I feel like a lot of people are still confused between M3 and M4 and dont know that these are in fact two parallel motorways both of which start from Abdulhakim and connect to the Lahore-Islamabad M2. The M4 passes through shorkot ,toba tek singh, gojra and faisalabad and connect with the m2 at pindi bhattian. The M3 on the other hand goes from abdulhakim, shorkot cantt, rajana, samundri, sharqpur etc and connects with m2 near ravi toll plaza.
