Road transport faces many problems in difficult relief regions. In mountainous regions, roads are hard to build because of steep slopes, and they may be blocked by landslides, avalanches, or snow. In desert regions, loose sand and extreme heat make construction and maintenance difficult. In flood-prone regions, roads and even metalled roads become damaged or unmotorable during heavy rains and floods. Thus road transport is unreliable and costly in such areas.
