 The U.S. Department of Transportation's Federal Transit Administration has announced that Rock Region Metro in Little Rock was one of 117 entities in 47 states, receiving part of $1.5 billion in federal grants. The Rock Region grant, the only one in Arkansas, is $3.1 million for up to five new buses. The funding will be used to buy low-emission buses to replace older diesel buses and a simulator to train staff in new technology.
