Fresh finds at a buried medieval settlement has prompted a wider search at the site of a long-awaited link road.
Archaeologists uncovered 2,000-year-old Roman remains on land earmarked for the South Devon Link Road.
They came across a large rectangular enclosure in December alongside an 800-year-old medieval building near Kingswerswell.
Now another medieval building has been found at Edginswell Lane, with pottery dating back to the 13th century.
Simon Hughes of Bradninch-based AC archaeology, who is leading the dig on behalf of Devon County Council and Torbay Council, said: "This project has been really exciting and we're hoping that we uncover some high quality archaeological remains."
More than 50kg of pottery has so far been dug up, originating from as far away as southern France and Spain.
The 5.5km dual carriageway, which will provide the long awaited bypass for Kingskerswell, was given full approval by the government in May. Work began in October and is due to be completed by December 2015. Further assessment will now take place along the rest of the planned route to "establish archaeological potential".
It is hoped that more detail will emerge around the medieval building as well as around the Roman settlement site at Aller Cross.
Steve Reed, from Devon County Council's historic environment team, said: "If archaeology is found it will be investigated and recorded prior to the construction of the road itself."
Councillor Stuart Hughes, the authority's cabinet member for highways, said: "One of our key concerns throughout this project is to be environmentally aware and we are keen for the archaeological team to continue with its search.
"We do not anticipate that this will delay the construction process and we are looking forward to displaying the findings later this year."
