Explosives only have to be placed on the supports and the ongoing construction would be great cover to place the explosives. Wouldn’t be able to see evidence of that, as it would be covered by the bridge. Fox reporting eyewitness accounts of explosions/things exploding.
If it was AlQueda, you would see a half dozen bridges down across the country.
If it were the Somoli residents of Minn., then you would see jumping/cheering/handing out of candy by Muslims.
Methinks it was a 40 year old (relatively new) UNION built bridge.
Hmmmmmmm
