Road is excellent but single with very less traffic, just keep an eye on sudden bumps sometimes due to new patch being higher than the older one. We did not feel any issue of security, freely used DSLRs, mobile phones where ever we wanted, took pictures of bazaars & locals. We visited Kot Diji Fort, Old Haveli of Mir of Khairpur and also Mehrano Wildlife Refuge. In fact I have traveled on this route many times before to go to Pacca Chang for buying Qurbani goats. Tea stopovers are there but not as good as on national highway. Our travel time was during day. GPS would come in handy especially at Kumb because if you take wrong turn, you would end up at Ranipur (National highway).
