Drivers can now check out where speed limits will change in their neighbourhood after the City of Calgary released final drafts of maps this week.
The roads in yellow will have a new 40 kilometres per hour unposted default speed limit starting May 31.
The red roads will have a 50 km/h posted speed limit.
The changes will happen on residential roads and some collector roads.
Residential roads, usually those without a centre line, will drop to 40 km/h.
The same goes for some of the collector roads that weave through neighbourhoods, depending on a number of factors, such as the amount of green space or if there’s a bus or snow route.
City data shows 9,100 car crashes happen in Calgary neighbourhoods every year, with an average of 550 resulting in injury or death.
City council hopes the changes will stop about 450 collisions and 29 deaths annually.
