Centre Street Bridge
One of the great places to walk in Calgary is Prince's Island Park, which is an urban green space on an island in the Bow River. From the park, one has a great view of downtown Calgary, the river and the Centre Street Bridge. This bridge was originally built in 1906, but was heavily damaged in a flood in 1915. It was re-built and opened a year later. It's one of the main entry points into downtown from the northern part of the city and is famous for the four stone lions that mark its entrances.
Cars travel across the river above and below the main span of the bridge. A walking and biking path also crosses underneath.
I was on the island the other evening and couldn't resist drawing it.
