  1. In this list there could also be two highway tunnels in The Netherlands, the Gaasperdammertunnel €5 billion ($5.5 billion), a 3km 5 tube tunnel with 11 lanes on the A9 highway and the Middendelflandtunnel €2 billion ($2.2 billion), a 7km 2 tube tunnel with 8 lanes on the A4 highway and the 12 lane wide aquaduct of highway A1 €6.3 billion ($7 billion). Just outside the list would be both A2 tunnels, a double deck 4 tube 8 lane tunnel of 2.5km and the 5 tube 12 lane tunnel of 1.75km, both just under €1 billion. So the list isn’t complete and isn’t correct.

  2. Wrong & biased & incomplete information. Please do proper & thorough research before posting such videos. Delhi-Mumbai expressway clearly should be there in top 3 but isn't even there in your list

  3. There are several projects you missed. Even one in my city which if it weren’t for others missed shouldn’t make the list. The Calgary ring road is 101 KM long and cost about $3 Billion US to build. It includes 48 interchanges and 197 bridges. It is also Canada’s longest ring road.

  4. $1.3 billion for a highway through porous volcanic rock mountains on a remote island in the middle of the Pacific? That's nothin. Kamala Harris spent $1.3 billion in 100 days running for president and still owes contractors some $20 million… AND she lost the race.

  5. Using the total cost is one way to rank roads I guess, but al it does is favor longer roads over shorter ones.
    Cost per mile or kilometer is a more logical approach to rank these roads.

    If you build a bicycle path long enough it will eventually cost more that any road on this list, but the cost per mile would be several times less than some of these highways.

  6. WestConnex Sydney Australia is not on your list. Costing approximately $US28 billion it connects Sydney’s South West and Western Freeways with an additional 33km of roadway of which 22km are tunnels. Really not sure why you missed this infrastructure behemoth.

  7. Sydney's WestConnex is not in this list. It is the world's largest underground motorway network with mainline tunnels being 22km long and 5 lanes each way at the widest point. The network also features the world's largest underground three-level interchange, known as the Rozelle Interchange. WestConnex was completed a year ago, though two separate tunnel projects will connect to WestConnex in the years to come, relieving traffic congestion on nearby bridges and viaducts.

    Cost: $17bn – $40bn, depending on who you ask.

  8. the Stockholm Bypass would have fit in on this list I think if you go by the price tag, last I heard it's cost/budget was at 3.6billion dollars and it's a underground road/tunnel that is suppose to help eliviate the traffic through Stockholm. if I remember correct it's between 21km and 35km (I remember seeing 2 distances but I don't know if it's 21 total or 21+14km)

  9. I believe the Katy Freeway reconstruction in Houston just misses this list at $1 billion even. One stretch of it is 26 lanes wide, the world's widest. It is part of the Houston Energy Corridor, home to the world's largest Energy companies. It connects downtown Houston with the Greater Katy region, an urban center It it's own right.
