Roadworks to tackle ‘pinch points’ on the A1(M) near Stevenage will begin next month after delays.

The lane arrangement will be altered before and after Junction 6 for Welwyn and the northbound slip road will be increased to reduce queuing.

However no work will be undertaken to widen the road.

Instead a ‘lane-drop’ will be created by extending the slip way.

It is hoped the works will improve traffic flow and reduce congestion for northbound traffic between junctions 6 and 7 Stevenage.

Experts think this will stop queueing occurring where the road changes from three lanes to two.

The work – expected to cost around £2.2 million – was supposed to start earlier this year but has been delayed.

The first phase will take place from December 8 until 22, and the second from January 5 to March 27, 2015.

It is likely full road closures will be in place for some of the works but a schedule has yet to be finalised by the Highways Agency, which manages the motorway.

The stretch of road is used by around 39,000 vehicles everyday and each day at peak times has long tailbacks.

The widening of the A1(M) will also be discussed in the House of Commons tomorrow.

MP for North and East Hertfordshire Sir Oliver Heald has secured a debate, which will outline the issues on the road between Welwyn and Stevenage, to take place late in the afternoon.
