The Carrefour de l'Arbre is one of three five-star cobbled sectors of Paris-Roubaix, together with Mons-en-Pévèle and the Trouée de Arenberg. The 2.1km stretch of pavé is located between Camphin-en-Pévèle and Gruson.
The Carrefour de l'Arbre sector has been used in Paris-Roubaix since 1980 and is typically the fourth to last cobbled stretch out of more than 50. It has frequently provided a launchpad for the race winner.
While not as demanding as the Arenberg forest, this sector is given a five-star rating because of the accumulated fatigue of the sections of pavé before it. In 2025, the section arrives after 50.4km of pavé and ends with 15km to the finish.
Mat Hayman, the 2016 Paris-Roubaix winner, said the section is brutal: "Part of me has thought that if I crashed or punctured, then at least I'd be able to lie down on the grass."

Carrefour de l'Arbre Strava segment
The first part of the sector starts from the Rue de Cysoing in Camphin-en-Pévèle and has a quick series of turns on a false flat with the cobbles becoming increasingly uneven. After a sharp left turn, the second part of 900 metres is straight and smoother, passing the Restaurant l'Arbre.
The Carrefour de l'Arbre is considered to be the last chance for a winning attack. In 2022, Dylan van Baarle attacked here to drop Matej Mohoric and Yves Lampaert and rode solo to victory. Other recent solo winning moves have come here from Fabian Cancellara in 2006 and Stuart O'Grady in 2007.
The sector can decide the winner and the loser, too. In 2009, Thor Hushovd crashed in one of the turns, allowing Tom Boonen to solo to the victory. In 2013, Stijn Vandenbergh and teammate Zdenek Stybar crashed into spectators on this section.
The Carrefour is invariably packed with fans, some of whom have behaved badly in the past. During the years of Tom Boonen's dominance, it attracted thousands of Belgians, many worse the wear from drink. Filippo Pozzato claimed to have been spat on, while the Saxo Bank team car had its wing mirrors vandelised. The mob left so much trash in their wake that the mayor of Camphin-en-Pévèle threatened not to let the race use the roads in 2009. In 2010, the race organisers beefed up security and banned the sale of alcohol to keep the crowds in check.
Upon creation of the women's Paris-Roubaix in 2021, the sector was included in that race as one of two five-star stretches of pavé.
