i have travelled a couple of times btw lhr and khi in recent times...if u are accompanying with another driver....u leave lhr at 4am in the morning....after crossing khanewal...take the multan bypass...(road thru dunia pur)....u will directly reach bhawalpur bypassing multan (will save u 100kms and the road is recently built but single track). if u keep average speed btw 100-120kmph, u can cross sind/punjab border by noon. u can reach sukkur btw 2.00/3.00 pm and on the main road b4 sukkur city, u ll find good restaurants for lunch...thr will be one shell pump on ur right side managed by taj petroleum...thr kastoori kababs are too good along with chicken karahi...
u rest for one 1hr and leave and will reach nawabshah in three hrs i.e. 6.00pm in the evening...it will be complete day light till then (due to day-light saving time adjustment) from nawabshah to khi is exactly 260kms...so max by 9.00 at night u reach at khi....
