A section of the Arkansas Highway 187 that crosses the dam will be closed for three weeks, according to officials.
The work on the Beaver Dam in Carrol County will restart on April 30.
The closure will be organized with emergency services and law enforcement agencies.
Officials say people who travel in the area need to plan an alternate route and allow extra time to reach their destinations.
An alternate route could be Highway 62.
