Regarding the Airport Parkway and Lester Road, that is a real challenge. The big problem, IMO, is solving the upstream issue. Bronson Avenue cannot be widened, and a narrowing would be desirable (but impossible in the current situation). That means the solution is separating the Airport Parkway from Bronson Avenue. My recommendation:

* Reconstruct Booth Street and Rochester Street as a one-way couplet, with 2 lanes on each north of Raymond and 4 lanes on each south. As a business area, the residential impact would be lower.

* To prevent cut-through traffic in residential areas, Booth Street would be discontinuous to all traffic except for cyclists and pedestrians at Albert Street (access closed off).

* Remove the 417 ramps at Bronson and shift them to Booth and Rochester, using Orangeville Street and Raymond Street as accesses.

* South of Carling Avenue, a vehicular tunnel with 6 lanes (3 in each bore) beneath Dow's Lake would connect Booth/Rochester to the Airport Parkway (now Bronson Avenue) north of Sunnyside Avenue. Trucks would be prohibited, as they are now on the Airport Parkway.

* An interchange (most likely a diamond or SPUI) would be built at Sunnyside Avenue, and the pedestrian crossing to the south would become an overpass. In general, the design would be a wide urban boulevard from the 417 to Carling and a freeway south of Carling.

* Once that is done, then twin the Airport Parkway.

* Concurrently, Bronson Avenue north of the Rideau Canal should be reduced to 2 travel lanes + parking, and the speed limit reduced to 40 km/h. The access from Highway 417 would be removed as well.

* The Bronson Avenue Bridge would narrow from 6 to 2 lanes, using the other space as plazas and a gateway to Carleton University. Bronson would go straight into the campus directly. Access to Colonel By Drive would be from a new connector road with an at-grade intersection or roundabout (replacing the current ramps).
