The Prince Edward Viaduct
Designed by Edmund Burke, Architect, and Thomas Taylor, Construction Engineer, Prince Edward Viaduct was opened on 18 October 1918. The viaduct joined Bloor Street and Danforth Avenue from Sherbourne Street to Broadview Avenue, to provide easy access to the rapidly expanding suburbs east of the Don River. The Bloor section, carried on an earthen embankment, stretches eastward from Sherbourne to Parliament Streets. The Don section, supported by a bridge 494 metres long, extends westward from Broadview Avenue. The Rosedale section, with a bridge span of 177 metres, forms a connecting link between them. On the recommendation of Jacob and Davies, Consulting Engineers, provision for a lower second deck was incorporated into the viaduct to carry subway trains. This foresight proved to be of inestimable value in building the Bloor-Danforth subway line 50 years later.
