The Seven Arches Bridge is a historic bridge in Newport, County Mayo, Ireland. Built around 1892, the bridge is a seven span squared red sandstone structure with limestone detailing over the Black Oak River/Newport River. It carried the Achill branch of the Midland Great Western Railway line,[1] with the last train running on this line in the autumn of 1937.[2] It was recently restored as part of the Great Western Greenway, the longest off-road cycling & walking route in Ireland.[3] The bridge is listed as a Protected Structure for County Mayo, number 112.[1] Technical DetailsThe single track viaduct has an overall length of {{convert|305|ft|m}} and width {{cvt|18|ft|6|in|m}}.[4] The seven segmental arches have a {{convert|37|ft |adj=on}} span, with a rise of {{cvt|12|ft|6|in}}.
