Expanding the city’s cycling network has cost 30 per cent more than what was originally forecast just over three years ago, transportation planners say.
“Site-specific conditions such as contaminated soils, poor slope stability and utility conflicts are difficult to anticipate during master planning and have resulted in increased project costs,” the planners told council in a report published this week.
New accessibility standards also require upgraded traffic signals, another unanticipated cost that will now be considered in new cycling projects.
