The diagram below gives a high level overview of the three shortlisted corridor locations in the 2007-2013 Interprovincial Crossings Study. A brief written description of the work involved in constructing these corridors is provided below the picture as well as a link to a Google maps version which can be used to zoom in for greater detail or to see street level views.
The 3 corridors are referred to often as follows:
Corridor 5: Kettle Island Corridor 6: Lower Duck Corridor 7: Gatineau Airport / Mclaurin Bay
Here is a link to a Google maps view of the three corridors. (note the corridor lines on this map are approximate. By putting them on Google maps it is possible to zoom in to greater levels of depth as well as see satellite views of the area).
April 2012 Update: The Study Partners have now posted detailed diagrams of the preferred routing each of the 3 candidate bridge locations. These large size detailed files are available for viewing and download at this website: http://www.ncrcrossings.ca/index.php/resources/43-focused-segment-community-meetings
For Corridor 5, Kettle Island the work would include:
Reconstruction of the Aviation Parkway / Highway 417 / Ottawa Road (OR) 174 (split) interchange;
Widening the Aviation Parkway, where necessary, to a 4-lane divided cross section;
Creating a 'mini' interchange with Aviation Parkway overpass of Ogilvie Rd (similar design to Airport Parkway overpass of Hunt Club Rd)
Constructing a new intersection with the Rockcliffe Parkway;
A new interprovincial bridge with long spans (approximately 200 m) over the navigational channel;
A new road section northerly from the bridge to Maloney Boulevard; and
Creating a 'mini' interchange with overpass of Maloney Boulevard (similar to Ogilvie Rd overpass/interchange described above)
Widening Montée Paiement over Autoroute 50 to a 4-lane structure and creating a parallel 'service road' along Montee Paiement to service driveways of homes currently accessing Montee Paiement
Reconfiguring the interchange of Montee Paiment with Hwy 50
For Corridor 6, Lower Duck Island, the work would include:
Widening OR 174 to 6 lanes, from a brand new interchange at the bridge approach to the split at Highway 417
A new interchange at OR 174
A new roadway link from OR 174 north to a bridge across the Greenbelt
Relocating Rockcliffe Parkway
A new interprovincial bridge spanning the Ottawa River and wetlands
A new roadway link northerly from the bridge to Maloney Boulevard
Widening Lorrain Boulevard from Maloney Boulevard to Autoroute 50, including a new railway structure
For Corridor 7, Gatineau Airport/McLaurin Bay, the work would include:
Widening OR 174 to 6 lanes, from new interchange at bridge approach to Highway 417
A new interchange at OR 174
A new roadway link from OR 174 to bridge across the Greenbelt
A new interprovincial bridge spanning the Ottawa River, Murphy and McLaurin Bays and wetlands and the Blanche River
A new roadway link northerly from the bridge to Autoroute 50, including new railway structure
A new interchange at Autoroute 50
The scope of work for Phase 2 of the EA would involve environmental analysis of the three corridors, comparative analysis and evaluation, selection of the recommended corridor including proposed mitigation measures to reduce any negative environmental effects, and seeking of appropriate environmental approvals.
Alternative Bridge Corridors:
A fourth bridge corridor option, commonly referred to as the “Canotek” option, had been proposed during the 2007-2013 Interprovincial Crossings Study.
It is located in the general vicinity of options 6 and 7
It would skirt the east side of Canotek Industrial Park and would cross the river immediately to the east of Lower Duck Island. The purpose of this proposed new routing is avoid impact on the greenbelt by constructing the road instead on the west side of Green's creek
The routing on the Quebec side would pass through lands currently used as a quarry to Hwy 148, and then
follow Hwy 148 further eastward and then north through currently undeveloped lands to connect with Hwy 50 at a newly constructed interchange near the existing industrial area near blvd. de l'Aeroport.
The consultants for the NCC claimed to have accommodated this option in Ontario by widening Corridor 6 to include part of Canotek Industrial Park, but did not include the area of this proposed route in the corridors considered on the Quebec side.
