We find the engineering of canal systems to be fascinating. In the opening parts of this walk, we showed lots of bridges that cross the canal (carrying pedestrians, cars, and trains). But some canals, such as the Grand Union, in turn cross over obstacles such as roadways. But canals do not have bridges, they are called aqueducts instead.
North Circular Road
This is the North Circular Aqueduct, which makes a lot of sense since it crosses the London North Circular Road. While the approach to the aqueduct is quite industrial and somewhat noisy, it did not prepare us for the view of all of the traffic as we looked down from the aqueduct.
