A46 to be closed between 8pm Friday 11th April - 6am Thursday 1st May

From HS2:
The work we are doing
We will be pushing a new box structure to take the HS2 line under the A46 near Kenilworth. Once the box is slid into place, we will complete the remaining works; resurface the carriageway, reinstate the white lines and safety barriers ready to reopen the A46. While we deliver the works there will be increased construction activity, 24/7 operation, overnight lighting and some additional noise. We will minimise the impact on residents as much as possible.
When the work will take place
To ensure the safety of our workforce, we will be closing a section of the A46 from the Stivichall Interchange (Festival Island) to the Thickthorn Island (A452 for Leamington and Kenilworth) for 19 days: we will hold three days as a contingency in case of an unforeseen event:
8pm Friday 11 April until 6am Thursday 1 May 2025
Afterwards there will be lane closures on the north and southbound carriageways with a speed restriction of 50mph until Thursday 31 July.
In the event of a programme delay we have a contingency window booked for 8pm Friday 16 May to 6am Thursday 5 June.
What to expect
A fully signposted strategic diversion for HGVs in the region and a local diversion as well as special access arrangements for the villages of Stoneleigh and Ashow, please see the maps on the next pages. Join us for a community drop-in event at the Kenilworth Centre on Monday 17 March between 2pm and 7pm to find out more about the A46.
