| Abstract: |
Meir Tunnel, 284 metres long between portals, forms part ofthe upgrading ofthe A50, through a heavily trafficked urban area of Stoke-on-Trent in England, to dual carriageway. Construction was preceded by the diversion of a large number of utilities, followed by temporary traffic diversions. The walls ofthe twin cell were formed by contiguous bored piles; ground was then excavated to a depth of 2 metres to enable the roof slab to be constructed. Excavation was then carried out beneath the roof, the base was cast, carriageway laid, linings, lighting and controls installed. The tunnel is self-ventilating. Varying levels of lighting are provided; radio rebroadcast facility is provided for emergency services; three crossover openings are provided in the central wall. |
