(AP) – Missouri transportation officials are taking a closer look at how freight can be moved more efficiently across the state by trucks, barges, planes and trains.

The Department of Transportation plans a series of forums across the state in the next two weeks to help develop a “Missouri Freight Plan.”

The plan will identify the freight projects that could be most helpful to the state if additional money becomes available. A draft is to be done by June and a final report by September.

That would come in advance of a potential November ballot measure asking Missourians to impose a 1-cent sales tax to raise money for roads, bridges and other modes of transportation.

The Department of Transportation says Missouri exported about $14 billion of freight in 2012.
