Another HL2 Stuck thread.... End of highway 17?

[Seeruk]

I'm towards the end(?) of highway 17 and the freakin huge bridge. I have got all the way across, killed everything including the gunship and have no idea how to progress? Seems like a dead end - stuck just below the bridge unable to get on top of it, seems like no way to get onto the land on the other side of the bridge.. have taken to firing cabinets off the side to watch them splash in sheer frustration ararrrrrrgggg HELP!

You go under the bridge till you get to the very end (still underneath). You'll be climbing on broken catwalks and girders. On the other side you go inside a some rooms built into the bridge's support pylon, up in there is a computer where you flip a switch. Then go all the way back to the start of the bridge, and drive your buggy over the top.
