Nice photo-shop work - - is that a 68 Pontiac GTO, those w. Holley quad, headers & custom dual were a blast to drive. Reminded me of my 78 Pontiac V8 - drove like a tank & it fly ... WS Patrol won't be happy with this, however.
Watching live traffic cam now for I-5 @ College Way, closest ones to the collapsed bridge - it's backing up with the evening/weekend getaway rush ... http://www.wsdot.com/traffic/Cameras....aspx?cam=1316

Using Google Maps to plot it - the recommended detour will take 33 miles out of the way at 1 hour 5 min. going north and 16.5 miles at 25 min. coming south - it's a 2 lane country road with a narrow shoulder, not sure how many would be happy driving in the dark on them with headlights coming almost straight at you.
