Limerick dredging

The Limerick Post has news here.

Value for money

Regular readers will be aware that I think the proposed canal to Clones is a bad investment. I thought it might be useful to look for information about other Irish canal restorations to see what they cost and what the return on investment has been. I understand that there was a study of the Shannon–Erne Waterway, but I can’t find a copy on tinterweb (if anyone has one to lend, please get in touch).

I therefore asked Waterways Ireland about the restoration of the Royal Canal:

I would be grateful if you could tell me the cost of the restoration of the Royal Canal, the annual cost of running it and the revenue it generates.

The reply (for which I am, as always, grateful) said:

Restoration of the Royal Canal commenced in 1987.

€37m Capital Expenditure on the restoration project funded through (1) Operational Programme for Tourism 1994-1999 (2) National Development Programme 2000 – 2007 and (3) National Development Plan 2007-2013.

The Maintenance Cost for 2012 is €2.46m.

The revenue generated by the canal in 2011 is not available.

I didn’t really expect that there would be a meaningful figure for revenue. A full assessment of the benefits would cover far more than the (probably minimal) direct revenue; I think such an assessment should be done, but that’s not what really got my attention.

According to Waterways Ireland, the Main Line of the Royal is 146 km long and has 46 locks and many bridges, some of them newly built as part of the restoration. Harbours have been improved, slipways have been provided and service blocks have been built. And all of this was done for €37 million (I don’t know whether that’s in constant prices and, if so, at which year’s rates: I’ve asked a supplementary question).

A canal to Clones would be 13 km long and, according to WI’s final restoration plan [PDF], would have one double lock (staircase pair). Some dredging would be needed on the River Finn and a new canal 0.6 km long would have to be provided; the work at the Finn end would cost €8.5 million altogether. On the line as a whole, work would be required on up to 17 bridges, some major and some minor or private bridges. And there would be a cost for land acquisition, although the Updated Economic Appraisal put that at a mere £1,268,280, a very small portion of the total cost. And then there would be the pumps and pipes to take water from the Erne, pump it to Clones and let it flow back down; it is not clear whether WI would have to pay for the water. And the total cost of this lot would be €38m + VAT, which I am told is about €45 million altogether.

Now, even allowing for the facts that there had been some voluntary and FÁS scheme work on the Royal, that no land had to be acquired and that parts of the canal were in water, I still find it difficult to see how a 13 km canal with one double lock can cost more than a 146 km canal with 46 locks. I have asked WI for a comment, but perhaps readers — especially if any of them are engineers or accountants — would be able to help to explain the mystery. Maybe it’s something simple like a mistake in the figures or maybe I’m missing something about the nature of restorations …. Enlightenment welcome.

 

Killaloe bridge

More on the new bridge here with the full public notice here [PDF]. Interesting to see how many of the names of landowners are known to me.

I see on page 6 of the notice that the ESB owns two rivers, which are occupied by the ESB, Waterways Ireland, the Inland Waterways Association of Ireland and other unknown persons. There is a canal, whose owners are unknown, which is occupied by WI, IWAI and the persons unknown, as is an island. I do hope that the council will return the canal, rivers and island when they’ve built the bridge.

Nice to see they’re going to get a Discover Day.

Prothero on the Armagh Blackwater and the Ulster Canal

Another extract from F E Prothero and W A Clark eds A New Oarsman’s Guide to the Rivers and Canals of Great Britain and Ireland: Cruising Club Manual, George Philip & Son, London 1896. The lack of detail suggests to me that Prothero did not travel this route himself.

Portarlington and Mountmellick

I have added some photos and maps to the page about the Mountmellick Line of the Grand Canal. Thanks to Martin O’Shea for two of the photos.

Limerick bridge

Just as Killaloe is to have a new bridge, so too is Limerick. Or perhaps more than one …. This page (on a site whose ownership I do not know) has a map of proposed routes for the proposed Limerick Northern Distributor Road, which is to provide a northern bypass of Limerick. You can read about it on the websites of the promoters, Limerick County Council, Clare County Council and Limerick City Council. You can download stuff. And you will be pleased to hear that there are to be consultations (only not many of them).

This road is to be built in two phases, the first covering the area from west of the city to Parteen and the second from there to the old Dublin road (N7 as was, now demoted to the status of boreen). There are (or were) several options for each section, but the decision to cross the navigation at the Ardnacrusha tailrace, between the power station and the existing bridge, seems to be set in, er, concrete: that is, it seems, where the ESB wants it.

Ardnacrusha and the tailrace seen from the existing bridge at Parteen

The current consultation is about Phase 2, south-east from Parteen. There are several possible routes.

Two of them, B1 and B2, would cross the Shannon downstream of Plassey and the Black Bridge; they would not cross the Plassey–Errina Canal. It would be important to ensure that they did not further damage the towing-path and its artefacts on the Limerick side.

The west bank below Plassey

Four other routes — C1, D1, D2 and E1 — would cross the Plassey–Errina Canal between Gillogue and Wooden Bridge; they would cross the non-navigable Shannon upstream of Plassey, between there and a point just above the confluence of the Mulcair. C1 seems to run very close to Gillogue Lock, although that may be an effect of the scale of the route markings.

Woodenbridge (which isn't)

I am sure that the ESB will look after the interests of the existing navigation (through Ardnacrusha) and that Waterways Ireland will look after those of the former navigation (the river to Plassey and the canal thence to Errina). However, it might be worthwhile lobbing in a comment to TPTB, first to sttress the heritage value of the abandoned navigation and second to suggest that a new road near Plassey might improve rather than diminish access to that area.

One final thought: this new road seems likely to put the final nail in the coffin of the Limerick Tunnel under the Shannon estuary downstream of Limerick. I very much enjoy using the tunnel, but many folk are deterred by the charges and they drive through the city instead — or, worse, cross the Shannon at O’Briensbridge. As a result, revenue is less than expected, so the traffic guarantee mechanism means that the National Roads Authority has to compensate the tunnel operators.

So now that a new, free, presumably fast road is to link the east and west sides of the city, what will happen to the numbers of vehicles using the tunnel and to the taxpayers who are ultimately paying the compensation? They’ll pay more. The tunnel is on a national primary route, so it’s the NRA’s problem, whereas the new bypass is a regional or local route, which is in the hands of the local authorities.

Russells of Portarlington, timber merchants

I am indebted to Eleanor Russell for permission to reproduce four photos of the canal operations of Messrs Russells of Portarlington, timber merchants and sawmills operators. They used the Royal and Grand Canals (and the Barrow Line and Mountmellick Branch) to carry timber cut on large estates to their sawmills. One of the estates on which they cut timber was Rockville, and Eleanor Russell has also given me permission to use a photo of Rockville House, taken in 1913, on my page about the Rockville Navigations.

Annoying the neighbours

It would be unfair to condemn the proposed opening of a canal to Clones without also condemning the proposed reopening of the Park Canal in Limerick (and the Newry, when I get around to it). The link is to a top-level page; the first substantive page has a lead to the second, the second to the third and so on up to the fifth.
