This decently-sized storm sewer was built in the late 1960s or early 1970s to bury the upstream elements of Duncan Woods Creek, a tributary of the German Mills Creek and ultimately the east branch of the Don River. Construction of this drain provided a conveniently located storm trunk sewer for new subdivisions, Seneca College and Fairview Mall, which were all being built atop the creek's watershed, and removed a ravine in a time when open waterways were still viewed primarily as a nuisance in suburban paradises of the sort that North York aspired to be. The lower part of this sewer is a fairly large, rectangular concrete box built in place from sectional panels, while south of Finch Avenue the drain takes the form of smaller, precast round pipes.

Soon after the main trunk of the sewer was installed, an arm was added to provide drainage for the section of Highway 404 in the vicinity of Finch Avenue East. This is also composed of round, precast concrete pipe, and includes a number of chambers with grilled ceilings to drain the margins of the highway.
