TRAFFIC is building on the M4 this morning after an incident near Newport.

A collision was reported near the Coldra junction (J24) of the M4.

It has since been cleared but traffic is still slow moving through to J28 Tredegar Park both directions.

Traffic is also building West of J28 in both direction - this is thought to be usual morning traffic build up.

But it's also likely that a crash on the A48 at St Mellons in contributing to M4 traffic.

An entry ramp has been closed on the A48 Eastern Avenue Westbound at A48(M) since 5am. The B4487 Newport Road is also affected from Cypress Drive roundabout heading towards the Avenue Retail Park.
