What we are doing
In preparation for the main construction phase of the Chipping Warden Green Tunnel, we will soon begin receiving deliveries of precast tunnel segments. The segments for the green tunnel will be built in a factory in Derbyshire and then transported to Chipping Warden so they can be assembled within the excavated tunnel trench. Once in place, the segments will be covered with earth and landscaped to blend into the surrounding countryside.
The deliveries of these tunnel segments will be classed as abnormal loads and you will see HGVs carrying these distinctive, curved concrete structures to our Chipping Warden compound.
We expect deliveries to take place Monday to Friday, with approximately 10 – 15 deliveries each day. Wherever possible, we will minimise the impact on highway users by coordinating deliveries to avoid peak times.
In order to deliver our widest segments safely, we will require a southbound carriageway closure of the A361 for approximately 2 hours on Sunday mornings from 15 May, subject to consents. The southbound lane closure is required to allow the wide loads to safely pass through the narrow sections of highway near Wardington.
We will make improvements and adjustments to this process once our initial deliveries are complete.
Construction of the tunnel is expected to be fully complete in 2024.
