Work to stabilise a road tunnel in Dorset where two people were killed in a landslip should include a memorial, a councillor has said.
Rosemary Snell and Michael Rolfe, from Somerset, died when their car was buried at Beaminster Tunnel in July.
A design for a concrete hood over the tunnel entrance is the favourite of five solutions put forward and would take six months to complete.
Dorset County Council engineers have dug 25 metres (82ft) into the hill to establish the structural stability of the tunnel.
Councillor Rebecca Knox, who has called for the “quickest and safest” option to be chosen, said that as the tunnel already features a memorial to a worker who died during its construction it would be right to commemorate Mrs Snell and Mr Rolfe.
Mrs Knox also said that traders in the town had complained that the closed road was affecting trade.
The bodies of Ms Snell, 67, and Mr Rolfe, 72, were found nine days after they went missing from their homes in Somerset on July 7.
