As commuters and children travelled in to work and school this Friday (March 11), queues of traffic developed throughout Hertfordshire.

The A1081 Harpenden Road was congested between Childwickbury and St Albans.

There were approximately two miles of queuing traffic on the route into the city from Harpenden at 8am.

An alternative route, using the A5183 Redbourn Road, is currently blocked due to a road closure.

The road closure is expected to continue until March 20.

In Harlow, Essex, gas firm Cadent has set up emergency works on the A1184 Cambridge Road.

There are temporary traffic lights which have caused delays in both directions between Sawbridgeworth and the A414 at Harlow Mill railway station.

The works were put into place yesterday, and data from One Network shows that disruption could continue until Wednesday, March 16.

An earlier queue on the A41 approaching the M25 at Watford is now clear.

The A111 Stagg Hill was slow moving between the M25 junction 24 (Potters Bar) and Cockfosters London Underground station.

The congestion has since cleared.

In Welwyn Garden City, traffic on the A1000 and A6129 approaching the A1(M) and Hatfield is moving after earlier tailbacks.

On the railways, Great Northern trains between Hertfordshire and London are not stopping at Essex Road station in Canonbury.

This is due to a local power cut impacting the station.
