A bomb squad was sent out to retrieve a grenade lying near the side of the A483 .
An Army team was dispatched to the dual carriageway between Chester and Wrexham on Monday (March 27).
The explosive was found between the Posthouse Roundabout and junction 7 for Rossett.
A police car and Explosive Ordnance Disposal vehicle were parked up in a lay-by. The scene has now been made safe.
Fortunately there were also no delays for drivers.
A witness said: “I was driving on the A483 to go to work and saw a police car parked up in a layby just after Rossett and then I saw the Bomb Disposal van.
"It was quite a surprise and everyone was slowing down to have a look as you don’t often see that sort of thing on the side of the A483."
The Ministry of Defence has been contacted for comment.
