A bypass that has been promised, delayed, reviewed and re-promised for more than half a century has found a new use — as ammunition in a Senedd election row between a Green Party candidate and the Labour MS whose seat he is now trying to win.
The flashpoint came when Cllr Rob James, the Green Party’s lead candidate for Sir Gaerfyrddin — the constituency covering the whole of Carmarthenshire — posted on Facebook backing the long-awaited Llandeilo bypass.
The bypass has been in the pipeline since it was first raised in Parliament in 1970. Feasibility studies were underway by 1973. Construction was supposed to begin in 2019. It didn’t. A new start date of 2025 was set. That didn’t happen either. The current estimate has construction beginning in 2029, with completion targeted for 2031 — and a price tag of £88 million, up from an original budget of £50 million.
Cllr James invoked the case of Ella Kissi-Debrah — the first person in the UK whose death was officially linked to air pollution — to make his case. “Air quality isn’t an abstract issue. It has real consequences,” he wrote, arguing that HGVs thundering through Llandeilo’s narrow streets every day were creating real health risks.
Llandeilo is a designated air quality management area due to historic breaches in nitrogen dioxide levels. “Doing nothing,” Cllr James said, “isn’t a Green option.”
Lee Waters, the outgoing Labour MS for Llanelli — whose constituency has been absorbed into the new county-wide Sir Gaerfyrddin seat at this election — was unimpressed. A champion of sustainable transport who is not seeking re-election in May, his response on Facebook was brief and pointed: “Novel to have a Green candidate who favours building a by-pass on a flood plain.”
Waters then contacted media outlets to pile on further, saying: “See this Facebook comment from the lead Green candidate in Carmarthenshire, doubling down in favour of a by-pass. Needless to say, this is not Green policy.”
There is some irony in Waters taking this particular stand. As transport minister, he oversaw a review that froze most new road-building projects in Wales — but the Llandeilo bypass was one of the few schemes that survived the cull. A consultant, Arcadis, was subsequently appointed to develop the outline design. The bypass remains Welsh Government policy — a point Cllr James was quick to make.
“The Welsh Government has decided to take forward the Llandeilo bypass, so it’s Labour Party policy,” Cllr James hit back. “Obviously there are concerns about its precise routing and there’s a need to make sure that environmental factors are taken into consideration. To be fair, Plaid Cymru, which controls the county council, has taken that view for a long time. Llandeilo deserves its bypass.”
While the two traded blows online, Carl Peters-Bond, an independent candidate for Sir Gaerfyrddin, said the whole row was missing the point. “Having listened to the people of Llandeilo, they’re not interested in political spats — they just want their bypass built,” he said.
Peters-Bond, who has been campaigning in the town, said the reality on the ground was hard to ignore. “Whilst campaigning recently in Llandeilo it was not possible to hold a conversation for more than a few seconds before getting deafened by huge HGVs thundering through the narrow streets. Air pollution, noise and road safety concerns in Llandeilo are a real concern for residents.”
He added: “The bypass has been talked about at length for decades. It’s a trunk-route part of the major A483 that links South West and North Wales. The volume of heavy goods and other vehicle traffic that navigate the narrow roads have far exceeded what is safe. It’s about time the bypass was built.”
Cllr James also used the exchange to make a bold claim about the Greens’ prospects in the constituency. “The Labour vote in Carmarthenshire has collapsed and we believe the Greens are likely to poll higher than Labour. We are definitely in with a chance of winning a seat here,” he said.
The spat is not without its backstory. Cllr James was previously the leader of the opposition Labour group on Carmarthenshire County Council before being suspended by the party in January 2024 and subsequently joining the Greens.
His path out of Labour followed an incident in which he was accused of sending a text message to a Plaid Cymru councillor suggesting they could have some fun by claiming that Waters had two homes in Llanelli and didn’t live in either of them. He said the message was meant facetiously and that he had forgotten sending it. Party officials said allowing him to remain in Labour’s parliamentary candidate selection process would risk reputational damage for the party.
That history between the two makes the Facebook spat feel like rather more than an abstract policy debate — and all the while, in Llandeilo, the lorries keep coming through.
