A little perspective
Powell River vs Sydney Harbour Bridge: length comparison
The main arch span of Sydney Harbour Bridge is about 1.01 times the main-channel length of the Powell River.
The Powell River is a short river in British Columbia flowing from Powell Lake to the Salish Sea.
Sydney Harbour Bridge is a steel arch bridge in Sydney, Australia, connecting the city centre with the North Shore.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions.
