Highway 417 – Widening & Ramp Closures

UPDATE: July 2015

Blair Road lane configuration:

The new lanes between the Blair off-ramp (westbound) and Gloucester Centre entrance are associated with the upcoming Transitway closure to accommodate bus access to Blair Station from the highway.

The reconfiguration of lanes on Blair Road on the overpass is to provide a second left turn lane to improve capacity for buses. This, along with a transit lane on highway 174 and a transit only right turn lane at the highway 174 eastbound off-ramp/Blair intersection, are all transit priority measures to address the transitway closure for the LRT work.

Please note that the City has widened the 174 eastbound off-ramp to Blair Road, in order to provide a transit only right turning lane (onto Blair Road) at the intersection.

417 to 174 ramp closure:

The City has been planning for some time to shut the 417 westbound to 174 eastbound off-ramp until the Confederation Line opens in the summer of 2018. This is to allow for the use of the ramp as part of the City’s transit service re-alignment while the transitway is converted to Light Rail Transit.

This closure is required for safety reasons; to avoid conflicts between the high number of buses operating through this area during peak hours (120 buses per hour at peak) and regular vehicular traffic that would be trying to merge off the ramp.

We recognize that this closure will place pressure on Innes Road and for that reason have commenced its widening by an additional lane in the eastbound direction so that it will be able to accommodate the anticipated increased eastbound traffic.

The alternate routings available (Innes EB to Blair NB to Hwy 174 EB; Innes EB all the way to Orleans; and Hwy 417 WB to Aviation NB to Ogilvie EB).

This work is being done as part of the Highway 417 expansion project, which began in May 2013, and will add an additional lane in each direction between Nicholas Street and the 417/174 Split. The additional lane will be used for rapid bus transit during the 2015-2018 phase of the Confederation Line construction.
