Motorists are advised to plan ahead before they travel in the
coming months as a series of major road works and lane closures
are set to begin on two separate sections of the M4 this summer.
The road works between junctions 47 and 49 will take place from
August to December. There will also be diversions in place
between junctions 24 and 28 on the eastern side of the Brynglas
tunnels in September.
Both projects involve essential maintenance work to ensure the
longer term resilience of the road network and to avoid any
unplanned emergency repairs. The work will involve the
re-waterproofing, resurfacing and replacement of bridge joints to
several bridge decks. Work is taking place during the summer
period to minimise the likelihood of delays to the work caused by
adverse weather conditions.
During the works between junctions 47 and 49, the traffic
management layout will change to accommodate each phase of the
scheme with traffic running in contraflow using the hard shoulder
from early September until mid-November. Lower, mandatory speed
limits will also be in place to protect drivers and the workforce
delivering the scheme.
To accommodate works between junction 24-28 a four-weekend and
eight-night work programme has been put in place involving full
carriageway closures, avoiding simultaneous closure of the
eastbound and westbound carriageway. This could be reduced to two
weekends and eight nights depending on weather conditions.
Notification of the works including times for contraflow
arrangements will be published on Traffic Wales website: Traffic Wales | Traffic
