During the winter of 1998-1999, FERIC and Quebec's Ministère des Ressources naturelles evaluated three methods of installing temporary stream crossings on winter roads. This report provides a detailed evaluation of the following three structures: a culvert stabilized with snow, a culvert stabilized with tree stems, and a crossing made solely from compacted snow. The study showed that these temporary structures could eliminate sedimentation of the streams and were generally less expensive than permanent structures.
