VASHON VS TACOMA NARROWS CROSSING ALTERNATIVES

COST COMPARISON

There has been a lot of discussions over the past years regarding the best solution to solve the traffic congestion problem that currently exists on the west side of Puget Sound. The Con Sol Group of Gig Harbor, Washington has produced several reports on this matter and will focus this report strictly on the cost benefits of a Vashon Crossing over the construction of a second bridge at the Tacoma Narrows Crossing.

Lets first take a look at the hard construction cost of each of these two alternative projects:

TACOMA NARROWS CROSSING CAPITAL COSTS

New Tacoma Narrows Bridge$330,000,0001
SR16 Road Improvements$ 89,910,0002
Parking Facilities$ 4,100,0003
Total$424,010,000

Constructing a new bridge with approach roads only solves a small portion of the problem. The other necessary element required to move cars across central Puget Sound and solve the congestion problem involves increasing the capacity of the existing ferry system:4

ADDED FERRY & TRANSIT CAPITAL COST TO TACOMA NARROWS BRIDGE ALTERNATIVE

Additional Ferry Vessels$ 835,500,0005
Ferry Terminal Improvements$ 54,000,0006
Transit Additions$ 1,300,0007
Additional Roadway Improvements$ 121,400,0008
Total$ 1,012,200,000

The combined total cost to relieve the existing congestion on the west side of Puget Sound is:

Total Tacoma Narrows Capital Crossing Cost $1,436,210,000

Now, let's look at the hard construction cost to solve the same problem using the Vashon Crossing Alternative:

VASHON CROSSING CAPITAL COST

Burien/Vashon Floating Bridge$530,500,0009
Fragaria/Vashon Suspension Bridge$512,000,00010
Burien Road Improvements$116,560,00011
Vashon Road Improvements$111,390,00012
Kitsap Road Improvements$59,260,00013
Parking Facilities$1,800,00014
Total$1,331,510,000

The Vashon Crossing Alternative will move approximately 90,000 vehicles across central Puget Sound daily instead of 6,700 cars which will be the maximum capacity of the ferry system after spending over $1 Billion dollars to make the necessary improvements and upgrades. The Vashon Crossing Alternative eliminates the need for (and the cost associated with) the existing ferry service between Bremerton/Seattle, Southworth/Vashon and Fauntleroy resulting in the elimination of anticipated expenditures as detailed on page two (2) herein of: -$1,012,200,000

Total Vashon Crossing Capital Cost: $319,310,000

COMPARISON OF CAPITAL COST

VASHON CROSSING VS TACOMA NARROWS CROSSING

Capital cost of Tacoma Narrows Crossing including required ferry upgrades = $1,436,210,000

Capital cost of the Vashon Crossing including ferry system savings = $ 319,310,000

Resultant savings to the taxpayers if Washington State Department of Transportation selects the Vashon Crossing Alternative. $1,116,900,000

THATS RIGHT - OVER $1.1 BILLION DOLLARS SAVED

CONCLUSION:

Any "apples to apples" cost comparison must include all cost associated with reaching the same end results. In this case, all previous studies on this subject indicated a new Tacoma Narrows Bridge as a "stand alone" project does not solve the problem of adequate mobility across central Puget Sound (thus the need for including the costs of upgrading the existing ferry system into this comparative study). On the other hand, the Vashon Crossing as a "stand alone" project adds more than adequate capacity to the central Puget Sound crossing situation (thus the elimination of the existing ferry routes) yet the most optimistic prediction is that it would relieve no more than thirty (30%) percent of the existing traffic from the Tacoma Narrows Bridge. Thirty (30%) percent today, however, would bring the Tacoma Narrows Bridge under it design capacity and would solve the congestion problem but without a fixed structure across central Puget Sound there will be no way to increase vehicle capacity by even ten (10%) no matter how much money was spent.

Whichever solution is ultimately selected will require annual maintenance and operation costs over the entire life of the improvement. If we use the bonding life of fifty (50) years as the useful life of the project these costs annual will be:

TACOMA NARROWS BRIDGE MAINTENANCE/OPERATIONS COST

  • New Tacoma Narrows Bridge $ 900,00015
  • All Road/Other Improvements $ 420,00016
  • Annual Total $ 1,320,000

ADD FERRY MAINTENANCE/OPERATION COST (Required under the Tacoma Narrows Bridge Alternative)

  • Ferry Vessels $33,000,00017
  • Ferry Terminals $ 4,000,00018
  • Fixed Structures $ 900,00019
  • Transit $ 1,400,00020
  • Annual Total $39,300,000
  • Total Bridge & Ferry Annual M&O Cost $40,620,000

VASHON CROSSING MAINTENANCE/OPERATIONS COST

  • Burien/Vashon Floating Bridge: $2,500,00021
  • Fragaria/Vashon Suspension Bridge: $ 550,00022
  • All Road/Other Improvements: $1,050,00023
  • Total: $4,100,000

The difference results in a savings to taxpayers of: $36,520,000

Each and every year over the term of the bonds: x 50

Resulting in a lifetime savings to the taxpayers of: $1,826,000,000

Selecting the Vashon Crossing as the preferred alternative further eliminates the existing current costs of ferry operations at Bremerton, Southworth, Vashon & Fauntleroy resulting in additional annual savings to taxpayers of:

  • Terminal Operation Savings $15,000,00024
  • Vessel Operation Savings $73,000,00025
  • This element would save the taxpayers an additional: $88,000,000
  • Each and every year over the term of the bonds: x 50
  • Resulting in a lifetime savings of: $4,400,000,000
  • Together with the M&O savings from above: $1,826,000,000
  • Results in a total lifetime M&O savings of: $6,226,000,000
  • Now add the initial construction cost savings of: $1,116,900,000

The Vashon Crossing will save the taxpayers: $7,342,900,000. Which does not include savings on the debt service associated with this project.

With all of these facts and figures and details and numbers available to anyone who would take the time to investigate this matter, why is it that the Washington State Department of Transportation has refused to complete an "apples to apples" evaluate of the

VASHON CROSSING ALTERNATIVE?

Sincerely,

Randy Boss, Chairman

1 Part Honesty; 2 Parts Arrogance

At a March 23, 2005, House Appropriations hearing on a bill to gut the voter-approved I-601 spending limit, Rep. Jim McIntire (D) asked a supporter of I-601’s two-third supermajority requirement for the legislature to raise taxes the following question:

"Can you name a time when we [legislators] have actually not just set it [supermajority requirement] aside by majority vote? I mean, this is in many respects a procedural motion that has no bearing. It’s a statutory constraint that cannot constrain any legislature that chooses as a majority to set it aside . . . have we ever used a supermajority [to raise taxes]?"

Despite the arrogance of some state officials, Washington's constitution is clear: "All political power is inherent in the people..."
