Benefits of speed humps

Speed humps are a form of traffic calming used to reduce the impacts of traffic on neighbourhoods and public facilities such as parks, school areas, and community centres. 

A speed hump is a gradual rise and fall of the pavement surface along the roadway extending across the pavement width. Generally, speed humps used on residential streets are four metres long with a maximum height of 80 mm. Speed humps differ from speed bumps which are seen in many private parking lots. Speed bumps cause most vehicles to slow down to almost a stop to go over it. Speed humps, on the other hand are designed so most vehicles can go over them at 30 kmh without causing driver discomfort.

During construction, there may be dust and noise in the area. The City makes every effort to reduce the impact to nearby residents and business owners. Thank you for your patience as we work to improve the roads and infrastructure in your neighbourhood. The City of Greater Sudbury and its contractors are committed to public safety and will monitor the ongoing progress of construction.
