Motion:
“The SR 520 Seattle replacement bridge is outrageously expensive when compared to the costs of the 1963 bridge in real terms.” 4 of 6
• Are the two projects really similar?
In your post reply you say:
The new bridge will cost = $4B
And that is made of the following pieces:
• Right of way land = $90M
• Eastside construction estimate = $306M
• Westside construction estimate = $2.3B from:
• Bridge itself then is $2.3B - $306M = $2B
You then say that the Old bridge cost $21M for whole project (bridge plus other stuff)
And using real CPI in 2012 dollars it is $161M
“So, new bridge project is 25 times as expensive as old one in inflation-adjusted dollars.”
$161,000,000.00 x 25 = $4,025,000,000.00 is how I assume you got there.
Data on the New Project: The legislative budget cap for the project was $4.65B
http://www.wsdot.wa.gov/Projects/SR520Bridge/Budget.htmFrom what I can tell, they saved some money here and there but they fear that they could eat up a lot of that savings later.
• The difference between 2010 and 2012 estimates for Floating Bridge, Pontoon and Eastside projects is primarily due to a favorable bidding environment and retired risks with completion of the environmental documents and permitting.
• The difference between 2012 and 2014 estimates for the remaining unfunded elements is primarily due to escalation and risks associated with delivering the remaining scope of work.

(I assume it was budgeted, and they are just waiting on the exact funding source. But I do not know)
Overall as of 2014 overall they looked under budget by $180M. They have the SR 520 Program Total for 2014 at coming in at $4,471 M.
I know you had the just the bridge construction number at $2B, I am not sure how you got there. At one point I thought that I had it, $2.077B.
http://www.wsdot.wa.gov/Projects/SR520Bridge/Budget.htmBut that number is not just the bridge. It includes a lot more work than just the bridge.
I looked here:
http://www.wsdot.wa.gov/NR/rdonlyres/FFB41DA9-DC53-4906-891C-C4A643ED0627/0/2015_0513_SR520ExpendituresToDate_ThruDec2014_FINAL.pdf. While it is detailed, I do not know enough about the area to go figure out what is what. My guess is if some had the patience and the local knowledge they could figure out a close enough just bridge number.
In the end I just settled on this data and said 630M+561M+696M=1,887B
http://www.wsdot.wa.gov/NR/rdonlyres/661509A0-3C1B-4A4E-9719-13EFE4A35E94/0/2015_0116_SR520_CEVP_CostMap_Final.pdfTell me, am I getting something wrong? (I really am not even sure what body of water we are actually talking about!)
So I guess 1,887B is close enough to 2B to move forward.
Data on the Old Project: You say about the old project
“[The] Old bridge…cost $21M for whole project (bridge plus other stuff) in 1961 dollars”
I am not sure I agree with you.
Go to page 4, page 11, page 13 and page 14 of the
August 1963 Bridge Opening Program. http://www.wsdot.wa.gov/NR/rdonlyres/D2751414-2ED6-435C-AE18-EDB24A7178E3/0/1963_SR520_BridgeOpening_Program.pdfOn page 11and again on page 13 the cost of the bridge is put at $22.5M (1963 $). And as you can see,
it does not include “bridge plus other stuff”. It is just the bridge. Page 14: The total construction price (which includes the construction costs of the “other stuff”) was $63.7M. When you add in the right of way the cost is $89.5M.
One big caveat, most of the line item amounts are listed as “final estimates not available – this is the contract bid price”. So I think that it would be very reasonable to expect that the actual final cost was north of that. This is all a guess, but here is one reason to accept that the final cost was probably higher.
Go to page 2 of the
Washington Highway News, July-August 1963, Volume 1 No.1. http://www.wsdot.wa.gov/projects/sr520bridge/memorylane/pdfs/WHN_7-8_1963.pdfRight at the top: so and so “…will officially open the $24,972,000 2.3 mile structure….This combination of the bridge and the freeway, which cost more than $ 80 million ….”
Two items standout, 1) The bridge is cited as 2.3 miles long, the old bridge is listed as 1.43 miles long. 2) The number 80 million is just too perfect a round a number, plus it is not clear if it is for construction + right of way. But what the heck. Any ideas? My guess is that it is construction only.
I am going to assume that the 1963 bridge cost $25M.
So where does that put us?
I think that comparing the 1963 bridge costs to the 2014 entire project costs is an error. Comparing the two at a total project level does not make much sense. There are far too many things that are just different. For example, there is no East Roanoke St to NE 104th way construction in 2014.
A 1963 bridge cost to 2014 bridge cost seems like the logical thing to do. Assume:
1963 bridge cost $25M
2014 bridge cost 1,887B or $2B
Based on your original CPI approach you would be at $192M in 2014 dollars and you might claim that the 2014 project is 10 times as expenses as the 1961 bridge in real dollars.
(192,000,000.00x10.42=2,000,000,000.00)
Or
(192,000,000.00x9.83=1,887,000,000.00)
Based on a more appropriate deflator that number would be at $717M in 2014 dollars and it would be fair to say that
the project is about 3 times as expenses as the 1961 bridge in real dollars. (717,000,000.00x2.79=2,000,000,000.00)
Or
(717,000,000.00x2.63=1,887,000,000.00)
The reason I took the time to run through CPI here was to show that if you had used a bridge to bridge comparison you would not be saying that the project is now 25 times as expensive, you might say that it is 10 times as expensive.
