Narrative: ATIS information; wind 080 at 7 altimeter 30.15. [I] was given instruction to turn left from northwest heading to intercept final approach for 17 left. Next [given] change to 17 right; contact tower on 123.75. [I] was cleared to land 17 right. [I] was on short final when the next instruction from tower (Go around right side; aircraft on runway) (Extend up wind). The aircraft on runway began take off as [I] was a beam the threshold on right. As [I] was climbing on right side single engine Cessna gained altitude very quickly and began to drift into [my] flight path. [I] turned right and climbed above pattern altitude to avoid collision with Cessna while trying to keep Cessna in view on left side. The tower restated the (instruction that [I] was to extend up wind) [I] then resumed course 17 at tower's instruction. The Cessna could not see the [my aircraft] on the right and above the wing. [I] was then instructed by the tower to turn right for downwind 17 right get back down to pattern altitude 6800 feet and get back on the east traffic pattern restriction. [I] was again given a clearance to land 17 right. Again [I] was on short final when [I] was given instruction to go around right side aircraft on runway extend up wind. [I] was then instructed to turn right for downwind 17 right. Again given clearance to land 17 right. Again on short final [I] could see an aircraft stopped on runway. [I] contacted the tower and asked if this was going to work. [I]was instructed to continue approach for a landing. [I] had already initiated a go around; when the tower gave instruction to go around right side air craft on runway. [I] went around and given instruction right turn for downwind 17 right. [I] was instructed to contact tower on 118.9. [I] was given clearance to land 17 left. [I] landed on 17 left without incident. In my option the operation of dissimilar aircraft in such tight spacing could have been a contributing factor in the near miss. The setting sun may have restricted the view of the tower to the west; not able to see the aircraft on runway to the west. Trying to make a tight turn after side stepping right for a go around doesn't allow enough room for maneuvering. [The highway] converges with the south end of 17 right narrowing that airspace considerably. With a cross wind out of the east the steep bank required to make a right turn; when aircraft are in a climbing turning slow in a steep bank should not be expected to stay east of [the highway].
