The value of public infrastructure in Saskatchewan amounted to $9.0 billion in 2007. Saskatchewan had the third oldest infrastructure in the country in 2007, exceeded only by Nova Scotia and Manitoba. This was mainly attributable to the fact that these three provinces, along with Newfoundland and Labrador, are among those having the oldest stock of highways and roads in the country.
However, Saskatchewan has seen major reduction in average age in most of its public assets since the beginning of the millennium. The average age of all assets combined was reduced from a peak age of 19.4 years at the beginning of the millennium to 17.6 years in 2007. Like Manitoba, the recent reduction was driven mainly by new investments and the discarding of older investments in the road asset.
