Calling freight movement “vitally important” to Oklahoma’s and the nation’s economy, the Oklahoma Department of Transportation said it received federal approval for its five-year Freight Transportation Plan, to accommodate expected increases in the 800 million tons of freight valued at $1.3 billion that move through the state via rail, truck and waterway each year. The approved plan details freight trends and traffic forecasts to identify significant freight transportation projects needed in the state that will help develop partnerships and target economic growth across all modes of transportation. The state said about 58% of all freight in Oklahoma is transported by truck and 41% by rail.
