We rode along H02 /Prithvi Hwy(H04) - out of Kathmandu to Pokhara - yesterday, Thursday-5th.
[Actually, we're in Bandipur right now, therefore still some 75 km until we get to Pokhara.]
We encountered two major hold-ups along the way. The first was caused by an articulated truck that went over into the ditch and shed its load. This was on the twisty mountain section going out (west) from the KTM valley.
The second accident, about an hour or so further on .. was bad. Fatal, in fact. Makeshift stone barriers either side of the incident halting traffic in both directions. Police, Army in control of the scene, which, seeing we were foreigh travellers, waved us to drive-on through. We could clearly see that a motorcycle was involved. A smashed-up bike with two lifeless men lying alongside with their faces covered. No-one attending to them, so they were obviously both killed. Not nice.
We saw at least three other vehicles abandoned in the ditch in addition to the above along the way.
: mostly the road is in reasonably good condition and shouldn't be a problem, but the mountain downward twisties west out of KTM appears to be in a state of constant repair/disrepair. Be cautious on that stretch - and watch out for a few more broken sections. Otherwise it's no problem. Indeed, incidents excepted, it's quite an enjoyable ride.
