This builds on the major scheme pro forma submitted to the North East Local Enterprise Partnership in March 2014, as part of the Strategic Economic Plan. This business case has been compiled in line with Department for Transport WebTAG guidance and the North East Local Transport Board Assurance Framework. This MSBC includes the following five cases: Strategic; Economic; Financial; Commercial; Management. 1.2 Background On 7th July 2014, the Government announced a series of Local Growth Deals. The North East was included in these deals with Government’s commitment to deliver the objectives of the North East Strategic Economic Plan (SEP), submitted in March 2014. Including additional funds awarded in January 2015, the Government is investing a total of £329.9 million in the North East Growth Deal1. The Plan aims to provide ‘more and better jobs’, with funding allocated to schemes that stimulate economic growth, as set out in the Plan. In order to ensure schemes contribute to the vision and objectives of the SEP, whilst also demonstrating value for money for the use of public funds, partners in the North East Combined Authority promoting schemes, are required to submit business cases to access capital from the fund. The Lindisfarne corridor scheme is one of a number of proposed transport schemes in the SEP, which was earmarked for early delivery in the Plan. An improvement at the A19 / A194 junction has been a long- standing priority for South Tyneside Council, as it will bring significant benefits to the Borough and the North East LEP area in terms of journey time savings, reliability, reduced congestion, and improved air quality. The highway improvement scheme at the Lindisfarne corridor was described in the Plan as providing improved connectivity to the Port of Tyne and South Shields town centre, as well as improving access to the Strategic Highway Network2. It will improve access to key, existing and new, employment and housing sites, thus, supporting much needed economic growth and job creation. 1.3 The Proposal The Lindisfarne A19 / A194 and John Reid Road A194 / A1300 roundabouts are two of the most strategically important roundabouts in South Tyneside. Between them, they provide crucial access between South Tyneside and the Port of Tyne, Sunderland, Newcastle, and Gateshead. The Lindisfarne corridor also enables access between South Tyneside and the strategic road network; to the north via the A19 / New Tyne Crossing; and to the south via the A19, A194(M) and A1(M). Traffic flows through both roundabouts are high, particularly in the morning and afternoon peak periods, which frequently results in congestion and unreliable journey times. In spells of heavy rain, Lindisfarne roundabout is prone to severe flooding which makes the roundabout impassable to all vehicles. This causes major disruption to all road users, including long distance journeys, local commuter flows, and strategic freight. When flooded, access to South Tyneside and the Port of Tyne is severed, with traffic diverted onto inappropriate roads of insufficient capacity. This has negative 1 North east Growth Deal, January 2015. http://nelep.co.uk/wp-content/uploads/2015/01/North-East-Growth-Deal-January-2015.pdf 2 More and Better Jobs; A Strategic Economic Plan for the North East, NELEP, March 2014 6 consequences for the local and regional economy. The proposed scheme is therefore expected to alleviate the risk of flooding and loss to the economic output of the area. A number of options have been considered for the corridor to alleviate current and future congestion issues. The South Tyneside VISSIM model has been used to appraise these options to identify a scheme that provides the greatest benefits in terms of journey time savings and also demonstrates a value for money solution. The proposed scheme comprises nine highway capacity enhancements in the Lindisfarne corridor to alleviate pressure on both the local and strategic highway networks, plus drainage enhancements. The principle improvements to be delivered by the scheme are, as follows: An additional lane to be provided on the A194 Leam Lane westbound approach to Lindisfarne roundabout with 295m of capacity; Widening of the A19 northbound on-slip exit to two lanes; An additional left turn lane to the A194 Leam Lane westbound approach to Lindisfarne roundabout. An additional lane is to be provided on A194 Leam Lane eastbound between Lindisfarne and John Reid Road roundabouts; An additional right turn lane is to be provided on John Reid Road roundabout circulatory to provide additional stacking capacity for right turn movements into John Reid Road; Widening of the A19 / A194 Lindisfarne roundabout to 3 lanes to provide 2 through lanes, providing stacking storage for traffic heading to the A19 northbound towards the New Tyne Crossing, removing the blocking impact of A19 traffic; An additional left turn approach lane is to be provided on the A1300 John Reid on the north bound approach to the A194 / A1300 John Reid Road roundabout. The existing pedestrian refuge is to be removed and replaced with an uncontrolled crossing; Provision of shared 3.0m cycleway connecting A1300 north of Stirling Avenue to Hadrian Road via A194 Leam Lane with the existing controlled crossing upgraded to a Toucan Crossing Widening the A19 southbound off-slip entry to Lindisfarne roundabout to accommodate large goods vehicles and increase capacity; and, Improve surface water drainage at Lindisfarne roundabout, to reduce the risk of flooding and make the strategic and local road network more resilient and reliable. An outline drawing of the main proposals is included in Section 2.2. 1.4 What the Project will Achieve The proposed scheme will deliver a series of improvements to the local highway network and provide wider economic benefits to the North East economy. These include: Contributing to the facilitation of access to over 100Ha of future employment development land, including the International Advanced Manufacturing Park (IAMP) on land that spans the Sunderland and South Tyneside districts, located to the north of the Nissan automobile manufacturing plant. This is forecast to generate over 5000 jobs by 2024; Opening up residential development land, allowing the construction of up to 5000 dwellings; Reducing congestion on the local and strategic highway networks; Decreasing average journey times and improving journey time reliability for trips through the corridor; Providing more efficient access between South Tyneside and the strategic highway network - the A19 and A1(M) via the A194(M), as well as the surrounding
