Great Dorset Steam Fair plans road network
A permanent road network is to be built on the site of the Great Dorset Steam Fair following disruption of the event caused by bad weather.
Tractors were brought in to help move exhibits during 2014's show when the ground cut up badly after heavy rain.
More than 3 miles (5km) of new roads and changes to the layout of car parks are planned before this year's show at Tarrant Hinton in September.
Organisers said the move would "greatly improve access times".
The event, in its 46th year, regularly attracts up to 200,000 visitors to fields near Blandford but the wet ground last year meant displays had to be cancelled as steam locomotives and other vehicles were unable to move around the site.
Organisers said the decision to build a permanent internal road network on the 600-acre site followed lengthy meetings with the emergency services and local authorities.
Under a new layout, exhibitors and public campers will gain access to the site via different access points.
It is hoped the new roads would be built, subject to planning approval, in time for 2015's show.
