between Echo and Dwinell is layout of paths correct? Cyclable? Surface? Width?

Is it Street Car Trail or Streetcar Trail? Is this an official local trail?

Sand Lake Trail cycle route relation extents should be surveyed

this line looks like it used to be a abandoned railroad but it's really not visible on the ground

Cycle route goes NW, NE, and SE from here. Evidence are three bike route signs. Extent and name (if any) of route(s) is unknown. Requres survey and/or study of city/county records.

this path does not intersect the road. Instead it goes to the E and ends at Cleveland St

Based on observation there is a 3m wide multi use trail on the N side of 181st Ave from here to west. Regrettably there is no curbcut of at the E end of it. The new section joins the section near Nixon St
