cover the cost overrun by postponing construction on Jasper Avenue between 109th and 116th Streets.
The bridge will replace the existing structure which was built in 1910 and has reached the end of its service life, according to a city report.
Construction is scheduled to start in 2014 with completion by fall of 2015.
