Hundreds of rusting streetlamps to be replaced by city
Calgary tripling number of repairs as poles age, risk falling over
Concerns about thousands of rusting streetlight poles are prompting the city to accelerate a program to replace them.
CorTen steel poles are rust-coloured and are designed to last up to 40 years. But, as they near the end of that time, some have started to rust out at their base and a few have actually fallen over.
There are 15,000 of them in Calgary, most installed between 30 and 40 years ago.
The city's general manager of transportation, Mac Logan, says that city council has approved plans to increase the number which are replaced annually from 500 poles to 1,500.
The older poles are being replaced with ones made of galvanized steel and are designed to last up to 60 years.
