Cart and Horses Junction Improvements, Winchester

Developing proposals to improve the junction

Last update: June 2024

Scheme overview

The Cart and Horses junction in Kings Worthy is a staggered priority junction located on the A33 where it intersects the B3047. In light of the proposed highway changes by National Highways at M3 Junction 9, and a strong local desire to see the junction redesigned to better accommodate vehicular movements the County Council  has developed proposals to improve the junction.

At the Cart & Horses junction initial optioneering design work has been undertaken to examine different junction options in light of the National Highways proposed changes to the A30 as part of the M3 Junction 9 project. The design options are for either a signalised junction, or two compact roundabouts. No funding has been identified to deliver a scheme, so the County Council will work with National Highways to develop a delivery and funding plan.

Before carrying out any further design and other technical work on the Cart and Horses junction options, the County Council is currently waiting for the outcome of the M3 Junction 9 Development Consent Order (DCO) to be confirmed, with a decision from the Secretary of State for Transport expected by May 2024. Information on the M3 Junction 9 project, including latest updates and expected DCO timescales, can be found on the National Highways scheme webpage; M3 junction 9 improvements - National Highways.
