A3 in both directions closed stationary traffic, long delays due to emergency repairs at Hindhead Tunnel.
The tunnel closed just after 17:30 due to a systems failure. A specialised engineer is required and is travelling from Derby, so the tunnel is expected to be closed until at least midnight.
Diversion - Northbound traffic is advised to follow the solid diamond symbol led diversion following the A325 n/b and A31 e/b to rejoin the A3 near Guildford.
Diversion - Southbound to follow the solid triangle which is the reverse route.
