On our way back from the DIME weekend, we came round a corner on the A9 to see a line of red lights winding across the valley as far as we could see. These roadworks, to do with the construction of anew roundabout, had delayed us about 20 minutes coming north, but this queue looked much much longer.
Half the traffic seemed to be heading up a narrow road up the hillside to our left, so after looking at a map, Rachel decided to give it a go. We followed as part of a constant line of traffic down this single track road (the drivers coming the other way were pulled over and looking very bored with it all), before coming to a junction and choosing to rejoin the main road at the new roundabout, with only a short (15 minute) queue to get through the traffic lights at the contraflow.
All in all we had saved about 75 minutes, and were not far behind the bus with the kids on by the time we reached Perth.
