The A381, just outside of Totnes, will be closed during the week commencing 3/6/2020 (NB: start date put back from 1/6/20 on 29/5/20). This is to carry out remedial work to the landslip that occurred earlier this year where the traffic lights have been put. The work is expected to finish on Friday 5/6/2020.
The work will safeguard that section of carriageway from further potential landslip debris/falls.
The official diversion route using roads of equivalent category is to take the A385 to Paignton, A380 to Newton Abbot, and rejoin the A381 out of Newton Abbot and vice-versa.
Here’s a link to the Formal Notice of Closure.
