Bridge Corridors


The diagram below  gives a high level overview of the proposed corridor locations. 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 corridor 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 overpass of Ogilvie Rd
  • Constructing a new intersection with the Rockcliffe Parkway; 
  • A new interprovincial bridge with long spans (approximately 200 m) over the navigational channel; 
  • Creating a 'mini' interchange with overpass of Maloney Boulevard
  • A new road section northerly from the bridge to Maloney Boulevard; and 
  • Widening Montée Paiement over Autoroute 50 to a 4-lane structure and creating a parallel 'service road' to service driveways of homes currently accessing Maloney Blvd
  • 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 bridge approach to Highway 417 
  • A new interchange at OR 174 
  • A new roadway link from OR 174 north to a bridge 
  • 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 
  • 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 involves 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.
