The spur that continues straight at 1,265 m el. and then goes north in the direction of Klesilkwa Mountain (right after the creek crossing, where branch 2300 turns south) is drivable to the very end. A 4WD vehicle with high clearance should be able to make it to the creek crossing at 1,255 m el. A 4x4 will take you across the creek and further to the end of the road at 1,420 m el.
