Corduroy road

A Corduroy road or log road is a type of road made by placing sand-covered logs perpendicular to the direction of the road over a low or swampy area. The result is an improvement over impassable mud or dirt roads, yet is a bumpy ride in the best of conditions and a hazard to horses due to loose logs that can roll and shift. This type of road was already constructed in Roman times. Compare the puncheon or plank road, which uses hewn boards instead of logs, resulting in a smoother and safer surface.

Corduroy roads can also be built as a foundation for other surfacing. If the logs are buried in wet, acidic, anaerobic soils such as peat they decay very slowly. A few corduroy road foundations that date back to the early 20th century still exist in the United States. One example is the Alaska Highway between Burwash Landing and Koidern, Yukon, which was rebuilt in 1943, less than a year after the original route was graded on thin soil and vegetation over permafrost, by using corduroy, then building gravel road over top. During the 1980s, the gravel was itself covered with a chip-seal. During the late 1990s, this corduroy-underlain road began to be replaced with modern road construction, including rerouting of the entire highway.
