As part of the overall Quays development, the Council is seeking to deliver a new pedestrian and cycle footbridge between the north and south banks of the River Avon spanning the quays. The Bath city Riverside Enterprise Area was awarded status in 2013, and in April 2016 will receive full Enterprise Zone status (from hereafter referred to as the Enterprise Zone). The Quays Bridge will deliver a vital piece of independent highway infrastructure creating a much needed additional river crossing for this area of the city, as well as providing a safer, vehicle-free pedestrian and cycle route from the south directly to the city centre. The new bridge will land within a significant new area of public realm (Bath Waterside) which also delivers significant new infrastructure improvements along the northern bank of the river Avon, delivering enhanced opportunities for cycling and recreation. Both the north and south landing points will tie into the existing urban and riparian landscape, as well as key strategic routes and ongoing regeneration projects. The Quays are centrally located within the Bath Riverside Enterprise Zone and are key sites for delivering economic growth in key sectors, in line with wider WoE aspirations. B&NES has high aspirations for the site and is keen to deliver the transformational redevelopment of quays into a new mixed-use central business district targeting WoE growth sectors – high- tech, creative & digital and professional business services. The Quays will provide much needed modern office accommodation to support Bath’s flourishing high-value business sectors, and will be the keystone in realising the delivery of the Riverside EZ. Crucially the bridge will enable pedestrian and cycle flow between residential areas to the south of the river and key employment sites in support of this economic growth. Collectively the Quays represent the largest development opportunity within the city since the Southgate shopping centre and the largest office scheme ever within Bath. The Bath Quays North and South projects and will support those projects in delivering a new central business district for the city which will deliver circa 2,800 jobs (gross) on site and deliver direct GVA uplift approaching £160m. The wider strategic objectives are based upon the need to support job growth whilst unlocking capacity on the highway and public transport networks by encouraging more sustainable commuting in order to enable this growth; as well as improving citizen health and wellbeing. A planning application for the bridge has been submitted and was validated on 07/11/2016. The scheme is estimated to cost £4.1 Million, of which the Council are applying for £425,000 of LGF funding to aid delivery. Project construction is forecast to support 27 construction 2 Doc v.1 Last updated May2016 Submission date:30/11/16 Submitted by: B&NES Approved: jobs. The proposal will help to deliver the aims established in the WoE 2030 vision and the Council’s Core strategy aims.

B&NES submitted a planning application relating to the bridge, which was validated on 07/11/2016. The bridge shall become a Highways asset and be vested in the name of the Highways Authority, who shall oversee the maintenance and operation of the bridge. Procurement of all contractors needed for delivery (design, construction and associated works) of the bridge will be overseen by B&NES and will comply with necessary legislation and guidance. B&NES has a dedicated Project Manager function to ensure the delivery of Quays Bridge. The project manager will co-ordinate all works and programme. 2.0 Project Description The project will deliver substantial connectivity improvements to this part of the city, providing an additional non-vehicular crossing point between Midland and Churchill Bridge. It will form a vital piece of highways infrastructure and strategic route directly linking the large residential areas to the south of the river, including Oldfield Park and Bear Flat to key employment sites in the north. Delivery will realise two important components of the Council’s long-term Core Strategy - opening up the heart of the city via a safer and more sustainable route for Bath residents. Moving forward, the bridge will also serve an important function in forming an intrinsic physical linkage between the two prime regeneration sites of Quays North and South, and facilitating access and movement to these new key employment sites. Synergy will also exist with the Bath Riverside Project by further enhancing the connectivity of Bath to its river through the Quays Waterside project – a remodelling of the north bank as part of flood mitigation measures into a terraced riverside public park (RIF funded under separate business case). The unique and stylish bridge will be a focal point for the Quays development as well as in redefining this area as a central business location within the Riverside EZ. 3 Doc v.1 Last updated May2016 Submission date:30/11/16 Submitted by: B&NES Approved: Crucially the Quays will deliver a critical mass of new Grade A office accommodation, injecting much needed office stock to the city. Collectively, the Quays projects will deliver circa 2,800 jobs (gross) on site and deliver direct GVA uplift approaching £160m. The Quays Bridge will therefore become a key piece of public infrastructure which will assist in in delivering the creation of Bath’s new business district and in securing long-term economic growth to the benefit of Bath and the wider West of England. The Site of the proposed bridge consists of three principle land elements: • the River Avon; • the north bank of the river; including part of the newly landscaped riverbank and the Bath Quays North site, and; • the south river bank; including the existing arches (BMT land); the existing river wall (including the jetty) and Buildings 7 & 8 (Bath Quays South site). Hereafter they will be referred to as: the north bank, the south bank and the river or river corridor. The design team (Marc Mimram/Webb Yates Engineers) and their concept design for the bridge were selected via an international design competition, commissioned by B&NES in 2015. The team are appointed under an NEC3 Professional Services Contract to deliver a fully-detailed design of the bridge, thereby securing planning consent for the proposals and technical approval from the Highway Authority. CH2M Hill has been appointed by the Council as design checker. Bridge project comprises of four key elements: • demolition of existing buildings and structures; • provision of new bridge crossing of the river Avon for pedestrian and cycle use; • new public realm on the North and South river banks, and links to the existing highway network, and; • provision of a new river wall to both support the south end of the bridge and act as a flood defence. The bridge takes the form of a dual-span steel superstructure supported by a combination of piled reinforced concrete, and sheetpiled substructures. The deck comprises a shared pedestrian and cycle surface, with no segregation between users, to be in keeping with the general design approach of cycle paths on either side and generally within Bath. The proposed bridge will have a deck length of 60m with a usable width between handrails of 4.3m, which exceeds the preferred minimum set by Sustrans. The deck will be surfaced in natural stone and ambient lighting incorporated in the handrails. At the time of writing the design has been taken to RIBA Stage 3 and submitted for planning consent. Technical approval of the design proposals by the highway Authority is ongoing. 4 Doc v.1 Last updated May2016 Submission date:30/11/16 Submitted by: B&NES Approved: Please refer to the Planning Application reference on B&NES planning portal for more detail of the proposals: (16/05349/REG13). Specifically, it is envisaged funding for the 16/17 financial year will be used to enable pre- delivery preparatory works and surveying for bridge design. The bridge completion and associated public realm works on the south landing will be phased to coincide with delivery of the office developments in 2018. Various studies have been undertaken to support the planning application for the bridge. These include Heritage, archaeological, ecological and transport assessments, all of which can be viewed on the B&NES planning portal. The Transport Assessment confirms the bridge will have the capacity to carry between around 330-690 pedestrians per hour and between 100-310 cyclists per hour, or between 640-790 pedestrians and cycle combined depending on the proportion of the two user groups. This is viewed to be sufficient capacity considering envisaged future use of the bridge.
