Imagine trying to do that in a wheelchair? It does not look easy and can be tiring for one arm.

This is what we call the crossfall. It’s the slope or angle of a footpath from one side to the other (the width).

Often times, crossfalls are created for the purpose of enabling rainwater or other liquids to flow naturally to the drains and prevent puddles and flooding. However, this means difficulty for wheelchair users.

Common intentional crossfalls are often not very steep that someone walking will not really notice. But for wheelchair users, even the slightest angle is difficult for them to wheel and can be exhausting.

To the natural eye, the crossfall in this image is barely noticeable. But to a wheelchair user, it creates difficulty.

Footpath Crossfall is subcategorised by the measurement of the steepest angle that cannot be avoided:

• 0.00 - 1.4 degrees

• 1.5 - 2.9 degrees

• 3.0 - 4.4 degrees

• 4.5 - 5.9 degrees

• 6.0 degrees +
