Recommendations for new BC government

  • Take time to make informed decision regarding

George Massey Tunnel Replacement Project

  • Address current tunnel safety concerns, ensure

tunnel functions safely while in use

  • Review and comment on significance of Hwy 99

as lifeline corridor for earthquake emergency response

  • Review options for tunnel decommissioning,

including option to leave tunnel in place

  • Delta staff to provide whatever assistance

required to facilitate process

Time for Review

  • New BC government should extend contract

award process for new bridge to review all technical information and project rationale

  • 145 technical and scientific reports = 14,000 pages

– New BC government should make its own informed decision

Immediate Safety Concerns

  • Any replacement option is at least 5 years away
  • Immediate safety issues include:

– Electrical system deficits: Original system still in use despite 30 year design life; may fail without warning, difficult or impossible to obtain parts – Deteriorating concrete: netting has been installed to prevent spalling concrete falling into traffic – Frequent damage to sprinkler system due to insufficient over-height vehicle warning system – Ageing ventilation system is causing extremely poor air quality inside the tunnel

Lifeline Corridor

  • Hwy 99 is classified as a ‘critical’ and ‘key’

route for disaster response

  • Only Hwy 99 and Hwy 1 are ‘lifeline corridors’
  • Lifeline corridors provide:

– Critical access to staging areas like major airports – First priority for initial reconnaissance and road response and restoration

  • Delta is seeking review and comment on the

significance of the Hwy 99 corridor for emergency response

Tunnel Decommissioning

  • Current proposal includes decommissioning

and removing the tunnel once bridge is open

  • Other options exist, including leaving the

tunnel in place (potentially allowing it to fill with water), which may:

– Be less costly – Be less environmentally damaging – Address concerns related to dredging the Fraser River to accommodate larger ships

Conclusion

  • Immediate action is needed to:

– Alleviate tunnel traffic congestion – Improve transit and alternative transportation options south of the Fraser River – Address seismic, emergency response, and public safety concerns

  • The new BC government should be afforded the
  • pportunity to make its own informed assessment
  • f the alternative options regarding the George

Massey Tunnel replacement
