causeway = a raised road or path, as across low or wet ground.<br/><br/>Does `low' mean here `dry'?<br/><br/>Also, I think <b><i>across </i></b>means <b><i>(A road which is in middle, and its both left and right side are covered by low or wet ground)</i></b><br/><br/>Am I right?<br/><br/>Please help me.
