PIERRE, S.D.(KCCR)- Over 35-hundred South Dakotan have been killed on South Dakota roads over the last five years.  Highway Safety Engineer Dustin Witt with the South Dakota Department of Transportation says lane departures and curves accounted for most of those.

Witt says multiple focus areas can compound on each other as shown in the Department’s five year update of it’s Strategic Highway Safety Plan.

Witt says the department is spending money to reduce lane departure crashes.

Center line rubble strips are being incorporated into new highway projects to expand their use to reduce lane departures on state highways.
