This ramp is designed to provide mobility access from an upper parking lot to a lower level entryway without a direct wheelchair unloading zone. Access to the main part of the building is provided by an elevator. While lengthy it is still narrow and barely within ADA standards for a commercial ramp. The wheelchair user in the above picture is using smaller junior sized power wheelchair. Larger adults or those with equipment attached will have difficulty accessing this ramp.
This ramp is shaded for a good portion of the day and as such is subject to frequent icing making the surface treacherous at times.
By slightly widening the sidewalk from the upper level parking lot wheelchair users would be able to easily transverse the slope to the lower entry. The sidewalk is in full sun most of the day which decreases incidents of icing in all but the most adverse of weather conditions.
We usually prefer to take the sidewalk.
