speed runat 8km
if you haven't seen any coppers yet, you could open it up for about a mile and a half... no more housing, good surface, and fast sweepers
the tunnel is one way at a time and has lights on either side which run on a 5 minute cycle. try to get in front of all the cars. then when the light turns green, say a prayer that the tunnel is empty and gun it! feel the hairs rising on your arms as you crest the decline at the top of the tunnel away and downwards surrounded by flashing walls and a blast of sound behind you. ..
tunnel exitat 11km
half a mile later!!!
