Don't forget that the sites in Dubai and Portland are totally different - we have to rebuild what, 3+ miles of freeway, interchanges, tear down 2 existing bridges, and build a new one in the same corridor, all while rerouting traffic (not interrupting it), and prevent construction waste from falling into the river and killing salmon. The Dubai project gets built on a blank-slate site, to cross an artificial lake!
The environmental rule differences in the two countries alone would cause a huge difference in costs.
Don't forget that labor is also the largest expenditure of money. Materials count for a smaller fraction of total costs... so if the labor costs 10-20
times more in the US than Dubai... expect labor-intensive infrastructure to be expensive.

The wages of construction workers, which range from $106 to $250 per month, contrast starkly with the national average wage of $2,106 per month. Many recent workers’ protests have centered on demands for better wages. Although the UAE Labor Law of 1980 requires the government to implement a minimum wage, it has failed to do so for the past 26 years.

In 2005, the average annual wage in the construction industry was $39,897 – over $3,000 more per year than the average annual wage for all industries in Oregon.

$39,897 / 12 months = $3,324.75
Note that they
will use Union on a state project, so the wages will be higher. $3-4 grand a month is significantly higher than $100 - $200 a month.
Personally, I feel good about the fact that our workers get paid a comparatively decent wage to what everyone else gets paid. If we want good design, however, we need to pay for it... and then there's the fact that in 1 week we piss the same amount of money on the Iraq war.
