Curb Extensions

Curb extensions are also known as bump-outs. They reduce the width of the roadway by extending the boulevard and/or sidewalk into what is currently either a travel lane or a parking lane. For maximum effectiveness, the approach lane width is typically reduced to 3.0 metres on local roads.

For designated cycling routes, the lane width should be increased to provide additional room for people cycling. On-street parking will typically be lost opposite a curb extension.

Curb extensions are often used at intersections to reduce crossing width.
