Traffic Regulation Order (TRO)

The Traffic Regulation Order (TRO) notice is the next step in the delivery of our implementation plan for the infrastructure at Kings Barton, and the future integration of the development with existing neighbourhoods and the city centre. Planning approval for these works was granted in 2012 as part of the masterplan for Kings Barton.

We have worked closely with Hampshire County Council, acting as the Highway Authority, to ensure the plans meet the required standards, and the needs of all road users, pedestrians and cyclists. Cala's priority is to deliver a modern, safe and sustainable solution for Winchester, and we’re committed to keeping the community updated throughout the future programme of works to support journey planning.

These works will deliver a new green gateway to the city along the existing Andover Road, creating a new pedestrian and cycle-friendly corridor. Upgrades to Winchester Avenue will unlock the full potential of the new neighbourhood centre and amenities at Kings Barton, including retail units, sports facilities and new Park & Ride.

The estimated start date is January 2027 for works to start on the highway with for the initial diversion of Andover Road through Winchester Avenue later in that year (2027). Preparatory works have already started to upgrade Winchester Avenue including drainage improvements, new streetlights, speed ramps, pedestrian crossings, and road surfacing.

What is a Traffic Regulation Order?

A Traffic Regulation Order (TRO) is a legal document that allows a local highway authority to manage public roads. The TROs in relation to this scheme outline proposed speed limits, parking controls and prohibition of driving. These orders are necessary to implement changes to the highway network. 

Why has Cala submitted a TRO?

Cala is responsible for the delivery of the Kings Barton development and planned off-site infrastructure, including the future diversion of Andover Road. Planning permission for these works was granted in 2012 as part of the masterplan for Kings Barton.

What happens next?

In line with the process Cala has submitted the TROs to Hampshire County Council acting as highways authority to progress. The advertised consultation period will run for 21 days from 7th November 2025, following which a decision is made on the TRO. The next steps would be for Cala to secure the relevant road space permits, technical approvals and legal agreements for the implementation.

When will works start?

We’re unable to confirm exact dates until the TRO process is complete and relevant permits are secured. If the TRO is approved, we’re working to estimated dates of January 2027 for works to start on the highway, with the initial diversion of Andover Road through Winchester Avenue later in that year (2027).
