– Outline Business Case 11 November 2020 ▪ Version 2.0 ▪ Issue Executive Summary This document and its supporting appendices comprise the Outline Business Case for a new strategic road crossing of the River Tees, in the approximate location of the existing A19 Tees Viaduct. As this submission clearly demonstrates, there is a strong and robust case for investment in a New Tees Crossing, therefore it is recommended that the scheme is prioritised for funding so that the many benefits that it will deliver across the Tees Valley City Region can be realised as soon as possible. In particular, the scheme will: • Relieve the existing A19/A66 bottleneck, enhancing the reliability of people’s journeys across the Tees Valley’s road network and reducing the cost to the local and national economy due to congestion and delays; • Reduce journey times for local people – most drivers are expected to save more than two minutes of travel time during peak periods – unlocking development potential in the City Region through the provision of additional road capacity and making the Tees Valley more attractive to inward investors and visitors; • Improve the resilience of the network and therefore reduce the negative impact of events such as roadworks and road traffic accidents; • Make journeys safer by improving the standard and capacity of the road network; • Improve access to the Tees Valley’s Enterprise Zone sites, the Teesworks site, the expanding port facilities along the River Tees (where there is an aspirations for a freeport) and Teesside International Airport; • Deliver connectivity and journey time reliability enhancements for freight and logistics traffic – a key component of the Tees Valley’s growth plans; • Support the economic growth objectives of the Northern Powerhouse and the Tees Valley City Region; and • Help realise the full benefit of the committed A19 Norton to Wynyard improvement scheme, which is due for completion by 2022/23. The preferred option – the A19 Tees Viaduct Capacity Enhancement Option – has been identified as the one that will achieve the agreed objectives and provide a holistic solution to the identified national, regional and local issues identified. 1 Tees Valley Combined Authority New Tees Crossing – Outline Business Case 11 November 2020 ▪ Version 2.0 ▪ Issue In summary, the preferred option for the A19 New Tees Crossing will provide localised widening of the existing viaduct structure to provide three southbound lanes throughout the length of the existing Tees Viaduct between the A1046 and A66 intersections. In addition, it will also provide a new bridge structure to carry local northbound traffic, to the west of the existing Tees Viaduct structure. The economic analysis of the preferred option demonstrates that an adjusted benefit : cost ratio of over 1.5 is generated if wider economic impacts are considered, representing Medium value for money. However, it is important to note that the overall value for money of the scheme encompasses more than just the benefit : cost ratio value – there are a range of benefits for which the standard approach does not provide a monetisation methodology, or for which the calculation is outside of the current scope of assessment. These benefits are more strategic in nature, and include: • Unlocking future development growth across the City Region through the provision of additional road capacity (although not specific developments are dependent on the scheme); • Increased network resilience through the provision of additional lanes across the River Tees and the removal of existing vehicle conflicts; and • Reducing the negative impact of the ongoing and significant maintenance requirements associated with the existing Tees Viaduct and Newport Bridge structures. A cost estimate for the preferred option has been developed by Highways England including a calculated allowance for risk assuming they take the lead in scheme delivery from this point forward. This outturn cost is £468,573,365, which also includes a further allowance for portfolio risk. Excluding portfolio risk, this figure is £426,592,574. Several potential funding routes have been considered for the scheme, with Department for Transport considering the most appropriate to be the Large Local Major schemes element of the new National Roads Fund, with a contribution from TVCA. TVCA is proposing to contribute £21.33 million (5% of the Highways England cost estimate excluding portfolio risk, as would be the case with a scheme not on the Strategic Road Network) from its own resources to the scheme, having already provided a significant contribution to the development costs alongside Government funding.
