Object auto rotating?

Everything was going to plan until I got stuck here..

The object keeps auto rotating to the wrong way round when I go to attach it to the spline..?

Any way to reverse this or flip it round?

F9 is used to rotate pieces - however, that particular piece you are trying to align is very fussy. What you must do is rotate is manually a small distance from the road, then extend the road to 'meet' it.
