The spiral parkade driveway that meets the intersection of 2nd Street and 9th Avenue SW will be partially blocked from view by Calgary's newest and longest Plus-15 walkway. The curving structure will stretch from Penn West Plaza to Gulf Canada Square, finally implementing a link envisioned by the original owners of the complex.

The Calgary Herald reports that the project required permission from several actors, including the Calgary Parking Authority and CP Rail, as the company has a ground-level vehicular entrance to its shed.

Morguard Real Estate Investment Trust, who purchased Penn West Plaza in 2012, is now executing the pendulous design proposed by Abugov Kaspar Architects. The span will be penetrated by a single mast with radial cable supports, while the northern side of the bridge will be covered in LED-illuminated exterior panels. The south wall will be capable of hosting public art and other displays, according to the architect's website.

The interior expression echoes the radial design of the exterior, with the $7 million walkway also including public furniture. The bridge is slated to be open and ready for pedestrians by the end of 2018.
