Paper reviews effects of permafrost and muskeg foundation materials on bridges, and culverts after 16 yr of service; role of wild streams and "gravel fans"; in winter maintenance of culverts, steam pipe equipment is used, but in more severe cases, drum of oil set up at one end of culvert with continuously burning flame keeps structure de-iced.
