5.05 Pathways, Crosswalks, and Ramps
It is preferable to use existing pathways, crosswalks, and ramps. Crosswalks and ramps should be located to allow pedestrians to cross during construction activities.
Crosswalks that are temporarily closed, should be removed or blocked. The use of temporary surfaces is acceptable for temporary pathways and should be ADA compliant or at a minimum provide an equivalent existing level of accessibility. Design, construction, and maintenance guidelines for pathways, crosswalks and ramps are provided in the following tables:
Table 5-5: Pathways, Crosswalks, and Ramps Guidelines: Design
- Pathways should be clear and flat.
|
- Detectible warning surfaces should be used at the ends off crosswalks on ramps.
|
- The pathway grade should not exceed 5% without incorporation of level landings.
|
- Temporary level turning spaces should be provided at ramps (minimum 4 × 4 feet, preferred 5 × 5 feet.)
|
- Cross slope perpendicular to traffic should be no more than 2%.
|
- Pathways must be at least 4 feet wide with 5 feet width preferred.
|
- Passing spaces must be provided at 200 feet intervals if the pathway is less than 5 feet wide.
|
- Passing spaces must be at least 5 × 5 feet.
|
- The maximum allowable rate of change of grade is 12.5%. The rate of change is determined by measuring the grade difference and the distance over which it occurs.
|
- A level turning space is required at both ends of a temporary curb ramp.
|
Table 5-6: Pathways, Crosswalks, and Ramps Guidelines: Construction
- Joints should be closed and flush.
|
- Vertical discontinuities along pedestrian routes should be less than ¼ inch.
|
- All surfaces should be firm and slip resistant.
|
Table 5-7: Pathways, Crosswalks, and Ramps Guidelines: Maintenance
- Clear pedestrian facility of debris, trash, mud, snow, ice, and standing water.
|
- It is preferable that drainage runs perpendicular to the pathway.
