  • Tunnel Inspected Once per Year (Biennial and

Special Inspections)

  • Most current inspection has given the Tunnel an
  • verall rating of “Poor”
  • “Poor” rating is not an indication of an imminent

safety issue

  • Project scope to address safety, structural, and

geometric deficiencies.

and 2016 Supplement:

New One Lane Tunnel, Rehabilitate Existing Tunnels. New Two Lane Tunnel, Rehabilitate Existing Tunnels. Enlarge Existing Tunnels, while maintaining traffic, using Protective Shield. Construct a Temporary Bypass Tunnel, then Enlarge Existing Tunnels.

The 2014 Report and 2016 Supplement presents combinations of construction sequencing scenarios to assess traffic impacts and future level of service. Reconstruction can provide additional service life and meet future traffic flow capacity
