Cobblestone section 14 of the cycling classic Paris-Roubaix from Tilloy-lez-Marchiennes to Sars-et-Rosières with a length of 2,400m.
First used in 1980 but only for the first 1,400m. Used over its entire length from 1982. An L-shaped section of the D158b with two 90-degree right hand turns and one 90-degree to the left. Starts at 18m and finishes at 19m. Cobbles are in good condition and regularly maintained. Sometimes muddy because of use by tractors.
