Existing Challenges

  • Collisions
  • Congestion
  • Unreliability
  • Seismic vulnerability
  • Tunnel dimensions

sub-standard

  • No capacity for

cycling or walking

  • Impacts on:
  • People
  • Goods
  • Jobs
  • Tourism
  • Transit users

Bridge Concept

14

  • 3.3 km long
  • 660 m clear span
  • ver 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

SLIDE 16

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

  • pening day

Bridgeport Road to Highway 91

  • 200 lane km of roadway
  • 50 km of new dedicated

transit/HOV lanes

  • Replace 3 interchanges
  • Construct new bridge
  • Replace 5 overpasses
  • Decommission Tunnel

slide-19
SLIDE 19

Project Scope – Transit

  • 50 km of new dedicated transit lanes
  • Transit stops integrated with the

Steveston Highway and Highway 17A interchanges

  • Dedicated transit ramp from Highway

99 to Bridgeport Road

  • Safe and reliable transit access to

Canada Line at Bridgeport Station

  • Allowance for future rapid transit on

the new bridge

  • Highway 99 is already

a major transit route

  • One bus through the

tunnel every 3-4 minutes

  • More than 10,000

transit riders daily through the tunnel

  • Highest transit use of

any Fraser River road crossing

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

  • r declining over the past decade

(Canada Line effect)

Benefit/Cost Analysis

  • Quantified User Benefits:
  • Congestion reduction, travel time savings, improved

reliability, vehicle operating cost savings

  • Traffic safety (35% reduction in collisions)
  • Reduced seismic risk
  • Non-quantified User Benefits:
  • Cyclist/pedestrian, transit, marine traffic

improvements

  • Long-term economic development

31

Cost: $3.5 billion Benefit/Cost Ratio: 2.1 to 1

Travel Time Savings

32

TUNNEL TODAY

  • Rush Hour:
  • at capacity
  • totally congested 6-8 hrs/day
  • Midday:
  • near congestion
  • incident sensitive

WITH A NEW BRIDGE

  • Free-flow conditions – safer,

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

slide-33
SLIDE 33

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

SLIDE 35

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

Environmental Benefits

37

  • Transit enhancements to increase ridership
  • Multi-use pathway to encourage cycling/walking
  • Less idling; reduced GHG emissions
  • Restoring Green Slough to historic alignment
  • Bio-filtration marshes for stormwater

management

  • Environmental enhancements in Deas Slough
  • Improvements to Millennium Trail
