M12 at Ballinacor, Portadown This photograph was taken from the Charlestown Road bridge looking northeast towards, possibly, the only 'roundabout' on a motorway in the British Isles. Note the Traffic Calming Strips to alert motorists to slow down for the roundabout ahead. The construction of this 'roundabout' saved the Government some 2-3 million pounds in alternative construction methods. Concern at such a construction on a motorway did result in some spectecular spills from large vehicles negotiationg the roundabout. Thankfully no one has been badly injured and re-adjustments to the camber of the road has proved successful so far.
