Next phase of Junction 25 works

A multi-million pound scheme to improve the busy M5 Junction 25 in Taunton will enter a new phase later this month with the start of works to widen the Toneway.

Somerset County Council is currently upgrading Junction 25 to improve traffic flow, ease peak hour congestion and unlock land for employment to the east of the M5.

The scheme started earlier this year and so far has made good progress with widening of the J25 roundabout, clearance of the old farm and access at the park and ride site all taking place at night or offline to minimise disruption.

The next step is for contractor Alun Griffiths to widen the Toneway on the approach to Junction 25 starting on Saturday 27 July.

This phase will require lane closures, narrow lanes and a reduced speed limit to keep the workforce and road users safe while work is underway.

The Toneway will be closed for four nights between 8pm and 6am while traffic management is set up. Once in place, two lanes will be kept open for traffic heading into town from Junction 25 but only one lane will be open for traffic heading out of town towards Junction 25 (see plan below).

Councillor John Woodman, Somerset County Council’s Cabinet Member for Highways, said: “This upgrade of Junction 25 is vital for Taunton and Somerset so we’re very pleased to see it progressing well, particularly with so much achieved already with minimal impact on the public.

“We now need to start widening the Toneway – a significant piece of engineering which cannot be done offline. We’re doing our best to keep traffic moving as much as possible but please do bear with us during this phase and plan your journey carefully.”

This arrangement on the Toneway is expected to remain in place until summer 2020 when works will switch elsewhere. Sign up for newsletters to stay up to date with progress and any changes.

The J25 scheme upgrade is expected to cost around £19.2m with allocated funding from the Heart of the South West Local Enterprise Partnership (LEP) Growth Deal Fund, Taunton Deane Borough Council, Highways England, Somerset County Council and developer contributions.

The Heart of the South West LEP’s total Growth Deal is worth over £590m; including £239m from Government and £351m match funding. Over the lifetime of the Growth Deal: 2015 – 2021; HotSW LEP estimates the investment will create up to 26,930 new jobs and 18,242 new homes; over 59,000 people will be trained under this programme and over 30,000 businesses will have been supported.

“Local Growth Fund”

Local Enterprise Partnerships are playing a vital role in driving forward economic growth across the country, helping to build a country that works for everyone. That’s why by 2021 Government will have invested over £12bn through the Local Growth Fund, allowing LEPs to use their local knowledge to get all areas of the country firing on all cylinders.

Some additional key facts:

  • There are 38 LEPs covering the whole of England
  • The government has awarded £9.1bn in three rounds of Growth Deals to local areas to drive economic
  • LEPs are investing in a wide range of projects including transport, skills, business support, broadband, innovation and flood
