Investing in your roads

At National Highways, we engineer the future to keep people moving today and better-connected tomorrow which is why we strive to improve our major roads and motorways, making sure all our roads are more dependable, durable and, most importantly, safe. 

We believe in a connected country where our network makes these connections happen. Our roads link with railway stations, ports, and airports to give people a choice of travel and to support interconnectivity. When it comes to getting people where they need to be, we provide three times more miles per person than the railways.

About us

We operate, maintain, and improve England’s motorways and major A-roads and our network totals around 4,300 miles. While this represents only 2% of all roads in England by length, these roads carry a third of all traffic by mileage and two-thirds of all heavy goods traffic. Our road network forms the economic back bone of the country, is open 24 hours a day, seven days a week and is relied on by communities and businesses to get from A to B.

Yorkshire North East: connectivity without congestion

A 670-mile network of motorways and A roads sits at the heart of the transport network in Yorkshire and the North East and provides access to international gateways – from ports at Grimsby and Immingham and Tees and Hartlepool, to airports at Teesside and Leeds-Bradford, our road system in Yorkshire and the North East supports business growth. 

From the city roads of Leeds and Newcastle to rural single carriageways, we keep our region moving. Every year, our network brings tourism to our stunning natural, cultural and historic attractions and connects the millions of holidaymakers who travel across the country to discover some of our hotspots like the Yorkshire Dales National Park and Northumberland’s picture-perfect castle-lined coastline.

The counties of South Yorkshire, West Yorkshire, North Yorkshire and East Riding of Yorkshire all have their own delights to offer, including, York, Scarborough and Beverley whilst further north, motorists can discover majestic Durham and its famous Cathedral and the cosmopolitan yet historic Tyne and Wear. No matter what type of travel our customers embark on, the Strategic Road Network in Yorkshire and the North East is one of the most diverse areas of motorways and major A-roads in the country to maintain and keep moving, so that we all get home safe and well, every day.

Why your views matter

M621 Junctions 1-7

The M621 J1-7 scheme was confirmed in the Government’s first Roads Investment Strategy (RIS1) in 2014, with construction commencing in August 2022. It is a critical part of the RIS1 investment on our network and anticipates improving journeys between Leeds city centre and the surrounding road network, which is great news for the local and regional economy.

Why the scheme is needed

An urban motorway which runs from junction 27 of the M62 to junction 43 of the M1, the M621 is a vital link between Leeds city centre and the surrounding road network. With economic growth expected in the region in the future, the Government announced proposals to provide more reliable and improved journey times for people using the M621 between junctions 1 and 7 as part of their RIS1 and aims to meet the following objectives:

  • Increase capacity and improve journey time reliability
  • Improve the safety on the route for road users
  • Provide better and real time information to road users
  • Avoid potential environmental impacts of the scheme and enhance, where possible, the natural environment
  • Support Leeds City Council's development plans to improve the transport network in Leeds 

Getting to this stage: what are we proposing?

As part of the M621 J1-7 scheme, National Highways has reviewed the speed limits along the M621 motorway. As a result, we are proposing to change the speed limits on certain entry and exit slip roads between junctions 1 to 7 of the M621. This will ensure that appropriate speed limits are in place on all slip roads. We are also proposing to make permanent the current temporary 50mph speed limit in the eastbound direction between junctions 6 and 7.

In addition, average speed enforcement cameras between junctions 1 and 5 will be installed as part of the scheme and the proposed changes are required to facilitate this upgrade.

What we’re consulting you on

National Highways and the M621 Junctions 1-7 scheme is now consulting interested parties to comment on our proposal to:

  • amend the speed limits on entry and exit slip roads between junctions 1 to 7 on the M621 motorway in Leeds,
  • extend the 50mph speed limit on the M621 eastbound from junction 6 to junction 7.

The proposed amendments will support National Highways in making a new Statutory Instrument. This statutory instrument will amend the M621 Motorway (Speed Limit) Regulations 2000 (SI 2000 No 1811), which (alongside the M621 Motorway (Speed Limit) (Amendment) Regulations 2007 (SI 2007 No 349), govern speed limits on the M621 motorway between junctions 1 and 7.

More Information: Statutory Instruments

A Statutory Instrument is the most common form of secondary (or delegated) legislation. The power to make a Statutory Instrument is set out in an Act of Parliament and usually conferred on a Minister. The Minister can then make law on matters identified in the Act, using the Parliamentary procedure set out in the Act. For more information relating to Statutory Instruments, please visit https://www.parliament.uk/about/how/laws/secondary-legislation/statutory-instruments-commons/.

Why your views matter

This Statutory Instrument consultation concerns National Highways proposed amendments to speed limits on slip roads on the M621 motorway between junctions 1 to 7, and our proposal to make permanent the temporary 50mph speed limit on the M621 eastbound from junction 6 to junction 7.

These changes are required as part of the M621 Junctions 1 to 7 Improvement Scheme. The speed limit changes will improve road safety by ensuring that appropriate limits are in place on all slip roads. They will also facilitate the installation of speed camera enforcement measures.
