Richard Jones has been involved in behind-the-scenes work to press for a dual carriageway for the past eight years and is one of the latest to sign the Shropshire Star's Dual It petition.
There have been claims that it would be too expensive to turn the road into a dual carriageway because bridges would have to be rebuilt.
But Mr Jones said: "If the width under the bridges are within a measurement of 19.1 metres, this will allow a small crash barrier to be fixed to the bridge abutments within the one-metre hard strips."
The Shropshire Star needs your help to deliver a petition to dual the A5 north of Shrewsbury to Parliament.
In just two weeks the Star's online and paper petition has already attracted more than 3,300 signatures.
But we need more than 10,000 to ensure that we can take your concerns to the heart of government.
The fears and concerns over the trunk road are plain to see from the comments that those who have already signed it have added to their signature.
Ray Horne wrote: "We have known of the dangers of so called 'three lane roads' for decades. So why is the stretch of road between Nesscliffe and Chirk still allowed to be a potential death trap?"
Ruth Burton said: "I drive in this road to work three days a week and frequently cars overtake multiple cars in dangerous conditions and at dangerous times.
"This is because the road is so wide they think they can make it but so often someone does the same in the opposite direction and is such a near miss – such a high risk road."
