On Monday the 6th of June 2016 the Cork City Marathon travelled through the Jack Lynch Tunnel and was a great success, this required a full closure of the northbound bore and the southbound bore in contraflow to allow the runners to pass through the tunnel safely. Fitzpatricks Recovery and Traffic Management Ireland started the traffic management at 04:30am in conjunction with the Gardaí closing off various slip roads and putting diversions in place.
This year due to the international licence the marathon course required a complete re-measurement. The measuring is done on a calibrated bicycle, cycling the route and taking the shortest possible line, with the assistance of the Gardaí.
The tunnel was fully reopened at 11:27am after the last of the marathon runners passed through.
