Inspection for 'unsafe' Royal Wootton Bassett relief road
A safety check will be carried out on a temporary relief road in Wiltshire which nearby residents say is "poorly-constructed, unlit and unmarked".
The £3m route in Royal Wootton Bassett, which is not yet in use, has been built to save a 24-mile detour while work is carried out on three railway bridges.
But some residents fear the height of the road, just metres from their back gardens, is cause for serious concern.
Network Rail said the audit will advise what measures may be required.
The firm has developed the road to keep traffic flowing while it carries out rail electrification upgrades in the area from next month until 2017.
Keith Talbot of Dunnington Road has described it as a "relatively narrow, poorly-constructed, unlit, unmarked road, raised quite high in the air above the levels of the back gardens of the houses adjacent to it".
He said it needed making safe with crash barriers and markings.
Another Dunnington Road resident, Caroline Redmond, said "clarity" was needed on the "many issues" they have raised with Network Rail.
Network Rail said depending on the audit findings, road markings and barriers could be introduced, and that the majority of concerns raised by residents were "already in hand".
It added that there are no plans to make the road permanent.
