This road is a nightmare, it gets better towards SERENJE! The potholes can swallow an entire bike! And no fuel stations, only individual locals selling gasoline in Plastic Cans! Carry your fuel and possibly use the bypass from Tunduma to Kasama and then Connect to SERENJE, it's easier to get to Lusaka that way. From SERENJE to Kapirimposhi the road is good and upto Lusaka the road is good!
