The La Crosse County Highway Department says crews will begin construction on County Road OA on May 20, causing road closures.

The road from County Road O to County Road FO will only be open to local traffic during construction, according to the highway department.  

There will be a detour on Country Road M until the road reopens.  Construction is scheduled to finish in October.

Construction of an access road will also force CTH OA south of County Road FO to be closed starting Tuesday, May 28.  The road will reopen at a later date.
