WALLA WALLA –Three new buses funded by federal stimulus dollars for the Grape Line have arrived and soon will begin carrying passengers between Walla Walla and Pasco. The new Grape Line buses are the latest fruits from $1.9 million in federal American Recovery and Reinvestment Act (ARRA) grants for the Travel Washington Intercity Bus Program. Indiana-based bus maker Turtle Top Inc. manufactured the vehicles, each of which will carry up to 20 passengers.
