Between PTH 190 and the Perimeter Highway, PR 221 has been incorporated into the CentrePort Canada road network. As such, it has recently received upgrades and now has RTAC status, allowing for full tractor-trailer access between PTH 190 and PTH 101.[2] Prior to the construction of CentrePort Canada Way, PR 221 linked with Inkster Boulevard (Winnipeg Route 25).[3][4] Until the 1980s, PR 221 previously extended west of Marquette to PTH 26 along what is now Jubilee Road.
