Poorly maintained facilities become unusable and a legal liability, as cyclists and pedestrians who continue to use them may risk equipment damage and injury. Others will choose not to use the facilities at all. Small rocks, branches and other debris can deflect a wheel, minor ridges in the pavement can cause spills, and pot-holes can cause wheel rims to bend. Wet leaves are slippery and can cause cyclists to fall. Gravel blown off the travel lane by traffic accumulates in the area where bicyclists ride.
Broken glass can easily puncture bicycle tires.
While walking, a person typically looks ahead and around, without noticing cracks and bumps in the sidewalk. A smooth, level surface is critical for disabled, young and elderly pedestrians. When street snow removal is stored on the sidewalk, conditions are degraded for pedestrians, especially where there is no buffer. A regularly scheduled inspection and maintenance program helps ensure that travelway litter is regularly picked up or swept. A smooth surface, free of cracks, potholes, bumps and other physical problems should be provided and maintained.
