Taxiway Edge Markings. Used to define the edge of the taxiway when the taxiway edge does not correspond with the edge of the pavement. Continuous Markings consist of a continuous double yellow line, with each line being at least 15 centimetres (6 in) in width spaced 15 centimetres (6 in) apart and define the taxiway edge from the shoulder or some other abutting paved surface not intended for use by aircraft. Dashed Markings. define the edge of a taxiway on a paved surface where the adjoining pavement to the taxiway edge is intended for use by aircraft, e.g., an apron. Dashed taxiway edge markings consist of a broken double yellow line, with each line being at least 15 centimetres (6 in) in width, spaced 15 centimetres (6 in) apart (edge to edge). These lines are 15 feet (4.5 m) in length with 25 foot (7.5 m) gaps.
