A minimum vertical clearance of 2.3 m shall be provided for the covered walkway. A minimum clear width of 1.1m is required for hoarding/covered walkways sited on a carriageway. As regards hoarding/covered walkways on a footpath, the clear width should be related to the existing pavement as set out in Table 3.1. The required clear width must not be obstructed in any manner e.g. by traffic sign, temporary supports, scaffoldings or the like. The width of the catch platform shall not be less than 2 m when it abuts a street and may be reduced by the amount of set back of the building. Separation distance between the walkway cover and the catch platform shall be individually determined according to the design need, e.g. maintenance. A minimum clearance of 5.5 m shall be maintained for the catch platform within a minimum distance of 500mm from edge of a carriageway unless otherwise agreed by the Highways Department. 5.5m clear headroom over gantry shall be maintained as far as practicable.
