Roadway Design Manual




Notes:
  1. Computed using Superelevation Distribution Method 2.
  2. Superelevation may be optional on low-speed urban streets.
  3. Negative superelevation values beyond -2.0% should be used for low type surfaces such as gravel, crushed stone, and earth. However, areas with intense rainfall may use normal cross slopes on high type surfaces of -2.5%.
