Type 2 Dual Carriageway: the cost per km

Tech3

I have seen various action groups against new roads quoting figures from the sky for future schemes. On the N21 Action group website there are quoting a motorway build cost which is incorrect as the N21 Adare-Abbeyfeale scheme is getting done as a 2+2.

So what is the cost of a 2+2 per km over a motorway, WS2 and S2?

Motorway is on average €10 million per km.

Well the Dromod-Rooskey stretch of 2+2 cost €84.5 million, going by the NRA site it has 7.6km of Type2 Dual carriageway + couple km's of ancillary roads etc.

Of course construction start in 2006 so no doubt they paid through the nose on the CPO's. I found an article from 2004 which puts the proposed total costs of it as a 2+1 at €53million. That estimated cost was at start of CPO process and before they redesigned it as 2+2.

Did Gort Crusheen not come in at €90m for constructing 22km of motorway + some local road bits and pieces ex land acquisition and the consultants. The total project cost was claimed to be around €200m.

The cross section and land take is lower on 2+2, furthermore the costs of land acquisition and contracts ( both) have fallen since Gort-Crusheen which land was acquired at the peak and contracted out shortly after the peak.

I would estimate that 2+2 would come in at €5m-€6m a km right now unless they hit a complicated Annaholty type scenario or a long land bridge.

Also note that no future schemes are proposed in areas with expensive land....bar the Galway City Bypass perhaps and a few bits near Cork City.

Thinking about it just about all the 2+2 is in rural areas with low land cost - except possibly for some ends near Limerick and Waterford on the N24 if that gets built. The other stuff near cities (N28, Galway, CNRR, M20 etc) will be HQDC or motorway.

Surely you'ld want to separate the construction cost from the land costs?

and then compare avg land take per km vs full blown motorway

That is fairly simple. A fruity value nowadays given where 2+2 construction is actually proposed would be €15k a Hectare ( 10,000 sq metres)

The land take for a 2+2 would be 40m, again being generous. that is 400,000 sq m per km or 40 hectares @ 15k a hectare. €600k.

Even adding one country bungalow per km @ €200k and the cost of land is still only €800k per km.

no its not!!

a km is 1000m
a strip wide of 40m, 1000m long = 40,000 sq m

so only 4 hectares need to be acquired per km of 2+2
so @€;15k per hectare land cost, only €60k per km of 2+2.
