| Guideline | Cross Slope Design Guideline 1 |
| Title | Cross Slope Ranges |
| Text | Design of cross slopes should follow the methods and guidelines provided by the AASHTO “Green Book” and or the respective state DOT design manuals. Drainage design needs to address runoff from the canopy. Cross slopes will typically range from 1%-2% on tangent roadway sections and higher on curves. |
| Commentary | The drainage design must combine cross slopes with longitudinal grade to avoid any water ponding within the toll plaza. Canopy runoff should be directly piped into the drainage system. |
| Guideline | Cross Slope Design Guideline 2 |
| Title | Rollover Ranges |
| Text | Design of rollover of adjacent lanes should follow the methods and guidelines provided by the AASHTO “Green Book” and or the respective state DOT design manuals. Rollover should be limited to a combine grade differential of 4%. |
