This road is referred to as Khayaban-e-Jinnah not "main boulevard".
All the way from Defence Chok to Wateen Chok via Ghazi, Masjid and Lalik Jan choks its called this.
Hence,
LAHORE | Khayaban-e-Jinnah (Defence) Signal Free Corridor | 5 KM | APP
Plus I think small local projects like this should be moved to the respective city forums. It's not a major project like the ring road or the new ravi bridge etc. Just an opinion.
Also every road in Lahore has been wrongly named on Google Maps...for example Gulberg Boulevard (again wrongly labeled main boulevard) extends from Fawara Chok to Y Chok via Kalma chok. On google maps someone actually calls it "main blvd gulberg" from fawara to kalma chok and then "main blvd garden town" from kalma chok to y chowk. Like wtf...why make things so complex? There's a road in Johar Town on google maps actually labelled "NFC main boulevard"?

these are not official names...these are names people posted during mapmaker days...and nobody has bothered to correct it.
BTW how many of you know the official name of Canal Bank Road?
