Sheridan Stop: This seemingly small hole is located in the 900 block of West Sheridan Road. When you look down, you can clearly see that water has eroded the ground underneath the sidewalk, leaving the underside hollow and vulnerable to collapse.

This sidewalk sees a lot of use from residents and other commuters.

Don’t like what you see? Call 311, Contact Ald. James Cappelman (46th) or the Chicago Department of Transportation.
