Weekend closure of the A34 & A33 on 15 & 16 November
Closure of the A34 from Three Maids Hill southbound and the A33 from the Cart and Horses junction southbound for 24 hours from 9pm on Saturday 15 November.
Published: 26 October 2025
Essential repairs have been ongoing beneath Kings Worthy Bridge, including beam strengthening and concrete removal. The next phase of this repair work involves removing the first of two bridge beams.
Due to the location of the bridge and the size of the crane that will be used, there will be a need to close the A34 from Three Maids Hill southbound and the A33 from the Cart and Horses junction southbound for 24 hours to complete the northern edge beam removal safely.
This is planned to take place from 9pm on Saturday 15 November until 9pm on Sunday 16 November 2025.
There will be a diversion in place via the A34, A303 and the M3.
Repairs to this bridge will continue throughout the course of the project. This will include re-installing the first beam and removing and re-installing the second beam. As the work progresses, further updates wll be issued.
In the event of poor weather conditions or other issues out of our control, planned work may be postponed at short notice.
