1. Meeting called to order
1.1 Welcome and presentation of the agenda.
2. Presentation of work updates and selected mobility options
2.1 Dan Genest and Geneviève Campeau presented the work under way and planned until spring 2018 for
the Nuns’ Island area and the mobility options chosen to complete it. A paper copy of the presentation was
given to every Committee member and the presentation was posted on the website:
http://www.newchamplain.ca/neightbourhood/november-28-2017/
3. Question period for Committee members
Actions/Measures Response
3.1 Details on the timetable of measures
implemented for mobility starting on
December 4 (Slide 38).
Starting on Tuesday, December 5, the improvements on Boul.
de l’Île-des-Sœurs will be operational.
Boul. René-Lévesque south (two lanes) will be closed starting
on December 5, and one lane on the northbound side will be
available at all times.
The only non-functional roadway on Slide 38 starting on
December 5 will be the access to Highway 10 via the Claude-
Robutel roundabout. This link should be functional by the
Christmas holidays.
3.2 Review of traffic studies conducted by
the various partners
Ms. Campeau explained that the studies conducted by the City
of Montreal and Infrastructure Canada involved the complete
closure of René-Lévesque Blvd. north and south. The
consulting engineer’s team mandated by the City of Montreal
had some differences in opinion, the main one involving the
impact of the closure on the roundabout approach (Place du

Commerce).
The current solution that involves maintaining northbound Boul.
René-Lévesque lanes during morning and afternoon rush
hours enables the problems with the incoming roundabout
leading to Place du Commerce to be resolved.
Three road closures lasting a few consecutive days are
planned in 2018, but SSL will first make some adjustments, if
needed (e.g. police presence) so that this type of closure
impacts IDS traffic as little as possible.
The three partners quickly agreed on maintaining northbound
rather than southbound lanes open in the morning and
evening. SSL mentioned the importance of working on finding
a solution and not on focusing on disagreements.
3.3 Effect of raising Highway 15 over Nuns’
Island (Slide 33) on the landscape, and
confirmation if this is new information.
Mr. Genest noted that after the construction of the new
highway and overpasses, there would in fact be some loss of
visibility from Pointe-Nord to Pointe-Sud, and vice versa.
Mr. Parenteau noted that the highway will be raised at the
former toll both, where the road is wider and the landscape
mainly consists of cement. The new sloped arrangement will
change the view and structure, and this is not an issue given
the current state of the landscape.
Mr. Genest noted that the raising of the highway had always
been planned, but had not been explained in detail. The
pedestrian tunnel will be at ground level at Boul. René-
Lévesque, with 3- to 4-metre embankment on either side of the
tunnel.
3.4 Impact of the raising of the highway at
Nuns’ Island and noise (Slide 33)
No increase in noise levels is expected.
Clarification: the distance between P10 (Boul. de l’Île-des-
Sœurs) and P12 (pedestrian tunnel) is 600 metres. The
distance between P11 (René-Lévesque) and P12 is about 450
metres. Therefore, the distance between P10 and P11 is about
1 km.
Ms. Campeau mentioned that the section shown on Slide 33 is
very sketchy. It may give the impression that there will be a
raised highway, but the change will be minimal. A section at
scale would be more representative in order to have a better
idea of the visual integration. Remember that this section was
done to clearly show the mobility issues at the highway on-
ramps for Nuns’ Island.
3.5 Information on the delivery of box
girders
Three means of transportation are used: by barge, by train and
by road, via the West Island: Highway 30, Beauharnois Bridge,
Highway 20 and municipal roadways, mainly used at night. We
recently obtained daytime authorization to make deliveries
using the municipal road networks.
3.6 Information on the closure of Exit 61 on
Hwy 15 North
This exit will have to be closed for two or three weeks. A detour
is possible via Exit 62 at La Vérendrye or Exit 60 at Gaétan
Laberge.
3.7 Possible reconfiguration of the new Exit
60 on Hwy 15 North and the name
“Wellington” used once again for the
Ms. Côté noted that the MTMDET’s naming criteria were
observed by SSL in naming the Gaétan-Laberge exit, and that
a request will be submitted to the government to add the name

exit of Wellington.
Ms. Campeau indicated that this is a temporary exit for the time
being, and that the final Exit 60, which is more user friendly
and longer, will be built next year.
Clarification: After rechecking the MTMDET’s standards,
Infrastructure Canada is confirming that the name “Gaétan-
Laberge” for Exit 60 complies with the standards.
3.8 Verdun residents notified regarding
access to downtown Montreal via
Gaétan-Laberge rather than Wellington
Mr. Parenteau indicated that Verdun residents were properly
notified, and that week after week they are using the access
more and more to get downtown.
3.9 Role of light rail transit system in the
raising of the highway at Nuns’ island
and route taken by the bus when
leaving Nuns’ Island.
Mr. Genest noted that the LRT requires a set gradient and a
less steep slope. The LRT could not use the existing
Champlain Bridge cause of the steep slope over the Seaway.
CPDQ Infra intends to build a bridge parallel to the Nuns’
Island bypass bridge, but this is not part of SSL’s mandate.
3.10 Cost associated with acceleration
measures versus late penalties.
The federal government wants the bridge to be completed as
soon as possible, i.e. in December 2018. This may involve
additional costs, but SSL wants to comply with the contract
date of December 2018.
4.0 Question period for the public
4.1 Bridge closer to the SAX condos by 20
metres and consideration of this factor
in the noise study.
Review of this question after the next presentation on the anti-
noise walls.
4.2 Champlain Bridge cannot be accessed
from Boul. de l’Île-des-Soeurs in Pointe-
Sud and procedure to prevent U-turns
in the roundabout.
Pointe-Sud users will have to access the Champlain Bridge via
Boul. René Lévesque.
When the roundabout is opened, there will be proper traffic
signs and a police presence to ensure compliance with the new
configuration and to sensitive road users. Police may be
handing out tickets.
4.3 Itinerary to use when Boul. René-
Lévesque is closed.
Electronic panels will clearly indicate the closures further
ahead on local roads with detour signs. U-turns will also be
allowed near the road closure.
The highways can be accessed via Boul. de l’Île des Soeurs
starting at 9:00 a.m. Access to the Champlain Bridge via Boul.
René-Lévesque will be available at all times, and this is the
recommended access for Pointe-Sud residents.
4.4 Mention the names of the streets
associated with the exits on the
communication tools and information
from SSL released by the partners.
Noted for the first comment.
SSL shares all the information with its partners so that they
release it on their networks. The information is available at the
following link under “Info-Travaux/Nouveau Pont Champlain”:

on-ramp and projected mitigation
measures in the event of congestion at
the roundabout when entering Nuns’
Island.
The on-ramp at Hwy 15N from the Claude Robutel roundabout
will remain open.
Congestion at Place du Commerce was to be expected due to
the closure of Hwy 15N traffic, which is no longer the case.
Since this traffic will still be possible during morning and

afternoon rush hours, it no longer has to be taken into account.
There will be a slight increase in traffic at the roundabout, but
this does not require constant police presence.
When the René-Lévesque corridor is completely closed (three
consecutive nine-day periods in 2018), police presence may be
necessary, but no other measures need to be taken for the
time being.
4.6 Concern as to the time taken by buses
to access Nuns’ Island and
determination that the changes made to
the network will favour Nuns’ Island
exits, but will not improve entry points.
Mr. Parenteau mentioned that the STM is fully aware of the
current situation and is attempting to find a solution, but adding
more buses will not solve the situation. In the event of a
problem, the resident is asked to contact the borough.
Ms. Campeau explained that two improvements will be
implemented shortly to help with access to Nuns’ Island: a lane
would be reopened on the Bonaventure Expressway in the
Champlain Bridge corridor (before or after the Christmas
holidays) and there would be a new reserved lane from
downtown Montreal to the bridge (around spring 2018) to help
relieve on-ramp congestion for Nuns’ Island residents.
4.7 Details on preserving the bicycle path
between Verdun and Nuns’ Island
No impact is anticipated. The aim is to open the new bridge
with a link for cyclists and pedestrians, with a new link on Nuns’
Island.
4.8 Information on the closure of Exit 57
South: when, for how long, and detour
This unavoidable closure was scheduled for 2017, with Exit 57
North serving as detour.
SSL is currently working on a solution that would allow a
temporary exit to be opened rather than closed. Rather than
being a long-term closure, there would only be a few closures
at night or on weekends, the time needed to create the
temporary on-ramp.
4.9 Work progress report and potential for
staying on schedule
12 of the 37 pier caps were installed.
Implementing acceleration measures will allow SSL to deliver
the bridge for December 2018.
4.10 Maintaining the pedestrian walkway on
Boul. René Lévesque.
SSL is in the process of determining what can be done to
maintain the walkway for as long as possible, and when there
are closures, SSL will look into setting up a shuttle system.
This will be presented at a later time.
*Since the Good Neighbourly Relations Committee meeting,
the decision was made to build a sidewalk in the René-
Lévesque temporary corridor that will be open during rush
hour.

4.11 Construction of an incentive parking lot
near the pedestrian tunnel on Nuns’
Island
There are no plans for an incentive parking lot, but there will be
a taxi, bus and car dropoff area.
Mr. Parenteau stated that public transit services on Nuns’
Island will be reviewed accordingly, with a closed route on
Nuns’ Island. This will be a major positive change for Nuns’
Island.
4.12 Improvements to lanes under the Hwy
15 overpasses and actual Nuns’ Island
rush hour from 7:00 a.m. to 10:00 a.m.
The position of the current abutments does not allow the road

determined with the Borough of Verdun and the City of
Montreal, and a counter was used to determine rush hours.
SSL and the partners are working together and have made
adjustments on numerous occasions to take into account
residents’ concerns.
4.13 Details on closure of Exit 57-S and
rerouting to Exit 57-N
The long-term closure of Exit 57-S is no longer being
considered and, if possible, a temporary on-ramp will be built to
maintain this movement.
In fact, SSL is in the process of studying the option of a
temporary on-ramp that would provide access to Hwy 15-S at
Pointe-Sud. There will only be a few closures at night and over
a few weekends via a detour route that uses Exit 57-N.
4.14 Details on access to the Champlain
Bridge from Pointe-Sud
Access to the Champlain Bridge via Boul. René-Lévesque
will continue to be available. This is the preferred access
to the Champlain Bridge at all times for Pointe-Sud
residents.
2018 will be an important year for communication. After
checking, information on the new Champlain Bridge can be
found on the Borough of Verdun’s website under “Info-travaux.”
SSL also has a website where additional information can be
obtained on mobility, roadwork announcements, newsletter,
etc.
5.0 Presentation on anti-noise wall updates
5.1 Chantal Côté presented an update on the anti-noise walls (see presentation at:
http://www.newchamplain.ca/neightbourhood/november-28-2017/
6.0 Question period for the public
6.1 Details on the height of the walls on
Slide 7 and reasons for the height
variations which are considered unfair
by some residents.
The height variations were determined based on the acoustic
modelling in order to comply with the noise criteria in the
contract. The decision was made to increase the wall height of
the Rue May area to recreate the effect of the demolished
Victorian houses that acted as a noise barrier for Rushbrooke
and Jacques-Lauzon street residents.
An attempt was made during the year to increase the wall
height, but the final solution was to maintain the walls planned
in the noise simulations, except for the former Rue May, where
wall height was increased.
After the partners finished their discussions, Mr. Parenteau
noted that the height of the walls had to be significantly
increased and an overly large barrier created to reduce noise
levels, which resulted in a solution that was an acceptable
compromise between the number of decibels and wall height.
There were a lot of expert opinions involved to reach
acceptance in order to not adversely affect the residents’
quality of life, from both an acoustic and visual perspective.
Mr. Ponton mentioned that with respect to La Poudrière, the
gains are significant between the current and future situation,
where the sound environment is improved from 5 to 7 dBA.

6.2 Inclusion of barriers in the height of the
wall
The 1.14-metre barrier is included in the height of the wall. For
instance, if a wall is 2.5 metres high, this includes a 1.14-metre
barrier.
6.3 Information on wall materials at Evolo. The walls will be transparent.
6.4 Date of decision on anti-noise walls for
the Sud-Ouest sector, train noise on the
Butler Spur taken into account in the
noise studies, and discussions with CN
Within the next two months, the City of Montreal and
Infrastructure Canada should reach a final resolution on this
issue.
The railway tracks act as a noise barrier for Sud-Ouest
residents to protect them from highway noise.
This is why an informed discussion is required on this issue,
such as building a wall on the highway could solve a problem
but create another one, if the train noise is further reflected in
the Sud-Ouest sector by the wall.
Mr. Ponton mentioned that the problem of the train is taken into
account in discussions with IC. The train will not be an issue
and is taken into account in the current studies.
6.5 Follow-up on the pedestrian overpass
to access the St. Lawrence from the
Sud-Ouest area and fatigue regarding
the time taken by the City of Montreal to
respond to the various issues.
Mr. Ponton noted that this is still in the City’s plans for these
investment projects. From the very start of the process, the
opinion of Sud-Ouest residents will be requested and will be an
active part of the solution.
The City of Montreal is taking the request seriously. The City,
as it manages public funds, will conduct a feasibility study to
meet the major needs expressed by residents regarding
access to the St. Lawrence. This issue is a priority for the City,
but not from a timetable standpoint since Gaétan-Laberge
boulevard is already built. A pedestrian overpass over the new
Gaétan-Laberge boulevard will be reviewed and not a tunnel.
6.6 Determination of an increase in noise
for Cours des Fougères residents: 55
dBA post-project versus 52 dBA pre-
project (Slide 8)
Noise levels in this area will comply with the 55 dBA
requirement stated in the contract. 3 decibels or less are barely
perceptible. Measurement point B (Slide 8) is a single
measurement point that touches a block of houses.
6.7 Removal of the anti-noise wall despite
the new Nuns’ Island bridge being
much closer to the Sax condos and
information on when ambient noise
measurements were done: with the
former bridge or with the bypass bridge.
Despite the bridge being closer by 20 metres, traffic noise is
not as close, since the multifunctional path (pedestrians and
cyclists) and the off-ramp to Nuns’ Island are on the Sax side.
Mr. Parenteau stated that the bridge is in fact closer, but that
the traffic lanes that generate noise are roughly at the same
location as before. If you place the two bridges (old and new)
on top of each other, you can see that the driving surface is at
the same location.
IC will confirm when the noise measurements were made:
before or after the former Nuns’ Island bridge was closed.
Mr. Ponton stated that adding the fourth lane (which is less
congested) as well as having northbound traffic use another
deck located further east of the former bridge are factors that
help reduce the ambient noise generated by the new structure.

action plan, gives top priority to this issue, and that it will be
closely monitoring the landscaping for the entire project in the
coming months.
6.9 Procedure for maintaining the
transparent anti-noise walls
SSL has already indicated that it is easier to maintain an
opaque wall than a transparent one. SSL has a 30-year
performance obligation; therefore, the wall needs to be
transparent 25 years from now. Transparent walls were
installed at some locations for better visual integration and to
enable light to pass through.
6.10 Highway 15 opened to traffic without
any anti-noise walls
SSL already indicated in April 2017 that it was possible that
Highway 15 would be opened to traffic without any anti-noise
walls given that discussions and studies were still under way
with the partners.
The temporary anti-noise walls were kept to mitigate the
current noise, and the permanent anti-noise walls should be
installed in the spring to complete the southbound corridor.
6.11 What are 5 dBA like A difference in 5 dBA is perceptible, but less than 3 dBA is
barely perceptible.
The February 3, 2016 presentation on noise management
shows an explanatory diagram of the noise sources and their
intensity. Here is the link for the presentation:

6.12 Information on the height at which noise
measurements are taken and the
upward noise reverberation for Pointe-
Sud on Nuns’ Island (Cours des
Fougères)
This is based on industry standards: 5 m from a façade and 1.5
m from the ground.
This is not the industry standard for second and third floors.
Given the distance of the wall in relation to the Pointe-Sud
homes on Nuns’ Island, the reverberation does not apply.
6.13 Information on the asterisks on the
slides for the Rue May area (Slide 7)
and location of the former homes on
Rue May in relation to the future anti-
noise walls.
At some locations, the ambient noise was calculated based on
the noise curves (hence, from an extrapolation) and not from
actual measurement points. (The resident mentioned that
measurements had been taken at his home.)
Ms. Côté suggested that the resident leave his contact
information in order to obtain a more precise and detailed
response.
