Weather permitting, Clay County Highway Department will begin oiling and seal coat of some County Highways on Monday, August 7th and continue through Friday, August 11th.   Motorists are asked to use extreme caution when traveling through the work zones, or avoid them if possible.  Daytime lane closures can be expected while the work is in progress.  The roads affected will be CH 9 (Mahogany Rd), CH 4 (Old Ingraham  Rd), CH 10 (Indian Ridge Rd), CH 6 (Xenia Iola Rd from Xenia to Kinmundy Rd), CH 16 (Ingraham Ln from Ingraham to Richland Co. line) and CH 18 (Songer Township Ln from Beard Rd to CH 6).  Your patients and cooperation are appreciated as the Clay County Highway department works to improve your roads.

Boxwood Road between the intersection of Fir Lane and Geiger Lane is open to traffic.  Seeding will take place as weather allows.  Please use caution as the final construction is completed.  Thank you for your patience. 

Jasper Road from Metal Road to Venus Road will be closed until further notice due to traffic damaging the bridge deck.  This closure is due to a safety hazard and NO traffic is allowed to cross the remaining structure.  Construction will begin fall of 2017.  Moving, damaging or destroying warning signs is a criminal offense and jeopardizes the safety of others.  Thank you for your patience and understanding.

Township roads will begin receiving oil and rock soon.  Be alert for traffic control signs and flaggers.  Obey all instructions and drive carefully through construction zones.  Thank you for your patience and understanding.
