The '''A66''' is a major road in [[Northern England]], which in part follows the course of the [[Roman roads in Britain|Roman road]] from [[Scotch Corner]] to [[Penrith, Cumbria|Penrith]].<ref>[[:Image:Romanbritain.jpg|Map of Roman Roads in Britain]]</ref> It runs from east of [[Middlesbrough]] in [[North Yorkshire]] to [[Workington]] in [[Cumbria]].{{cn|date=September 2025}} The road has been progressively improved with dual carriageway sections, but with stretches of single carriageway road. The road is set to be completely dualled between Scotch Corner and Penrith, with a £1.3&nbsp;billion scheme being announced in March 2024.

== Route ==
From its eastern terminus between [[Redcar]] and Middlesbrough it runs past [[Stockton-on-Tees]] and [[Darlington]] mainly as two-lane [[dual-carriageway]] and single carriageway past Darlington, becoming motorway standard as the A66(M) shortly before meeting junction 57 of the [[A1 road (Great Britain)|A1(M)]]. It shares the A1(M) route south to [[Scotch Corner]], from where it continues west across the [[Pennines]], past [[Brough, Cumbria|Brough]], [[Appleby, Westmorland|Appleby]], [[Kirkby Thore]], [[Temple Sowerby]] and [[Penrith, Cumbria|Penrith]] until it reaches Junction 40 of the [[M6 motorway]] at Skirsgill Interchange, where traffic going towards Western Scotland turns onto the northbound M6. The A66 continues past [[Blencathra]] to [[Keswick, Cumbria|Keswick]] and [[Cockermouth]] and on through the northern reaches of the [[Lake District]] before arriving at the coastal town of [[Workington]]. There is a short stretch of dual carriageway along the northern part of Bassenthwaite Lake between Keswick and Cockermouth. Whilst the eastbound section follows the straight line of the disused [[Cockermouth, Keswick and Penrith Railway]], the westbound section has numerous bends with climbs and dips. The westbound section was closed due to flood damage in December 2015; when it re-opened in May 2016, the road had been permanently reduced to a single lane. This section has a {{convert|50|mph|adj=on}} limit monitored by [[Speed camera#Average speed cameras|average speed cameras]].<ref>{{cite web |url=http://www.highways.gov.uk/news/pressrelease.aspx?pressreleaseid=410876 |title=Safety Cameras to Improve A66 Safety |publisher=Highways Agency |type=Press Release |date=2 February 2010 |access-date=1 November 2015 |archive-url=https://web.archive.org/web/20120707102843/http://www.highways.gov.uk/news/pressrelease.aspx?pressreleaseid=410876 |archive-date=7 July 2012 |url-status=dead  }}</ref>

== History ==

When road numbers were first [[Great Britain road numbering scheme|designated]] in the 1920s,<ref>{{cite web|url = http://www.thensg.org.uk/documents/Guidance%20on%20Road%20Classification%20and%20Primary%20Route%20Network.pdf|title = Guidance on Road Classification and the Primary Route Network|access-date = 1 November 2015|publisher = UK HMG|page = 3}}</ref> the A66 was assigned to the route between Penrith and [[Kingston upon Hull|Hull]] via Scotch Corner and [[York]], mainly along former [[Roman road]]s.<ref name=":1" /> Today's route largely follows the original route between Penrith and Scotch Corner. The historic route between Scotch Corner and Hull follows what is now today's [[A1 road (Great Britain)|A1]], [[A168 road|A168]], [[B6265 road|B6265]], [[A59 road (Great Britain)|A59]] and [[A1079 road|A1079]].

It is [[Anomalously numbered roads in Great Britain|anomalously numbered]] since west of [[Penrith, Cumbria|Penrith]] it trespasses into numbering zone 5; this is because it originally terminated at the [[A6 road (England)|A6]] in Penrith but was extended further west in order to create one continuous east–west route. Most of what is now the A66 west of Penrith was originally [[A594 road (Cumbria)|A594]] – only a small stub of this road numbering remains, from [[Maryport]] to [[Cockermouth]].

== Proposed developments ==

=== Trans-Pennine dualling ===

The middle {{convert|49.5|mi}} section of the A66 between [[Scotch Corner]] on the A1(M) and Penrith on the [[M6 motorway|M6]] forms one of the key trans-Pennines trunk routes and has one of the worst road-safety records in the UK. Various bypasses and upgrades have been constructed since the early 1970s, giving the current mix of single and dual-carriageway sections. In 2002, after many years of local campaigning, the Transport Minister, [[John Spellar]], gave support for the upgrading of the remaining single-carriageway sections by the [[Highways Agency]].<ref name=":0">{{cite news|title = Environment warning over road plan|url = https://news.bbc.co.uk/2/hi/uk_news/england/2211203.stm|newspaper = BBC|date = 23 August 2002|access-date = 1 November 2015}}</ref> The first three projects began construction in early 2006 and opened in 2007{{cn|date=September 2024}} and 2008. The whole route between the A1(M) and M6 was due to be dualled by 2011, by which time the upgrade of the A1 to motorway status at Scotch Corner was planned to be complete.

After the construction of several sections commenced, it was announced that those schemes currently in the planning phase would not go ahead until 2016 at the earliest. The Highways Agency website states "Other than those already committed, the Regions did not identify any other major schemes for the A66 as high priorities to receive funding. This means that there is currently no likelihood of any additional major schemes on this route being funded within the next ten-year period. However the Regional Funding Allocation process will be reviewed in due course and this will give an opportunity for the Regions to revise their priorities."{{citation needed|date=March 2019}}

In September 2015, the government said that £500,000 would be invested into the study of the two Trans-Pennine routes of the A66 and the [[A69 road|A69]]. The proposal would be for one or even both roads to be dualled wholly between the A1/A1(M) and the M6.<ref>{{cite web|title = Northern Powerhouse study to look at dualling whole of A66 and A69|url = http://www.chroniclelive.co.uk/news/north-east-news/northern-powerhouse-study-look-dualling-10059029|website = nechronicle|access-date = 1 November 2015}}</ref> The following year the government announced that the A66 would be dualled, but not the A69.<ref>{{cite news | url=http://www.chroniclelive.co.uk/news/north-east-news/plans-dual-a66-over-a69-12221294 | title=Why are plans to dual the A66 over the A69 going ahead? We look at what impact it will have | newspaper=[[Evening Chronicle]] | location=Newcastle | date=23 November 2016 | first=Michael |last=Muncaster}}</ref>  In March 2019, project director Matt Townsend from [[Highways England]] announced plans for a public consultation from May 2019, in which it would present its plans for a £500 million spend to complete dualling the Trans-Pennine section, together with improvements at the M6 and A1(M) interchanges.<ref name="2019_consultation">{{cite news | url=https://www.thenorthernecho.co.uk/news/17485227.consultation-due-to-start-in-may-on-a66-changes/ | title=Consultation due to start in May on A66 changes | newspaper=[[The Northern Echo]] | author=Graeme Hetherington  | date=7 March 2019 | access-date=8 March 2019}}</ref>

In March 2024, Transport Secretary Mark Harper approved a £1.3&nbsp;billion scheme to dual the A66 in its entirety between Scotch Corner and Penrith. Work would begin on the scheme in the latter half of 2024.<ref>{{cite news |title=A66 dual carriageway project approved by government |url=https://www.bbc.co.uk/news/uk-england-cumbria-68510758 |access-date=8 March 2024 |work=BBC News |date=8 March 2024}}</ref><ref>{{cite news |last1=Abruzzese |first1=Phoebe |title=A66 £1.3bn dual-carriageway upgrade approved by government |url=https://www.darlingtonandstocktontimes.co.uk/news/24171742.a66-dual-carriageway-upgrade-scotch-corner-penrith-approved/ |access-date=8 March 2024 |work=Darlington and Stockton Times |date=8 March 2024}}</ref>

Additionally, a plan to create a second crossing of the [[River Tees]] near Middlesbrough for traffic on the congested [[A19 road]] would see the widening of the A66 between [[Teesside Park]] and the [[Tees Viaduct]] interchange.<ref>{{cite news |title=Plans revealed to reduce crossing pressure |url=https://www.bbc.co.uk/news/uk-england-tees-47561301 |access-date=15 July 2020 |work=BBC News |date=13 March 2019}}</ref><ref>{{cite news |last1=Nolan |first1=Laura |title=£24m committed to Tees Crossing |work=Darlington & Stockton Times |issue=21–2020 |date=22 May 2020 |page=5|issn=2516-5348}}</ref>

== Safety ==
The section of road between Scotch Corner and Penrith accounted for 70 deaths over ten years up until 2002, which was above the national average for single lane carriageways.<ref name=":0" /> Whilst the number of accidents was in line with the national average, the number of serious injuries and deaths was twice the national average; this high attrition rate was the reason for the go-ahead for the new dualled sections on the grounds of safety.<ref>{{cite web|url = http://assets.highways.gov.uk/our-road-network/pope/major-schemes/A66%20Carkin%20Moor%20to%20Scotch%20Corner%20Improvement/POPE%20_%20A66%20Carkin%20Moor%20to%20Scotch%20Corner%20OYA%20report%20_%20final.pdf|title = Carkin Moor to Scotch Corner Improvement – One Year After Study|access-date = 1 November 2015|publisher = Highways Agency|page = 23|archive-url = https://web.archive.org/web/20160304100910/http://assets.highways.gov.uk/our-road-network/pope/major-schemes/A66%20Carkin%20Moor%20to%20Scotch%20Corner%20Improvement/POPE%20_%20A66%20Carkin%20Moor%20to%20Scotch%20Corner%20OYA%20report%20_%20final.pdf|archive-date = 4 March 2016|url-status = dead}}</ref>

Keith Buchan, a highly experienced transport planner, examined the safety record of the A66 and the evidence submitted during the planning examination for the £1.5&nbsp;billion A66 Northern Trans-Pennine project. In the 'Improving safety on the A66' report, he makes recommendations for safety improvements on the A66 which could be implemented now, at low cost, rather than waiting five years for the £1.5&nbsp;billion A66 scheme to be built.<ref>{{cite web |title=Improving safety on the A66 – faster, cheaper |url=https://transportactionnetwork.org.uk/improving-safety-on-the-a66-faster-cheaper/ |website=Transport Action Network|accessdate=6 June 2025}}</ref>
