Inadequate notification of road closure

The Southbound A62 at the location on the map is closed with a long diversion in place. From the M62 Westbound there is no notification of this, the dotmatrix signs are showing the times and distances to the next couple of junctions which isn't helpful. The signage should be showing information that the A62 Southbound is closed at Junction 27. The current diversion is to leave the M62 at jnc 27 then divert around a roundabout or two on the A62 and then back onto the motorway at jnc 27 westbound. Down to junc 26 and then back again eastbound to 27 and access the A62.
