Bridge Closing

The Mercer County Engineer, Jim Wiechart, is planning to close Cassella-Montezuma Road between Olding Road and Ashman Road/SR 119 in Marion Township for a bridge replacement.  This road will be closed tentatively on June 1, 2020 and is scheduled to reopen in approximately 6-8 weeks, depending on the weather conditions.

Spring planting & open ditch maintenance

The Mercer County Commissioners and the Mercer County Engineer would like to remind those who plant and till the fields around the county this spring to remember to avoid planting in the roadway right-of-way.  The Engineer and the Commissioner’s Office have maps that identify the varied widths of the road right-of-way throughout the county.  More specifically, sight problems limiting the ability of the traveling public to see, can be particularly hazardous.

Also, a reminder to those along county-maintained open ditches.  By law there is a maintenance easement for access adjacent to the tops of banks of the open ditches.  We encourage the use of filter strips to eliminate sedimentation and soil erosion adjacent to the open ditches.  Keep in mind that our maintenance crews use the easement for access for the maintenance operations we perform (the spraying of weeds and brush is the most significant maintenance operation).

Should you have any questions related to these requirements, please feel free to call the Commissioners’ Office at 419-586-3178 or the Engineer’s Office at 419-586-7759.

Road Closures (early-mid April)

The Mercer County Engineer, Jim Wiechart, is issuing a reminder to all drivers, that during the construction season and also at other times throughout the year, there are various temporary road closures in the county to allow our crews to do the repair/maintenance work required to keep our roads in good driving condition.  These roads may be closed intermittently on our normal work days (Monday thru Thursday 7:30 am-4:00 pm) as conditions and work requirements fashion.

The only reason a driver should bypass a “Road Closed” sign is to access a local address in the “closed” road area.  Through travel should detour away from the closure.

If local access is necessary and you must access the “closed” road, please use caution and drive slow to keep yourself and our workers safe.

Any additional questions contact the Mercer County Engineer’s Office at 419-586-7759.


 Mercer County Engineer, Jim Wiechart is announcing that over the upcoming construction season that engineer inspection and maintenance personnel will be on-site on many of the 111 miles of Mercer County maintained open drainage ditches and 62 miles of tile throughout Mercer County.

Easements exist along specific drainage infrastructure attributes that allow the necessary evaluation and maintenance of these important drainage elements.  Such things as ditch inspection, spraying for noxious weeds and erosion repairs will occur throughout the year.  “Many people may think that a ditch or tile is solely on private property, but all of Mercer County’s ditch and tile maintenance infrastructure attributes have a maintenance easement on and around the drainage feature.  A fraction of the open ditches and tile in the unincorporated areas are on county maintenance.”  Wiechart stated.
