Median Lighting Design Examples
The following illustrations show typical median lighting designs for various controlled access roadway sections.
Example 1 — Unprotected Median:
Figure 6‑5 shows a typical median lighting design for a controlled access roadway having an unprotected median 30 feet or greater in width. Here breakaway poles should be used.
Figure 6-5. Median lighting with breakaway poles.
Where median width exceeds 60 feet, it may be necessary to treat each main lane as a separate roadway, using two rows of poles in the median or house side (see Figure 6-4 for illustration of house side lighting).
Example 2 — Concrete Median Barrier:
Figure 6‑6 shows a typical median lighting design for a controlled access roadway having a concrete median barrier. Median width in this situation is typically 20 feet.
Figure 6-6. Median lighting with concrete median barrier.
The following table shows the recommended lighting for concrete median barriers.
Number of Lanes | Luminaires | Mounting Height | Spacing |
|---|---|---|---|
2 or 3 each direction | 250W EQ LED | 40 feet | varies |
4 or 5 each direction | 400W EQ LED | 50 feet | varies |
