Montrealis synonymous with "pothole," and this is especially obvious in the spring. As the snow melts and the streets slowly r-appear, the yearly ravages of winter become obvious.
If you feel like some areas are more pothole-prone than others, you would be right. Félix Lévesque, a data scientist who works in Montreal, has compiled data sourced from Montreal's open data portal to find out which areas and streets are most affected by potholes.
TL;DR Using open data from the city of Montreal, a data scientist has put together information about the most pothole-ridden areas and streets in the city.
The data Lévesque used is from the last two winters for which data is available: winter 2016/2017 and winter 2017/2018. In total, 215,858 potholes were repaired in 2016/2017, compared to 180,235 in 2017/2018.
The city rushes to fix its potholes in the winter and early spring so as to limit serious damage to cars and bikes. Most potholes are fixed in March and April.
The author points out humourously that the Vatican has a density of 2300 citizens/km².
Rivière-des-Prairies–Pointe-aux-Trembles, one of the city's largest boroughs, is in a league of its own, with 46,500 potholes repaired in two winters.
The streets with the most potholes include Boulevard Pie-IX (1392 potholes/km), rue Sherbrooke Est (767 potholes/km), and Notre-Dame Est (676 potholes/km). A heat map shows the extent of repairs on Sherbrooke:
Boulevard Pie-IX has been repaired so many times that, if we assume that reparations on the boulevard are spread evenly and that the average human walks about 0.78 m. per step, a human could walk down Pie-IX by only stepping in historically repaired potholes.
