Road 304 and Yoncalla Creek Road are located in the timberlands of the Grand Ronde Indian Reservation. Road 304 takes off from Yoncalla Creek Road and immediately crosses Yoncalla Creek. The Yoncalla Creek crossing consists of a corrugated metal pipe (CMP) culvert that stands approximately 12 feet wide by 7 1/2 feet tall in a crushed arch-pipe flat bottom configuration.
