A.Many an accident has taken place on this route.
B. Today again, driving enthusiasts wait with bated breath for the Rohtang La to open to take a jaunt to Leh.
C. And yet the beauty of the place and the thrill of adventure beckon many a tourist every year.
D. The landscape remains as beguiling and awe-inspiring as ever.
E. Even 10 years ago, this epic Himalayan journey was a risky endeavor.

Reading through the sentences, we see that B-D forms a pair as B talks about the journey from Rohtang La to Leh, and D tells the reason why that is the case, because of the beauty of the place. 
E then starts to explain why this is a topic of discussion, because of the journey being risky, to which A provides context, noting that it is still risky. And finally, C serves as a conclusion to the two points, stating that the adventure, although dangerous, has attracted many tourists every year.
