A month ago:

"U.S. Marine jets Tuesday attacked two bridges across the Euphrates River near the Syrian border to prevent insurgents from moving foreign fighters and munitions toward Baghdad and other cities, the U.S. command said. ... A Marine statement said F/A-18 jets dropped bombs shortly after midnight on two light bridges near Karabilah, about 185 miles west of Baghdad."

Now, they have bombed eight more bridges there:

"US-led forces have bombed eight bridges on the Euphrates River in western Iraq to stop insurgents using them, US military spokesperson Major General Rick Lynch said Thursday.

"We have been taking out portions of bridges with precision strikes," he told a news conference.Of 12 bridges between the Syrian border and Ramadi, 110km west Baghdad, "four remain under control of the coalition forces and Iraqi forces after precision strikes on the others," he said. ... "We took out portions of these bridges to deny terrorists, foreign fighters and insurgents the capability to cross north to south or south to north across the Euphrates River."

However, the Iraqi Resistance report that some of these bridges are 'restructured' for use within days. That is why the Americans hit them repeatedly, as in the above case. Hence, one would expect further 'precision stikes' against these same bridges soon.

It would be appropriate here recalling Riverbend's early take on "rebuilding" Iraq's bridges:

"One of my cousins works in a prominent engineering company in Baghdad- we’ll call the company H. This company is well-known for designing and building bridges all over Iraq. My cousin, a structural engineer, is a bridge freak. He spends hours talking about pillars and trusses and steel structures to anyone who’ll listen.

As May was drawing to a close, his manager told him that someone from the CPA wanted the company to estimate the building costs of replacing the New Diyala Bridge on the South East end of Baghdad. He got his team together, they went out and assessed the damage, decided it wasn’t too extensive, but it would be costly. They did the necessary tests and analyses (mumblings about soil composition and water depth, expansion joints and girders) and came up with a number they tentatively put forward- $300,000. This included new plans and designs, raw materials (quite cheap in Iraq), labor, contractors, travel expenses, etc.

Let’s pretend my cousin is a dolt. Let’s pretend he hasn’t been working with bridges for over 17 years. Let’s pretend he didn’t work on replacing at least 20 of the 133 bridges damaged during the first Gulf War. Let’s pretend he’s wrong and the cost of rebuilding this bridge is four times the number they estimated- let’s pretend it will actually cost $1,200,000. Let’s just use our imagination.

A week later, the New Diyala Bridge contract was given to an American company. This particular company estimated the cost of rebuilding the bridge would be around- brace yourselves- $50,000,000 !!"
