Now used by the Ottawa O-Train, the decision fifty years ago to eliminate level crossings along the rail line, thereby constructing a tunnel under Dow’s Lake to replace the level railway bridge, changed the face of the western part of town. Here from the Ottawa Citizen article 13 June 1961, the announcement of the planned work.
Railway Tracks Going Under Canal; Begin Work in Fall; Finish 2 Years
The government has approved the depression of the CPR Prescott railway line across the city’s West End.
Expected to start in the fall, the $3,600,000 project will see the line go under the Rideau Canal by tunnel and by open cut from the canal to near Gladstone Avenue.
Not a level railway crossing will be left in the section concerned.
