Green scene: Senior Highways Engineer Chan Che-keung shows how plants will be added to the sides of a new footbridge on Lung Cheung Road. Examples of vertical greening can be seen on the Kong Sham Western Highway noise barriers and under the Canal Road Flyover.

To meet growing demand for a greener cityscape the Highways Department is putting extra effort into its bridge design and construction to include more environmental elements.

Bridges & Structures Division Senior Engineer Chan Che-keung recently told news.gov.hk the department is studying the viability of planting grass on top of footbridges, and considering expanding the scale of vertical greening, such as under bridges and over noise enclosures.
