Pic looks like its from the 70s judging by the cars in traffic and dudes shoes
Under the "adding a lane" is a white-ish car. those taillights look like an early eighties Buick, or an early eighties Olds Cutlass Supreme. The quad headlight wagon as mentioned before, looks to be early eighties.
No way that was taken 2008 as flickr says it was added. Too much old rice in the pic to be on the highway and not rusting in pick-a-part. And those are Nike or knock-offs, Puma's swoosh starts from the sole and goes up and back.
.I don't remember anybody wearing those wide-leg pants that far back, though.
