STRUCTURAL REINFORCEMENT AND REPAIRS

Major work on the Champlain Bridge

Installation of 48 trusses

Replacement of 11 joints

Repairs to 6 piers+

270,000+ hours workedat Champlain Bridge work sites

Highly complex workModular trusses+ 4 m high and 78 m long

+ 56,000 kg!

Constant structural monitoring

A STRUCTURE AT THE END OF ITS SERVICE LIFE THAT HAS BENEFITED FROM MAJOR CORRECTIVE MEASURES

Findings from the 2016 inspection

+ Structural integrity maintained

+ Condition of edge girders generally deficient

+ Repair work to improve components (e.g., foundation units, expansion joints)

+ New Integrated Grading System (IGS) to assess the impact of the

reinforcement systems

#OurProjects

+ Work blitzes completed a week ahead of schedule

+ Bridge’s lifespan extended by 75 years

REINFORCEMENT OF THE STEEL STRUCTURE

#OurProjects

+ Replacement and reinforcement of steel members

and reinforcing plates

+ Existing rivets keeping the assemblies in place are

removed and replaced with bolts

+ 80 workers at our sites 7 days a week

+ Major program to extend the service life

UPGRADES

Major project to reinforce the metal structure,

which dates back to the 1920s

ENVIRONMENTAL PROJECT TO PROTECT THE RIVER

+ 95% of work complete in the west sector

+ 32 pumping wells installed along the shoreline to create a hydraulic barrier

+ Run-in of the contaminated water processing system in December

Champlain Bridge Ice Control Structure

#OurProjects

NEW BICYCLE PATHAND DEVELOPMENT OF APPROACHES

950 trees and shrubs planted to revitalize the approaches

Melocheville Tunnel

#OurProjects

TUNNEL REHABILITATION

+ New structural reinforcements

+ Heated cables added to keep ice

from forming on the pavement

+ Waterproofing of concrete

surfaces

+ New intelligent transportation

system (ITS) to keep overheight

vehicles out of the tunnel and to

detect incidents with video

analysis

COMPLEX CHALLENGESProactive and responsible management

18

Management of major work

#OurProjects

DAILY MONITORING AND COORDINATION

+ Closures optimized by combining work

+ Proactive use of traffic lights on the Champlain

Bridge to redirect heavy vehicles and limit

required closures and restrictions

+ 30% fewer traffic closures and restrictions on

our network in 2016

WORK BLITZES REALLY WORK! Work blitzes saved 7,300 hours of closure time on the

Champlain Bridge.

19

+ Ongoing communication with traffic reporters and the media,

interviews and on-site tours

+ Text message alerts for major closures or significant incidents

on our network

+ Integrated dashboard at www.JacquesCartierChamplain.ca:

live traffic conditions, planned work, traffic cameras,

major work alerts

+ Tweets about closures and information about each structure:

Bicycle path network

#OurProjects

WINTER BICYCLE PATH ON THE JACQUES CARTIER BRIDGE

+ Goal: Make the path safe for cyclists of all skill levels

+ CIMA + hired to conduct a feasibility study

+ Findings: - Complex slopes, curves, geometry and isolated areas

- Difficult weather conditions above the river (black ice common)

- No pavement surfacing on which to spread de-icing salts

- Environmental restrictions related to snow removal

- Risk of falling ice from the steel superstructure

+ Recommendation: Optimized period in the spring once

the weather allows

22

Improvements to the existing network

#OurProjects

SEPARATE PEDESTRIAN / CYCLIST AREAS

+ Pedestrians and cyclists have to share the path,

which can be difficult for both types of user

+ Pedestrians and cyclists go at very different

speeds

+ The multipurpose path is very narrow compared

to the standard

+ Developments to improve pedestrian access

starting in spring 2017

+ New safety measures deployed on the entire

network

23

Planning for 2017

#OurProjects

FEWER MAJOR CLOSURES OR RESTRICTIONS NEXT YEAR

+ Optimized work from the river or the

shore

+ Coordination with other project

authorities to limit the impact on the

network

+ Blitz required on the Champlain

Bridge for the expansion joints

+ Continuation of the steel program on

the Jacques Cartier Bridge

+ Ongoing major maintenance program
