The prototype is for a 4' mini ramp with deck. Each section is 8' wide and has one transition. Four such sections, welded together, would make a 16' wide mini ramp with 10' flat-bottom. The prototype drawing could be modified to make a spine ramp or to add bowl corners. The prototype could also be modified to make a taller mini ramp or vert ramp.
A pram ramp with tactile paving that connects a sidewalk to a road. A curb cut , curb ramp, depressed curb, dropped kerb , pram ramp, or kerb ramp is a solid (usually concrete) ramp graded down from the top surface of a sidewalk to the surface of an adjoining street. It is designed primarily for pedestrian usage and commonly found in urban ...
The ramps on these were folding types giving a longer, 65 ft (20 m), crossing. [8] The Twin-ARK was used for the post-war Conqueror heavy tank. Ark Mk II had a wider, 4 ft (1.2 m) instead of the usual 2 ft (0.61 m), trackway on the left side so narrower vehicles could also use the ARK. These were conversions of the Ark Mark I in mid-1944.

Longer bridges can reduce the width of both shoulders to 4 feet (1.2 m). Existing bridges can remain part of the Interstate system if they have at least 12-foot-wide (3.7 m) lanes with 3.5-foot (1.1 m) shoulder on the left and a 10-foot (3.0 m) shoulder on the right, except that longer bridges can have 3.5 feet (1.1 m) shoulders on both sides.
The primary US guidance is found in A Policy on Geometric Design of Highways and Streets published by the American Association of State Highway and Transportation Officials (AASHTO).

Cross section of a road. 1. Gutter; 2. Shoulder; 3. Sub-base; 4. Base course; 5. Asphalt. Cross slope, cross fall or camber is a geometric feature of pavement surfaces: the transverse slope with respect to the horizon.
The vehicle deck measures 76 m (249 ft) by 7.4 m (24 ft) and is equipped with a cargo hatch that measured 30 m (98 ft) by 7 m (23 ft). Vehicles and personnel can disembark from a bow ramp that is 18 m (59 ft) long and 4.5 m (15 ft) wide. A stern ramp is also fitted that measures 5 m (16 ft) in length and 4 m (13 ft) in width.
