You have three routes after leaving motorway
1. Gojra >jhang >shorkot>kabirwala>multan
2. Gojra >toba tek singh>shorkot >kabirwala>multan
3. Gojra>Toba tek singh>rajana>kamalia> chichawatni>khanewal>multan
Route 1 is driveable but comparatively longer. On Route 2, being the shortest, road condition is pretty much rough. Route 3 is shorter than route 1 and the road is fine atm.
Avoid fog timings due to lack of lane markers and road signs and the roads are two way till you reach N5. Drive in night if you can to avoid the traffic here.
P.s: all the roads are two way after leaving motorway till you reach N5.
Hope this helps.
