Over the years a total of 29 covered bridges were built in the county. Some were built for turnpikes, one for the railrod, one by a private enterprise, and some to replace original ones that were destroyed in a storm in May of 1886.

After the 1886 storm, Evret Sherman, a covered bridge builder originally from Vermont, moved from Delaware County to Eaton. Sherman built covered bridges of the Childs truss and the kingpost truss type.

Today, seven covered bridges remain in the county.

• The Roberts - the oldest covered bridge in the state of Ohio, the second oldest in the US, and one of six remaining double-barreled covered bridges in the US. This bridge was moved from its original location to a park in Eaton.
• The Brubaker - this bridge was renovated in 2006
• The Dixon Branch - this Childs truss type was moved to the park in Lewisburg and shortened by 10 feet.
• The Harshman - this covered bridge is 109 feet long and was built by Sherman in 1894.
• The Geeting - this bridge was also built by Sherman in 1894 and is 100 feet long
• The Christman - another built by Sherman, but in 1895, and is 100 feet long.
• The Warnke - this bridge was built in 1896 to replace an iron brideg. It was probably the last covered bridge built by Sherman, who passed away shortly after its completion.

Start your covered bridge tour at the Preble County Historical Society. If we are not open, we have a map board to the left of our garage that has covered bridge maps and driving instructions. Just remember that the Brubaker bridge is closed.
