Detail

The high loads grid collection of advisory routes for extremely high loads in Scotland can be found on the Transport Scotland website.

Use the ‘High and heavy load grid map’ as a guide to locate routes in a required area. Descrip­tions of these routes are available in the ‘Heavy load grid routes’ and ‘High load grid routes’ documents. Each document con­tains a list of routes with capac­i­ties and full descrip­tions of each route.

The Heavy Load Grids are defined by a set of cat­e­gories A+ to F which relate to a set of vehi­cles on 12 and 14 axle trail­ers. Full descrip­tions of these vehi­cles are avail­able from the ‘Heavy load vehicle classification specifications’ document.

High load routes allow loads with a height of either 18′ or 20′ and the heavy load route cat­e­gories start at loads of 223.52T on 12 axles or 259.08T on 14 axles.

If you have a suggestion for a new route, or a change to a route, to be considered for the high and heavy loads grid please con­tact Highways England’s abnor­mal loads team. Newly sug­gested routes will need to be equal to or greater than the specifications of the existing routes. The sug­ges­tions must also be to or from loca­tions with a criti­cal need to move loads of this nature or be on reg­u­larly used routes.
