The +Z Highway digging crew is a group formed around late 2016/early 2017. The group started because of the influence of the trend of completing the major Axis highways, created by the +X highway group in late 2016. Many players set out to complete the highway and began to help gRiNdLoRd, DC91, and BobRock who took out to dig the +Z highway in the summer of 2016. The group has currently reached the border on June 9th, 2017.
