While progress on Toronto's Eglinton Crosstown LRT has been very much one step forward, two steps backward as of late, work on the Ontario Line subway is going forth full steam ahead, with the provincial government announcing another pivotal moment in the route's construction on Thursday. The shaft will eventually be the point where trains will switch from the route's below-ground to (controversially) above-ground segments. This step comes after work on the line's first tunnel launch shaft began at Exhibition Station last year. Metrolinx has fittingly declared 2025 to be the "year of digging" for the Ontario Line, which will run 15.6 kilometres total, spanning 15 stops from Exhibition to the former Science Centre hub, now renamed Don Valley Station. When the new route finally opens in 2031 after about a decade of construction, it is expected to see some 388,000 boardings each day.
