The final stage of the building project for Cornwall's new A30 dual carriageway around Truro is taking place. It has already been delayed by three months, builders say the new section should now be open from the early summer. Along the road is eight miles of new Cornish hedging - but building that hasn't gone smoothly. Martha Dixon went along to meet the specialists building the Cornish structures with techniques that date back 3,000 years.
