South Dakota transportation officials are warning motorists about driving around barricades on closed highway sections.
Officials say motorists have been moving barricades and driving through a construction zone on Highway 34 east of Howes. A semitrailer got stuck in the mud over the weekend after heavy rain moved through the area.
Officials say people who drive in work zones risk safety and also can damage roads. Tampering with traffic control devices and driving around barricades also are misdemeanor offenses.
Highway 34 is closed for a 2 1/2 mile stretch so workers can repair erosion on dams for Howes Lake and Lake Buffalo. Traffic is being detoured. The Highway Patrol is monitoring the area.
