Highway construction (cost)

i really want to know, how much it would cost to build a certain length of road. just give me your estimation of how much it would cost to build.

That depends heavily on terrain. Tunnels and viaducts are expensive. But also, in flat terrain there can be huge differences.

Like in Poland, they construct a motorway for 2 - 4 million euro's per kilometer, but in the Netherlands, our A4 is likely to cost 100 million per kilometer. I am wondering if they make gold "shiny" crash barriers for that ridiculous amount of money.

so on average are roads expansive? like let's say i was to build roads in a grid, with pipelines, sewers, telephone lines, internet lines, etc; with a 1km X 1km grid how much would that cost.

Your question doesn't really have a particular answer, because as was already mentioned, there are tonnes of factors involved.

I think in addition to what other forumers have mentioned, the type of road is also important. Judging from your last post, it seems that you are referring to a regular street as opposed to a motorway. And even here, there are variations. A 1km worth of a small residential street will not cost nearly as much as a 7-lane avenue (like most main streets here in Toronto).

Another factor to consider (which is related to location) is whether you are building the road in the middle of nowhere (for example, in a completely new neighbourhood that is yet to be built), or amidst pre-existing development. The latter would be much more expensive.

But to answer your last question - yes, building roads is definitely not cheap. In the developed world it would probably be much more expensive, but on the other hand the developed world can afford to spend more money. If building roads would have been very cheap and simple, most places in the world would probably have excellent road infrastructures, but this is far from being true (unfortunately).

Oh yeah, and you mentioned many other utilities in addition to roads (pipelines, communication lines, etc.). If that is included in the price, then that changes the question dramatically. Here you definitely do not have a definitive answer, but rest assured it would cost a lot of money.

Most expensive motorways/highways in your country

Wondering, how expensive are some motorway/highway projects in your country? Per km or total, doesn't matter, just give some most obvious extremes.

I think the A4-Midden Delfland (motorway from Delft to Rotterdam, 7 kilometers), is about the most expensive, estimated at 700 million euro's for 7 kilometer of roadway. That is 100 million per kilometer.

There are several reasons for this high costs.

The A4 would run through a nature-sensitive area in the Randstad, the last larger green space between Rotterdam and The Hague, spanning 3700 meters between the suburbs Delft and Schiedam.

So, in order to build this motorway which was planned and partially constructed during the 1960's, many obstacles have to be taken. In the 60's, they build a dike where the A4 should have run on, because of the bogs, a motorway at grade would slowly sank away in the ground. Several other motorways in the Netherlands have been constructed this way, most significant the A12 from Utrecht to Gouda.

Since a motorway above grade would be unthinkable these days, a motorway below grade or even cut&covered needs to be constructed. But how do you construct a motorway in an area it would slowly sink into?

Space is not really an issue, since there has been a 120 meter wide zone left open for this motorway within Schiedam. Interchange Kethelplein and Exit Delft-Zuid are fully prepared for this construction. Some parties want this A4 to be covered through Schiedam, adding to the expense.

The cheapest way would be to construct this 2x3 motorway at the current dike at a fraction of the costs of the proposed plans, however is highly unfeasible. Most people which are proponents of the construction are so tired of this 45-year debate, they say it has to be constructed at any cost, as fast as possible. The adjacent A13 and Interchange Kleinpolderplein cannot take anymore traffic while massive housing projects have been started in the entire area since the 1980's, generating even more traffic.

Croatia - they say that it was A2's last section Krapina - Macelj. it costed about 15 million €/km. little bit more expensive is upgrading Rijeka's bypass (A7). now it is 2 way road with multilevel intersections and is being upgraded into 2+2. so those 2 new tracks cost about 9 million €/km.

In Slovenia, there is currently newly opened section Šentvid-Koseze on A2 (or closed-depends on quantity of falling material from tunnel ceiling), which costed total 240 mil. € for 4,5 km (55 mil. € per km), with 130 mil. € and 1,5 km long tunnel (about 100 mil. € per km), pretty large interchange and other things. It is still not finished, connection inside tunnel is still being built and will cost additional 15-25 mil €.

Longer and a bit older section over Trojane hills (4 tunnels, 13 viaducts, 16 km) costed about 450 mil. € (about 30 mil. € per km).

In Morocco the most expensive section in service is the A4 on the southern shore of the strait of Gibraltar. The 54 km section cost 74 million dirhams (€6,5m) per kilometer to construct due to the very mountainous terrain. That's almost twice the cost of the second most expensive section. But in an international context I guess it's quite cheap.



For Sweden, the most expensive piece of motorway is the Södra Länken tunnel system. The system, excluding connecting tunnels, is 6 kms and cost 7 billion SEK (€750m). Then again, the connecting tunnels are 11 kms which brings the total to 17 kms. A very controversial road before it was built, but now it has reached it's maximum capacity only four years after being opened.

In Slovakia the most expansive U/C section of motorway is D1 Sverepec - Vrtižer which costs about EUR 300 million for 9,5 km long motorway (more than EUR 31 million per km).

But this one is quite cheap in comparison with other planned sections. E.g. 8.1 km long section D1 Višňové - Dubná Skala should cost more than EUR 663 million (almost EUR 82 million per km). Little bit cheaper should be 13.5 km long D1 Turany - Hubová for almost EUR 680 million (EUR 49.5 million per km).

If we are talking about national roads, than there is no competition for planned section of I/59 Slovenská Ľupča - Korytnica. This about 15 km long section should cost from EUR 644 million to EUR 1.161 billion what is from EUR 43 million to EUR 77 million per km.

1 kilometer of 2x2 tunnels in Puerto Rico's freeway #53,cost is over $300 million(dollars).

Why was this project cancelled in an almost ready state?

Was the A13 built to be a replacement of the missing part of A4?
How could it be built when the A4 couldn't? (it's also an above grade motorway)

And what about the A4 south of Rotterdam?
It seems to me the A29 will be part of it. (at least the Klaaswaal - Dinteloord)

First of all, the A13 was present during the construction of the A4, but there are two metropolitan area's of both around 1 million connected only by the A13, and also very few other local roads. This continues to this day.

The construction of the A4 was halted in the 1960's, and a vote in the cabinet followed, which was rejected because one politician thought he voted for the A4, which was in reality a rejection of the A4. Kinda stupid that this mistake still has it's impact to this day.

The A4 south of Rotterdam is also a long-term plan, with no sight of a speedy construction, except of the A4 around Steenbergen, which will soon be under construction, which has, in my opinion unnecessary high costs because locals wanted the A4 to run west of Steenbergen, which requires an aqueduct, and has a longer routing. However, proposing an eastern route will only slow the project down even more, so they're set with the western route.

In France, the A45 will be 1.6 billion Euros for 40km. It will twin the A47.
11 viaducts, 8 tunnels (some over 1400m long), and a high environmental quality are responsible for this fairly high price.

what's the problem with the eastern route?
and what kind of "aqueduct"?
