I thought it was a rather large engineering undertaking for Pakistan so I just searched for "new bridges in Pakistan" (not in quotes for the search) looking for images - I think the 5th or 6th image matched the structures in your picture and similarly in "short videos" I found a few from that project. It's quite impressive and much better than any of the mountain passes I've travelled in Romania.
Just to add few words here... It's a "Fort Munro Steel Bridge". It is the 2nd largest steel bridge in Asia. Actually it's eight steel bridges that are inter-connected with each other to make a single bridge that spreads over 1.5 kilometers. It was engineered in collaboration with Japan.
No street view but this is best you can get a view from the top of the bridge

These trucks reflects the "Pakistan Truck Art". These are two Hino Trucks that are decorated in traditional Pakistani Style. It roughly costs around 1 Million Pak rupee (3500$) to decorate a single truck like that.
