Olde Towne Beverley is a neighborhood located in Edmonton's northeast. It has several murals depicting its history.
This one shows the Grand Trunk Pacific Raliway Bridge which was built in 1907 and is still in use today by the CN Railway.
Great mural! Like @pattyblue I was puzzling out the difference in the sky and thinking you had made a composite with one photo laid over another. Then I reread what you said in your explanation and realized what it really is. Good to see there were others who were thinking it was real.
