For most drivers, junction 48 in Hendy means they have almost reached the end of the M4 motorway.
But for residents living in the Carmarthenshire village and commuters who use the junction every day the area is better known for causing dangerous tailbacks on the M4, heavy traffic through the village, and a risk of accidents.
After 30 years of campaigning from local residents, however, the Welsh Government has announced a £2.5m investment to improve the area.
Work on the junction will aim to speed up journey times, boost reliability for bus services, and make it safer.
Drivers have said one of the most dangerous aspects of the area is the long tailbacks from the junction onto the M4, with many commuters heading to Llanelli having to queue on the hard shoulder.
Many have expressed their concern on social media.
"It is terrifying waiting on the hard shoulder as traffic whizzes past, especially in the dark. A major accident waiting to happen," said Kath John.
Keith Taylor added: "Waiting on that hard shoulder trying on the bridge to get to the junction in the dark with cars doing 70 miles an hour next to you is downright terrifying."
Along with the tailbacks, another problem residents have often complained about is the 'blind' junction from the Tal y Coed housing estate.
The new funding aims to improve both issues with a scheme that includes a traffic signal control for the Tal y Coed junction and a shared use path through the junction.
The Welsh Government has also said that the improvements will directly result in improved journey reliability for bus services and encourage more people to use public transport, namely the X11 service from Carmarthen to Swansea .
Discussions between the Welsh Government and Carmarthenshire Council about the work are ongoing and it's not known when work will begin. There is expected to be some disruption when preparations start, however.
If you're in a jam:
Stephen Pilliner, head of transport and engineering for Carmarthenshire Council, said: "As an authority, we have previously raised concerns over traffic entering and exiting the M4 at this junction and have lobbied Welsh Government in that respect.
"We are pleased that an improvement scheme is being taken forward, and we will continue to meet with officials regarding delivery of the proposed scheme."
A Welsh Government spokesperson added: “The funding for the M4 Hendy junction will address road safety issues, tackle congestion and improve active travel. The present traffic conditions are causing problems on both the motorway and the local road network.
“We have worked closely with Carmarthenshire Council to develop the scheme and discussions are ongoing to deliver the improvements.”
