The trail shown on this map is true to survey.
In several places along the open sections (shown in blue) the present trail leaves the survey and follows side roads or tracks to bypass bridges that may be decked and railed in the future.
Therefore, if you need a gpx file for an open section, download it from the individual maps.
Tapping this icon on the map will show a link to the map for that section.
Links to the individual maps are also available in the location boxes on the side/below of the map.
Great to hear this rail trail is progressing
