Drivers in Carmarthenshire are facing delays for the next week due to ’emergency repairs’ ongoing near Pont Abraham.
There has been heavy congestion on the A48 eastbound since last Wednesday, due to a lane closure on the M4 eastbound after J49 for roadworks.
Traffic Wales has confirmed that this lane closure will remain in place until Saturday, June 7, for “investigation works”. The same stretch of road was closed for a number of hours on Tuesday, May 27, after a crash, says Wales Online.
There have regularly been 20-minute queues back towards the Cross Hands roundabout on the A48 reported since the lane was shut at around 1pm on Wednesday.
A post on Traffic Wales’ social media pages said: “A48 southbound Cwmgwili – J49 Pont Abraham. Lane closures in place until 7 June for investigation works. We’re aware of concerns about lack of visible activity— assessments are ongoing to plan future maintenance. We apologise for the inconvenience.”
