The A64 Hopgrove scheme is a study Road Investment Strategy (RIS1) outlining into the improvement of the A64 Hopgrove the long term programme for England’s junction (consisting of the Hopgrove motorways and major roads for the period Roundabout and Malton Road Roundabout) of 2015 to 2020. Within this announcement, connecting the A1237 ring road and A64 the A64 Hopgrove junction was identified as near York. This includes consideration into one of 15 schemes to be developed within the potential upgrade of the A64 between this period for delivery in the following period, Hopgrove and Barton-le-Willows. 2020 to 2025 (RIS2). The RIS stated A64 Hopgrove junction – upgrading the Hopgrove 2.2.

The approach from the south/west is dual carriageway linking back 1.2. The work undertaken so far in addressing to the A1 (M) and the route north/east of the RIS requirements for the A64 Hopgrove the roundabout comprises a short length of junction comprises a feasibility study and this dual carriageway (approx. 500m) which then summary document outlines; the study’s aims merges into single carriageway (Figure 1). and objectives; the current and likely future The single carriageway continues to Barton problems along the route; the development -le-Willows (approx. 9.5 km) where a switch and assessment of potential options; and the to dual carriageway occurs. assessment of business cases for prioritised investment options.

The work on the scheme to date has Establish the case for a grade separated comprised of a feasibility study, the junction improvement (flyover or objectives of which were to: underpass) to meet the RIS requirement Develop potential solution options and Demonstrate a strategic business case assess the ability of these options to: for further progression of an improvement scheme for the route Relieve congestion on the A64 in the Hopgrove area 3.2. In terms of geographic scope, the study Improve capacity and journey time considered the length of the A64 from reliability at Hopgrove junction to Hopgrove Roundabout to Barton-le-Willows meet current and future demand where, at present, the single carriageway Improve safety on the A64 in the returns to dual carriageway (Figure 2). study area Support regeneration, economic 3.3. The study took place from spring 2016 development and the regional to spring 2017 and was undertaken by economy Highways England and its consultants.

Current and Future Situation 4.1. The first part of the study reviewed evidence vehicles per hour which occurs mainly from other relevant study work and analysis at weekends and during holiday periods. to form an understanding of the nature and scale of current and future performance on The number of accidents and the the A64 Hopgrove junction. casualties generated by these accidents are more than double the national 4.2. Analysis of traffic data suggested that there averages on the existing dual and single are a number of problems and issues on carriageway sections studied. At the the A64 that impact upon the efficient and Hopgrove junction itself accident rates safe movement of people and goods. These are approximately 30% lower than problems are likely to be exacerbated in the national average, whilst casualty rates future as a result of forecast traffic growth are in line with national average rates. on the route. 4.5. There are numerous planned residential, 4.3. The stakeholder engagement undertaken commercial and industrial land during the feasibility study comprised of developments in the proximity of the A64 initial meetings to present the study and seek Hopgrove scheme which will increase the input on requirements/constraints. These pressure on the A64 and the junction further discussions took place with the affected exacerbating the congestion and delays local highway authorities (City of York Council currently seen at the junction. and North Yorkshire County Council) and MPs whose constituencies are directly 4.6.

There was strong support for a dual traffic will grow by up to 28% by 2035 due carriageway option and concern that to both increased population within the area a junction improvement alone will not deliver from developments and due to increased the journey time benefits commuters and car usage. businesses require. 4.7. The single carriageway section of the route 4.4. Through the study process, the problems between Hopgrove and Barton-le-Willows and issues along the route were identified as: is currently at its operational capacity during identified peak periods (weekends and holiday The single carriageway section of the periods), and additional traffic could not be route is significantly stressed and is accommodated during these times.

The delays that are observed on the approaches to the junction can be attributed to the blocking back from the merge from dual to single carriageway on the A64 approximately 500m north east of the Hopgrove junction. The congestion starts to build when traffic flows exceed 1000 4 5. Investment Options 5.1. As part of the development of options, the lengths and thus different levels of capital cost, study sought to identify potentially viable traffic improvement and environmental impact. designs to demonstrate the business case for further scheme development. A four-stage 5.5. Four dualling options and two junction process was followed: options were progressed for more detailed assessment as they met all of the sifting Generation of conceptual options in a criteria of the EAST tool.

Both junction schemes relating to England, Early Assessment and Sifting development of the roundabout alone fail Tool (EAST) to address the aims to improve congestion, safety and resilience on this corridor. Despite Further development of these preferred this, given the preliminary nature of the options to provide increased detail for modelling exercise and the time savings economic assessment and commercial generated when tested with certain traffic estimation conditions on the A64, they are considered worthy of further assessment. 5.2. A wide range of options was generated and subsequently consolidated into 13 conceptual 5.7. Dualling options A, C and D all address the dualling options and five conceptual junction main source of congestion on the route (i.e. options. Additionally four junction options the single carriageway section of the A64), generated by previous work were also taken and would therefore address the scheme into consideration. objectives and support wider regional and local policy. The options generate significant 5.3. The five junction options consisted of both journey time savings but have potential at-grade and grade-separated solutions, for slightly adverse impacts on noise and and had varying capital cost, traffic and air quality, and moderate to large adverse environmental impacts.
