Description
A ~32 km solar-canopy cycle highway runs down the median of a six-lane motorway between Daejeon and Sejong. Panels are mounted as a roof over the cycle lane — angled for optimal efficiency and air-cooled — rather than embedded in the riding surface. The motorway median supplies the land at no additional acquisition cost; the canopy structure simultaneously shelters cyclists from sun and rain. Precise generation figures were not captured in the sources reviewed and should be sourced from the operator before use in planning.

Lessons learned
- Mounting panels as a canopy rather than embedding them in the riding surface preserves conventional tilt and air-cooling, avoiding the efficiency and durability penalties of flat embedded designs such as SolaRoad.
- Stacking a second public benefit (sheltered cycle infrastructure) onto generation strengthens cost-justification for the canopy structure versus a standalone array on the same median land.
- Motorway medians are low-conflict siting resources: land access is already committed, no separate acquisition is needed, and conflict with adjacent landowners is minimal.
