Highways and roads in Prince Edward Island accounted for half of the total public infrastructure stock in the province in 2007. This ratio was the lowest in the country - the national average was 59% - and can be explained by the unusually large weight of the Confederation Bridge in the total asset pie.
The provincial road network in Prince Edward Island has benefited from sustained investments from the mid-1980s until the early 2000s. The average age of this asset thus lessened from a high of 19.5 in 1984 to a low of 12.5 years in 2002. However, average age has since increased to 13.9 years in 2007.
Roads in Prince Edward Island reached 49% of their estimated useful life in 2007, compared with 53% for roads nationally. As a result, this province, along with Ontario, had the youngest road network among provinces.
