front of a Chinese elderly care facility. Despite demands to relocate the route to 102a Avenue, the city council voted for the original proposal. Another group opposed the route saying that the new LRT bridge crossing the North Saskatchewan River will have a negative impact on the river valley and the removal of the existing footbridge during construction (to be replaced by pedestrian space on the LRT bridge) would temporarily displace an existing river crossing. The city states that impact is minimal, no other alternative routes were suitable, and has proceeded with construction. Concerns in 2008 and 2009 over community impacts along the proposed west leg of the Valley Line and north leg of the Metro Line led to a larger debate over the vision guiding the various expansion plans, and the criteria used to select the routes. The adoption of a new signalling system (see below) for the Metro Line pushed back the start date from April 2014 to September 2015, when the line finally began operation at a frequency of 15 minutes, rather than 5. Trains only ran at a maximum of between the Churchill and NAIT stations, creating passenger delays and traffic congestion. An independent safety auditor cleared trains to run at their full as of February 19, 2017. Completed extensions Capital line On April 26, 1981, ETS opened a northeastern-bound extension of on the CN right-of-way to Clareview Station. In June 1983, the light rail tunnel downtown was extended by to Bay and Corona stations. The D.L. MacDonald Yard, between Belvedere and Clareview, opened in December 1983 to store and service the vehicles. The line was extended in September 1989 by to Grandin station (now Government Centre station, close to the Alberta Legislature). On August 23, 1992, the next extension opened from Grandin to University Station, partially via the Dudley B. Menzies Bridge, crossing the North Saskatchewan River with a lower level for pedestrians and cyclists, and partially via a tunnel into the station. Major upgrades to the Belvedere and Clareview stations were made in 1998 and 2001 respectively. On January 1, 2006, the line was extended south through the University Campus to Health Sciences Station, which is located at street level. On April 25, 2009, McKernan/Belgravia and South Campus stations were opened as part of the south LRT expansion, with Southgate and Century Park opening on April 24, 2010. The first of the new Siemens
