A303 dual carriageway and Stonehenge tunnel plans

A major road which stretches from Hampshire to Devon will be made into a dual carriageway, with a tunnel taking traffic past Stonehenge, the government has revealed.

Sections of the A303 are renowned as being highly congested, especially during the summer months.

The plans are part of a £15bn road-building package which was announced earlier.
