We report simulations of the gas flow in the gravitational potential of the COBE NIR bulge and disk. These models lead to four--armed spiral structure between corotation of the bar and the Sun, in agreement with the observed spiral arm tangents. The 3-kpc-arm is identified with one of the arms emanating from the ends of the bar.
