the station, forcing the evacuation of the 300 passengers inside. Origin of the name Berri–UQAM is named for both Berri Street, so called since 1663, and for the Université du Québec à Montréal. The university has taken to using UQAM as its abbreviation, which it displays as UQÀM (with a grave accent over the A as its logo; the station retains the UQAM form). Until 1988, the station was named Berri-de-Montigny; rue de Montigny is the former name of boulevard de Maisonneuve in this area. Small stubs of de Montigny street still survive in Downtown Montreal between Saint Laurent Boulevard and Saint Urbain Street and in the Montréal-Est suburb. Station improvements In 2009, the station was made partially wheelchair-accessible, with two elevators connecting the Orange Line platforms to the mezzanine. From August 2010 to mid-2017, the station underwent $90 million of renovations that changed the appearance of the station and secured the tunnels and the roofs. Other work that was done included mechanical, structural, and architectural improvements. The first phase lasted from August 2010 to the summer of 2011 and included the removal of the gray tiles on all 3 platforms and station walls. Temporary walls were put up until the next phase. The second phase began in January 2012 and continued until June 2012. It included reinforcing walls; renovating mechanical, structural, and architectural components, and removing four red columns on the mezzanine level staircases. Once that was completed, the temporary walls and finishes were removed and replaced by new permanent architectural facings. In early 2013, the STM refurbished the station's main electrical conduits and therefore had to shut down several escalators. In the same year, the Berri and Place Dupuis entrance buildings have been renovated, with new structural slab, ceilings, light fixtures, floor coverings and granite stairs. From fall 2013 to fall 2014, part of the waterproofing membrane under Berri has been replaced. In 2015. the Yellow line area has been refurbished, with new wall finishes and floor coverings, as well as improved lighting. The tunnel ceiling and walkway over the tracks have been also revamped. In 2016, the Saint-Denis entrance building has been refurbished, and a few corridors to the Orange and Green line platforms have been rearranged. The staircase between the two levels has been refurbished. The Green line platforms are accessible as of November 2020. , construction to provide elevators to the Yellow Line is underway,
