Stage 2 of Highway 417 expansion begins on schedule

11 July 2014

Public Service Announcement

Ottawa – Starting Friday, July 11 the Highway 417 expansion project will transition into the second and final stage of construction. The second stage of construction will focus on rehabilitating the median, as well as replacing the Lees Avenue and Vanier Parkway bridges using rapid replacement construction techniques.

Stage 2 construction will require traffic lanes to be reconfigured from the inside lanes to the outside lanes. Beginning tonight, traffic control barriers in the eastbound lanes will be reconfigured. Reconfiguration of the traffic control barriers in the westbound lanes are scheduled to occur overnight beginning as early as July 21. As the work is occurring overnight, traffic impacts should be minimal.

Bridge work, including widening and replacing the Hurdman and Belfast bridges and widening and rehabilitating the Central Transitway and St. Laurent Boulevard bridges will continue into the second stage of construction.

The first stage of construction began in May 2013 where construction activities focused on expanding the Highway 417 to create one additional lane in both directions, between Nicholas Street and the Split, including utility relocation, construction of related drainage works, roadside protection and retaining walls. Other significant works completed in stage 1 includes realigning the Highway 174 off-ramp to St. Laurent Boulevard, as well as the rapid removal of the Lees Avenue Bridge.

Motorists are reminded to respect the reduced speed limits and use caution when travelling through the construction zone. Signage will be in place to advise drivers of the lane changes and ongoing construction activity.

Many of these construction elements are weather-dependant and may be implemented later than the dates given above.

The Highway 417 Expansion project is scheduled to be completed in fall 2015. The additional lane will be used for bus rapid transit during the 2015 to 2018 phase of the Confederation Line construction. 

With all of the construction-related activities underway, residents are encouraged to be flexible with commuting times, stagger work hours or use other alternative means for travel. The public is asked to consider options such as transit, walking, cycling or carpooling.

    Hello: I do appreciate these notices. However, could you send them sooner, please? This one is dated for July 11th but I did not receive it until the 14th. Is this just a minor, one-off situation?…Jim Hurd
