Here is how I would design the area. It really transforms the whole south end...
New flyover of Hunt Club. Community connections would still be possible at Cahill/Bank and Albion/Bank. Hunt Club Manor would still be accessible by a new service road, while the car dealership would be removed.
SPUI at Hunt Club in order to reduce the number of signals and the footprint of the interchange. The strip plazas in the SE corner of the interchange are removed to fit the realigned Hunt Club. However, significant land would remain adjacent to Bank and that would be prime for a streetside redevelopment. That would allow for a new mainstreet feel of southern Bank. The strip plaza in the SW corner is not needed, but discussions with the owners might allow for a total redevelopment. Although the spacing is tight, IMO it is probably acceptable for 80 km/h.
Daze Street/Bridle Path Drive:
New flyover of Hunt Club. Community connections would be possible at Bank/Daze or Bank/Albion. The parking lots would be reconfigured to allow for access to Mountain Crescent.
Downpatrick Road/McCarthy Road:
New flyover of Hunt Club. Community connections would be possible at the new Uplands interchange (which would NOT be directly at Uplands Drive, but rather indirectly accessible at Gibford Drive, in order to minimize community disruption). The several houses fronting Hunt Club would either need to be back-fronted or removed.
Airport Parkway area:
It is assumed the Airport Parkway is twinned through the area, but it does not necessarily have to be for its entire length, just around the interchange. The current SPUI would be redesigned into a diamond to maintain the ramps while eliminating the traffic signals. A new loop ramp would allow for S-->E movements and a new flyover ramp would allow for E-->N movements and access to Hunt Club Loop for eastbound buses. Westbound buses would have an easy ramp, while buses headed westbound would have to exit onto Bank Street (alternatively, a new bus ramp could be built skewing across the Airport Parkway).
There is no access to SB Airport Parkway from WB Hunt Club, and no access to WB Hunt Club from NB Airport Parkway. Those movements would have to be done via Uplands, due to space issues.
