Table A1.2 Links with freight proportions over 20% % National Strategic road network section Freight Rank A30 between A39 and A3058 (AL3088) 28% 175 A30 between A3058 and A3058 (AL1907) 20% 526 6 South West Peninsula route-based strategy evidence report The highest proportions are on the A30 in Cornwall between Highgate Hill and Summercourt Junction and between Launceston and Bodmin.
