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 South Tees Development Corporation site, the expanding port facilities along the River Tees and the newly rebranded 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. 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. 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. 1 Tees Valley Combined Authority New Tees Crossing – Outline Business Case 24 October 2019 ▪ Version 1.0 ▪ Issue 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; • 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. The base cost estimate for the preferred option is £205,284,154, whilst the estimated outturn cost is £298,317,817, with the latter figure also including a calculated allowance for risk. The costs have been derived in a robust way using information from current and recently completed projects, and the works required have been quantified based on the current scheme designs. Several potential funding routes have been considered for the scheme, with the most appropriate being the Highways England Road Investment Strategy and the Large Local Majors element of the new National Roads Fund. Irrespective of the final funding route, given its high level of interaction with the Strategic Road Network, the scheme should, ideally, be delivered by Highways England through its procurement processes and procedures allied to the Project Control Framework. On this basis, the procurement strategy that has been prepared recommends that the Late Early Contractor Involvement method of procurement be adopted for the scheme, with appointment of the contractor after publication of the draft Orders and Environmental Statement. A sound governance structure has been in place throughout the life of the scheme, and Highways England has been closely involved in its development since inception. Highways England is supportive of the scheme, and its in-house technical assurance teams have reviewed the traffic, economic and environmental products prepared in support of this business case. A project plan has been developed setting out all of the key project tasks and their duration, the interdependencies between each of the tasks, and key milestones and gateways. This plan envisages a start of works in 2024 and completion of the scheme by 2027. Finally, to support the ongoing development and implementation of the scheme, a stakeholder engagement and public consultation strategy has been created and outline benefits realisation and monitoring and evaluation plans produced.
