View from below of one part of Centre Street Bridge. One of the bridge's lions can be seen on the upper right hand side of the postcard. Bridge was built in 1916 at a cost of $375,000. It was designed by John F. Green, a pioneer engineer in the field of concrete bridges who also designed the Louise and Mission bridges. The four concrete lions, emblems, shields and buffalo heads on the Centre Street Bridge were designed by Scottish stone mason James L. Thompson who came to Calgary in 1910. He worked as a labourer for the City and as a hobby, carved a lion for his garden at 2109 Centre Street North. The bridge lions, modelled after those at the base of Admiral Nelson's Monument in Trafalgar Square, London, were cast on the construction site, hoisted and cemented into place.
