Inlet in flood plain west of Highway 410

Great Expectation

Highway 410 Culvert

Water/Sewershed:
tributary drainage of Little Etobicoke Creek
Etobicoke Creek watershed

Construction Details:
RCP (3000mm) with a series of internal waterfalls

This drain is in Mississauga, and serves to route a small stream and surrounding flood plain beneath the sprawling 410-403-401 highway junction and east to an outfall into Little Etobicoke Creek. It is mainly significant for a large waterfall chamber beneath the grassy median of the 410 -- no catwalks were provided to permit access between the top and bottom of the fall within the drain, so traversing it requires one to exit through a manhole on one side of the waterfall and re-enter through another lid about fifteen metres away, all this as transport trucks speed past on both sides.

The inlet structure is also very interesting, and the landscape around it is beautiful at night.
