同学你好~
高速公路在美国，一般表达为：freeway / highway / expressway
freeway的英文示意：(in the US) a wide road, where traffic can travel fast for long distances. You can only enter and leave freeways at special ramps .也就是（美国）高速公路哦~
motorway一般是用于英国，英文释义：
(in Britain) a wide road, with at least two lanes in each direction, where traffic can travel fast for long distances between large towns. You can only enter and leave motorways at special junctions .也就是（英国）高速公路
tolled表示收费，一般高速公路用highway即可，不需要加tolled强调收费哦~
希望对同学有帮助~
