The last time I was beneath Plaza Bridge was back during Nuit Blanche. Some weeks back I took shots again during the daytime. The bridge has been here for many years, but work was done in the 90s to open this space below up, including the installation of the staircase here from the street above.
It's a fine use of space along this stretch of the Rideau Canal, between the Ottawa Locks and the National Arts Centre. The acoustics are excellent, and the pathway makes for an interesting place for a stroll. This area is often used by photographers for wedding parties.
The stones you see along the path are still the foundations of the original Sapper's Bridge that crossed the Canal here; it gives you an idea of how much the road above has been elevated from the 19th century.
On the north side of the walkway, we come out to the Ottawa Locks, and the lockmaster station. I've long since lost track of the amount of times I've passed through here and down along the locks.
