Another bad day of travel

Another sad day of traveling to office (Y). As depicted in the diagram, Route A is our normal route to office. Today we hit a traffic jam at point X at around 9:15 a.m. Smart that we are, we decided to take the alternate Route B to office. As we neared route B, we realized that Route B is closed for repairs and that is the reason for Route A getting clogged badly. So our bold bus driver decided to go for Route C. Apart from him no one else knew that route C existed before today. Halfway into Route C, he realized that the bus is too big for the narrow dirt road and decided to turn back. So we were at the start of route C (point Z) at 10:10 a.m. deciding which route to take. Sadly the road from point Z to point X was also badly jammed by this time.
At this point my patience gave up and I decided to hitch a ride. Luckily I got a biker who took me through route C to my office. I have tried my best to show the dangerous and curvaceous route C as it is. Finally at 10:30, we won the war and reached office after crossing a series of streams, potholes and the road (so called). Thanks to the daring biker!!
Its 11:10 now and my bus is still not here. The green question mark is probably where it must be.

The bus finally arrived at 11:35 a.m. As per one of my friends who was in it, the driver tried out another imaginary route D, which did not exist, before coming back to route A.
