Residents and local businesses are due to attend a public meeting later to discuss continuing concerns over the trial closure of Junction 41, Port Talbot.
The meeting comes as the trial closure period draws to an end, but a decision as to whether it will re-open is yet to be made.
The westbound slip road has now been closed during peak times since August of last year in an effort to ease traffic problems.
