8.1.1 Context Although this is a conservation strategy for the canal, it is recognised that the major engineering sites will have a major impact on landscape, disturb the community while in progress, and affect some households in the long term. It is therefore appropriate to briefly outline some of the potential solutions here. It must be emphasised that some of these plans are at an early stage in thinking, and local consultation will follow when more detailed plans are prepared. Some plans from the 1987 Parliamentary Act no longer meet current standards, due to increased traffic on the A483 and improved safety requirements. 8.1.2 Phase 1 Works (Gronwen to Arddleen) • Bridge 86 School House Lane, near Pant. A small brick or brick faced bridge to the south of the current crossing, as in 1987 plans, remains the preferred solution. • Bridge 93 Walls Bridge, Carreghofa. A possible detour, as shown in Figure 8.2, seems likely. This takes the junction further away from the local primary school, and also the bridge from the road junction. Earlier plans also diverted the canal to take the bridge further away from the junction, but this may not be necessary. • Bridge 96 Williams Bridge. A new structure over the canal at this point, with current visibility and safety requirements, would be extremely expensive and dominate the immediate area. The preferred options under consideration is an electrically operated lift bridge with traffic lights. • Bridge 102 Maerdy Crossing and 103 Arddleen. Plans for these two crossings are complex and need to be considered together. A detailed study looked at seven different options, and was stimulated by plans for a new road junction between the A483 and B4393. Option 4A, shown in Figure 8.3 is perhaps the most likely option. It has a low landscape impact, and will have relatively low disruption during construction. The diversion enables the canal to cross under the A483 at a slightly higher point, with a very tiny raising of the final carriageway. Under this scheme, two options remain at Arddleen: 1. The canal can be lowered for a short length, and operated by a modern drop lock and pumping system. 2. The carriageway can be raised over a long incline, with a new and higher bridge installed, similar to the work at Whitehouse Bridge, Welshpool. The first option is currently considered the more likely solution. Phase 2 (Refail Bridge to Freestone) • Refail Bridge, the current southerly limit of navigation, needs further study. It is very near the A483 for either a humpbacked bridge or a lift bridge. Plans to divert the canal through a tunnel to the west of the current route exist, but have many problems. Garthmyl is the historic terminus of the East <strong>Montgomery</strong>shire <strong>Canal</strong>, so a viable resolution of this crossing is very desirable. • Bridges 131 and 132 Nag’s Head, Garthmyl. Plans for this crossing may need major revision from those agreed in the 1986 Parliamentary Act. In order to make full use of the feasibility study for work into Newtown, the engineering and costings of this crossing need to be revised. • Bridge 136, Fron, Garthmyl. The route remains essentially the same, as in 1986 plans, to divert the canal slightly north. • Bridge 141, Red House. 1986 plans to divert the road over the canal, slightly to the south of the current alignment remain. Phase 3 The land is not in British Waterways ownership, and there are many obstacles in the way, including minor road crossings, Newtown’s main sewer, River Severn flood defences, and development within Newtown. These issues were addressed in a recent study commissioned by Powys County Council, which concluded that the preferred route should include an aqueduct over the River Severn and a terminus to the east of the river. 145
