The Cape Horn Interchange, named after nearby Cape Horn Avenue, is a major interchange on British Columbia Highway 1 (Trans-Canada Highway), where it connects to Lougheed Highway (Highway 7), a heavily signalized thoroughfare in Coquitlam, Port Coquitlam, and Burnaby, and the Mary Hill Bypass (Highway 7B), bypassing the Coquitlam and Port Coquitlam sections of Lougheed Highway and forming the quickest route to Pitt Meadows and Maple Ridge. It also includes several exits to United Boulevard, a light-industrial and commercial road in southern Coquitlam.
The Canadian Pacific Railway mainline roughly follows the alignment of Lougheed Highway in this area, and skirts the south and east sides of the interchange.
This interchange contains several "types" of interchanges within it, but overall is a hybrid stack interchange. The junction between Highways 1 and 7 is a 4-way, 3-level stack interchange, with two turning movements left out (eastbound Hwy 7 to westbound Hwy 1 and eastbound Hwy 1 to westbound Hwy 7). Vehicles making those movements should use the Brunette Avenue Interchange, 4 km west of the Cape Horn.
Hwy 7B (more commonly known as the Mary Hill Bypass) has a half-single point urban interchange (westbound exit, eastbound entrance) with United Boulevard, and then westbound 7B merges onto Highways 1 and 7 westbound. Traffic from eastbound Highways 1 and 7 each have a free-flowing ramp to Highway 7B east.
Just north of the Hwys 1/7 junction, United Boulevard intersects Lougheed Highway with two free-flowing ramps (eastbound Lougheed to southbound United, northbound United to westbound Lougheed. All other turning movements must be made over an overpass and down a small connecting road to a light (which forms a continuous green t-intersection with the Lougheed Highway mainline). Via this connection, traffic from Mariner Way and Cape Horn Avenue (two major residential roads in Coquitlam) may also access the interchange.
