Condition of Existing Tunnel 5
Opened in 1959
Designed to highway
standards of the 1950s
Electrical/mechanical
system is 50+ years
30+ year old counterflow
system
Partial seismic upgrade
completed spring 2006
Vulnerable to seismic
event; 1950s approach
Additional seismic
upgrades are high risk

Project Scope 13
![Page 14: Massey replacement briefing slides](https://reader038.vdocuments.us/reader038/viewer/2022102323/5695d05b1a28ab9b0292239e/html5/thumbnails/14.jpg)
Bridge Concept 14
• 3.3 km long
• 660 m clear span
over the Fraser River
• 200 m high towers
• 2-way navigation
channel with 57 m
clearance
• 100 year service life
• Optimize lifecycle
performance
• Design for future
rapid transit
• 34,000 concrete
trucks
• 50,000 t rebar
• 30,000 t steel
• 66 km of pile length
• 18,000 t asphalt
![Page 15: Massey replacement briefing slides](https://reader038.vdocuments.us/reader038/viewer/2022102323/5695d05b1a28ab9b0292239e/html5/thumbnails/15.jpg)
Major Bridges in the Lower Mainland 15
![Page 16: Massey replacement briefing slides](https://reader038.vdocuments.us/reader038/viewer/2022102323/5695d05b1a28ab9b0292239e/html5/thumbnails/16.jpg)
1 Dedicated transit/HOV lanes
3 Regular traffic lanes
(same as today in rush hour)
1 Lane for slow, merging traffic
Benefits:
• Improved merging safety
• Reduced weaving
• Reduced congestion/increased
reliability
• Improved emergency response
access
Why Five Lanes in Each Direction? 16
Four lanes in each direction
would result in congestion on
opening day

What Happens at the Oak Street Bridge?
• Morning queues will continue as they do today; traffic patterns
may change somewhat but no significant change in total traffic
• 60% of tunnel users end their trip in Richmond
• Efficiency of Oak Street Bridge will continue to be governed by traffic
lights at 70th Street
• Traffic volumes on the Oak Street
Bridge have been relatively constant
or declining over the past decade
(Canada Line effect)

no congestion, efficient
merges/lane changes
• Average commuter will
save 25 to 35 minutes
per day
• Travel time savings and
reliability benefits – more
than $70 million in the first
year; growing annually
![Page 33: Massey replacement briefing slides](https://reader038.vdocuments.us/reader038/viewer/2022102323/5695d05b1a28ab9b0292239e/html5/thumbnails/33.jpg)
Why Tolling?
• Significant benefits for those using the
new Bridge
• Allows project to proceed now, without
taking away from government funding
for health and education
• Similar format to Port Mann Bridge
• Working with federal government on
potential contributions

Anticipated Effects of Tolling New Crossing 34
TUNNEL TODAY
“Rush Hour” (6-8 hours):
• The Tunnel and Alex Fraser
Bridge (AFB) are heavily
congested
Midday (6 hours):
• Tunnel, AFB and Richmond
Connector near congestion;
incident sensitive
Overnight/Weekends:
• Free-flowing traffic
WITH A NEW BRIDGE
Rush Hour:
• New Bridge free-flowing
• Traffic in queues at AFB will
move to new Bridge
Midday:
• Limited traffic diversion to
AFB due to congestion on
East/West Connector
Overnight/Weekends:
• Some traffic diversion to AFB
![Page 35: Massey replacement briefing slides](https://reader038.vdocuments.us/reader038/viewer/2022102323/5695d05b1a28ab9b0292239e/html5/thumbnails/35.jpg)
Won’t People Use Alex Fraser Bridge?
Port Mann Experience:
• Traffic by time of day:
• Rush-hour traffic increased
significantly
• Midday and overnight traffic
decreased
• Weekends:
• Traffic volumes decreased
• Total average daily traffic:
• Traffic volumes decreased in 2013/2014 after tolling started in 2012
• Traffic has increased each month in 2015
