The possibility is explored that the dust lanes frequently observed along the spiral arms of spiral galaxies are, at least in part, a result of shock compression of the gas caused by radiation pressure, due to hot, young stars, independent of any underlying gravitational density wave. The interstellar medium is treated as a compressible, supersonic, inviscid, isothermal, fluid dynamic system subject to a 1/r radiation force from a line source of luminosity representing the luminous spiral arm. The gas is confined by the gravitational force normal to the disk (the z-direction) and is assumed to have a free-stream normal velocity relative to the radiation source of Mach 1.2 for an isothermal sound speed of 10 km 1/s.
