Looking out at Wolf Creek, winding its way through the woods off Township Road 9, west of State Route 53 in Ballville Township, is the only covered bridge left in Sandusky County and one of the few in Northwest Ohio.   The six mile trip to the covered bridge is a look back into the past by about 130 years.
A family by the name of Mull owned a saw mill in the area and needed a bridge for customers to reach their mill.   Amos Mull consulted with John Diehl, Chairman of the Ohio Covered Bridge Committee and the Sandusky County Commissioners for the erection of a bridge over Wolf Creek near Mulls Mill in Ballville Township.  The commissioners appropriated 75.00 for the construction of the bridge.  Mull furnished the wood from his mill and most of the structure still consists of the original lumber.   The bridge was named for Amos Mull, who lived in the house at the East end of the bridge.  The house still stands today.
The Mull Covered Bridge was open to traffic until August 2, 1962.  A new bridge constructed on Township Road 9 resulted in no further need of the Mull Covered Bridge.  The County Commissioners bowed to a request from the Sandusky County Historical Society to maintain the Mull Covered Bridge as a historical sight.  The Commissioners then adopted a resolution authorizing the expending of funds for the preservation and maintenance as a memorial for historical purposes.
The Mull Covered Bridge is maintained by the Sandusky County Park District.
