They will affect parts of the city centre’s waterfront on Saturday, August 6, and a wider expanse of the city’s seafront and Gower, including the A4118 and B4271 roads, on Sunday, August 7.
Thousands of leaflets, including route maps and road closure schedules, have been mailed to local householders by organisers of the Volvo 2022 World Triathlon Para Series event (Aug 6) and the following day’s IRONMAN 70.3 Swansea.
The August 6 road changes are mainly around the SA1 Waterfront, the Marina and Oystermouth Road as far west as the Victoria Park.
The Sunday changes include these areas and are extended to roads in communities such as Mumbles, Langland, Bishopston, Parkmill, Nicholaston, Knelston, Llanmadoc, Llanrhidian, Reynoldston and Mayals. Many are largely morning-only.
Emergency access will be maintained at all times.
Both events will give local residents and visitors the chance to watch – and take part in – top-class sport. They will shine a global spotlight on Swansea as thousands of athletes – some world-class – will take part over the two days.
