Road users are advised a new lane on the eastbound carriageway on the A14 between Histon to Girton is now open.
Highways Agency Project Manager, Mark Saunders, said:
We have worked hard over the past 24 hours to try and get the additional lanes open to traffic in time for Easter.
The A14 eastbound between Histon and Girton opened to traffic at about 6.30am this morning with a 50mph speed limit in place due to safety reasons.
The westbound carriageway is in the final stages of construction and we aim to open westbound at the end of next week.
To help people making journeys over the Easter bank holiday, we will suspend work between Thursday 2 April and 7 April.
The scheme will be finished by early June.
Opening the extra lanes is an important step in finishing work on this project, and drivers should notice a difference to their journeys now the eastbound carriageway is open.
Other work will continue until early June, which will include street lighting work – for which a 50mph limit will be in place – and fully resurfacing the road between junctions 31 and 32, which we’ve added to the programme and will be completed using overnight closures.
Some finishing off works and landscaping means scheme completion could be early in June.
