M4 bottleneck near Brynglas tunnels solutions on show

The M4 around Newport is a well-known traffic hotspot

Three exhibitions are being held to give more information about proposals to tackle congestion on the M4 between Castleton and Magor in south Wales.

New tunnels are an option in the Welsh government consultation.

Other options include a new dual carriageway to the south of Newport and junction improvements on the A48 southern distributor road.

The first exhibition is at Brynglas House, Newport, on Friday (12:00-19:00 BST).

The other two will be held on Tuesday, 15 May at the Ebenezer Baptist Church, Magor, and Thursday 17 May at the Newport Centre, both also 12:00-19:00 BST.

Transport Minister Carl Sargeant said: "Congestion on the M4 is a big concern for both the residents of Newport and for those that use this route on a daily basis."

"We are already undertaking a number of measures to address this issue but there is a clear demand for a long term solution to this matter."

Last summer, traffic was closed in both directions, causing long delays, when a lorry caught fire inside one of the Brynglas tunnels.
