Sections of Bloor Street near High Park was still undeveloped in the early part of the 20th Century. Sections along High Park required infill to eliminate the natural deep valleys in the area. On the eastern terminus Bloor ended at Sherbourne Avenue at Rosedale Valley and where once the Sherbourne Blockhouse stood. A small footpath from Howard Street was the only means to reach the eastern end of the valley to continue along Danforth Avenue until the Prince Edward Viaduct was completed in 1918.
