A controversial plan to build a tunnel at Stonehenge should be reconsidered, a Unesco report has recommended.
The report says a short tunnel could damage the World Heritage Site and a bypass above ground or a longer tunnel should not be ruled out.
The findings will be presented to the World Heritage Committee next month.
In January, plans for a 1.8-mile (2.9 km) dual-carriageway tunnel were finalised by Highways England, and a public consultation was launched.
Key points in the draft decision responding to the report, released ahead of the World Heritage Committee meeting, include:
- The 2.9 km tunnel would cause “adverse impact” on the Outstanding Universal Value (OUV) of the site
- The portals at each end of the tunnel would have visual impact, but the extent of new roads within the site is of greater concern
