HOOD CANAL BRIDGE CLOSURE MITIGATION PLAN
March 6, 2002









OVERVIEW
The east half of the Hood Canal Bridge is nearing the end of its service life. Beginning in 2003, construction on a new east half floating section, new approach structures and a widening on the west half will begin. During April/June 2006, the new east half will be floated into place requiring a six to eight week total closure of the bridge.

In February, 1999, two committees were formed from the PRTPO (the Hood Canal Bridge Stakeholders Committee and the Hood Canal Bridge Advisory Committee) to develop a closure mitigation plan. The two committees, with input from the public, developed a list of eleven proposed strategies for mitigation for the 2006 closure of the Hood Canal Bridge. WSDOT completed an analysis of the preferred options and built a proposal that utilizes a combination of the most effective strategies.

The proposed WSDOT mitigation plan included:
 


WSDOT determined this proposal provided predictable, dependable service that is multi-modal and lessens the impact to users of the Hood Canal Bridge during the replacement of the east half floating portion of the bridge. The options listed above could be provided within the funding limit of $10 million and among them are the options that rated the highest in an opinion poll taken at four open house meetings during September/October 1999, and at Hood Canal Bridge committee meetings in October 1999.

In February, 2002, the PRTPO met to vote on the preferred bridge closure mitigation options. However, the projected costs for the passenger-only ferry ($3 million) were actually $6.5 million. and the projected costs of the Port Townsend auto ferry to Kingston/Edmonds ($3.5 million) were actually $6.7 million.

The breakdown of costs are:

Passenger-only Ferry
                                      Water Side Costs                   Land Side Costs                       Transit
Foot Ferries                         $1,500,000                                     -0-                            $1,850,000
South Point                           $ 305,860                             $ 180,000                                  -0-
Port Gamble                          $ 315,860                           $1,430,000                                  -0-
Fred Hill                                    -0-                                    $ 900,000                                  -0-
Total:       $6,500,000

Auto Ferry
                                      Water Side Costs                   Land Side Costs                       Transit
Auto Ferries                         $3,074,000                                     -0-                             $2,100,000
Port Townsend                      $ 247,000                               $ 21,320                                  -0-
Kingston                                     -0-                                     $ 50,000                                  -0-
Edmonds                                     -0-                                    $150,000                                  -0-
Jeffco Airport                              -0-                                    $860,000                                  -0-
Total:       $6,700,000

The above costs assume no user fees. There would be no charge for auto or passenger-only ferries, and no charge for transit services.

Based on these new cost figures, only one ferry option could be enacted.

Passenger-only Ferry

                                              Advantages                                                                       Disadvantages
                     Moves 2,700 passengers at the AM peak                                 Vulnerability to weather shutdowns
                     Flexible continuous service                                                       No automotive or truck capacity
                     Shorter runs-approximately 20 minutes                                    Requires pre-staging of autos
                     Less impacts to Port Townsend                                                Requires people to change routine
                     Large areas available for parking at
                     Port Gamble and Sunshine Pit
                     Service will operate in low traffic areas
                     with minimal impact
                     Smaller passenger loads are more compatible
                     with transit and road systems

Auto Ferry
                                          Advantages                                                                          Disadvantages
                    Provides auto and truck passage directly                                 Will overload the Port Townsend ferry terminal
                    from Port Townsend to Kitsap Peninsula                                 and city traffic in the vicinity
                    and mainland                                                                            Requires transit system to deliver 1,400
                    Provides temporary improvements to                                       passengers from park & rides to Port Townsend
                    auto holding areas in Port Townsend                                       ferry dock for one sailing
                    Can run in all weather                                                              Requires holding area on or in vicinity of Port
                    More readily accommodates tourist traffic                               Townsend dock for up to 1,400 passengers
                                                                                                                     Serves only a small portion of auto/truck traffic
                                                                                                                     Low flexibility of service

Based on the above, the PRTPO endorsed the Southpoint/Port Gamble passenger-only ferry option
