Motorists who take Iowa 21 in Keokuk County are advised of an upcoming road construction project beginning on Monday, May 8.

The intersection of Iowa 21 and Iowa 92 north of Delta will be closed while crews make improvements and reconstruct the Iowa 92 roadway. During this construction, drivers on Iowa 21 will follow a marked detour route using Iowa 22, Iowa 149, and Iowa 92.

Access to properties and the cemetery will be maintained, and intermittent lane closures, flaggers, and pilot cars will be used to direct traffic through the work zone. The project is anticipated to continue until mid-June.

The Iowa Department of Transportation reminds motorists to drive with caution in these areas, as well as all work zones, obeying the posted speed limit and being aware of construction crews. For the latest traveler information, visit 511ia.org or call 511.
