I removed the extra (double walkway), removed the detail from the individual node. it was pretty good, keep in mind that as it is now it pretty much has the bare details which is all that really required. and also it is tagged as a walkway meaning that no bikes would be routed through this alley, if bike are allow it should be changed to "path" which means anything can use it except for motor vehicles. I added a turning circle node based on the imagery and tidied up some surrounding roads.
