Grands Boulevards
France
Grands Boulevards (French pronunciation: [ bulva]), formerly named Rue Montmartre (1931–1998), is a station on Lines 8 and 9 of the Paris Métro. In 2019, it was the 44th busiest station of the Métro network, with 6,807,424 yearly users.
The section of both lines from just east of Richelieu–Drouot to west of République was built under the Grand Boulevards, partly on the border between the 2nd and 9th arrondissements, that replaced the Louis XIII wall and is in soft ground, which was once the course of the Seine. The lines are built on two levels, with Line 8 on the higher level and Line 9 in the lower level. The platforms are at the sides and the box containing the lines and supporting the road above is strengthened by a central wall between the tracks.
