The Lapal Canal Project
The Lapal Canal is the eastern half of the Dudley No. 2 Canal in the UK West Midlands
 


The Lapal Canal :
Brummagem's forgotten Bypass

Over two hundred years ago, Birmingham was already so important it needed a bypass !

It was the dawn of the Industrial Revolution; the heyday of the canal era and the waterways in the West Midlands were fast becoming the hub of the entire UK system. Not surprisingly, with almost all raw materials and manufactured goods being transported by sturdy and reliable narrow-boat, the Birmingham Canal Navigations (the BCN, as they are now known) soon fell victim to their own success and became heavily congested. In particular, this congestion impeded the otherwise steady and highly-lucrative movement of coal from the abundant supplies in the Black Country, on their long-haul journey South to fuel the fires of residential London. As a first major conflict in modern domestic economics, this could not be tolerated ! (map-link)
So, with great haste, the Dudley No. 2 Canal was surveyed, constructed and then opened in 1798 for more than a century of strategic operation until it fell victim to some of the defects of its hurried construction. But, having been disused and almost forgotten for over half a century, it now awaits sympathetic restoration using modern engineering solutions.


The Dudley No. 2 :
the hasty construction of a speedy solution

The original purpose of this canal was to provide as direct as possible, a connection between the Dudley No. 1; already in use around the local Black-Country coal measures, and the major Southern waterways.

  These are the Worcester & Birmingham (W&B); linking to the south-west for export shipping, and the Grand Union; linking to the domestic markets of London and the Home Counties. For these links to operate properly, the canal had to be a level waterway with no time-consuming, level-changing locks. The chosen contour route resulted in an 11-mile waterway which was opened in 1798 and took a, then, rural meander from Windmill End in Netherton, south to Halesowen where it turned east to join the W&B in Selly Oak.

In the latter half of the route it had to overcome two major obstacles, one of which was the valley which is now part of Leasowes Park. The traversal of this was achieved in a 60ft high earthen embankment; the first of its kind to be constructed. The second, even more exacting obstacle, was the elevated plateau that is now the Woodgate Valley parkland. The traversal of this was achieved through a tunnel with its eastern portal in the California district of south-west Birmingham and its western portal in the Lapal district of Halesowen; a monumental 2.2 miles or 3,795 yards apart.


The early demise :
an unexpected fault

As the fourth longest in the UK, the Lapal Tunnel passed through a geological Fault (about where the M5 is now) and suffered an unfortunate series of roof-falls which blocked it, from time to time, with localised heaps of running sand. The last of these, way back in 1917, was too costly to repair so the tunnel was abandoned and full navigation ceased. Inevitably, the approach waterways, either side of the tunnel, also fell into gradual disuse and were finally decommissioned in 1953.

What remains today is still a tranquil western half canal which passes  from  its Park Head junction with the Dudley No. 1, via Lapal's "little sister" tunnel under Gorsty Hill to end at the delightfully picturesque Hawne Basin.

For many of the recent operational years until 1967, this basin was a major rail-canal interchange which further justified the continuing service of the western half. But beyond that the eastern half; now the Lapal Canal, is almost completely dry and filled-in for safety's sake. Yet, in many ways, this amounts to "good news" for having cocooned the canal for the day when modern methods can be used to rebuild it to a lasting specification.


The Lapal Canal Trust :
Tunnel Vision

The restoration potential for the Lapal canal was formally identified in 1990 when a group of inland waterway enthusiasts formed the Lapal Canal Trust (LCT). Their initiating and persistent vision was that the use of modern engineering methods and materials makes it entirely feasible to reclaim this missing link between Hawne Basin and  Selly Oak, via the long-disused but hugely-intriguing Lapal Tunnel. Furthermore, the Lapal restoration project is unique in having two heritage sites very near to the canal, at either end of the tunnel, which would also benefit from revived and improved access.


Restoration Benefits :
the Lapal Greenway

Restoration brings a wealth of benefits to the communities which surround or make use of canals. For the Lapal Canal the principal benefits of the resulting Greenway are;

- Recreational amenity for walkers, joggers, cyclists and anglers

- Corridor and haven for rural wildlife in urban settings

- Rejuvenation of two heritage sites; Halesowen Abbey and Weoley Castle

- Additional boating opportunities for canal tourism  (i.e. further cruising 'rings' around the Midlands)

Restoration Strategy :
to Make Ends Meet

The 5.4 miles long Lapal project conveniently divides into three distinct components;
  - The Halesowen or Western Approach canal
   - 1.4 miles, 2195 yards

- The Lapal Tunnel - 2.2 miles, 3795 yards

- The Selly Oak Extension or Eastern Approach canal
   - 1.8 miles, 3146 yards

In practice, the restoration of the two Approaches will deliver most of the Greenway benefits to their respective communities. Therefore, the Tunnel may be deferred until sufficient funds allow for its restoration to occur as a single, complete project.


Restoration Sequences : 
the parallel 'thirds'.

Leaving the Tunnel until last allows for concentration on the two Approaches to achieve the more immediate and tangible benefits of restoration. Taken in order, away from their respective junctions with existing waterways, both of these lengths further divide into three sections. This results in a restoration sequence of paired projects, each of which may become an individually-scheduled, stand-alone project within a budget plan. Schematically, they are;

Lapal West
<- 1.4 Miles ->
Halesowen Restoration
Lapal Tunnel
<- 2.2 Miles ->
Lapal East
<-1.8 Miles ->
Birmingham Restoration
The Leasowes Abbeyfields St Mary's
Parkland Backland Meander Heritage Flank
500 yards 375 yards 1320 yards
 
3795 yards
Weoley Castle Lodge Hill Selly Oak Park
Heritage Flank Backland Meander Parkland
894 yards 1273 yards 911 yards

Restoration of the first two flanks at either end, provides immediate benefit to the communities in each district by enhancing the parkland with a water-feature. The presence of additional wildlife and the occasional boat on these short 'cul-de-sac' restorations, sets the scene for the remaining Lapal canal and its accompanying Greenway. Then the backland-meanders establish the full Greenway corridor by substantially extending the two 'cul-de-sacs' towards the tunnel. In both cases, there are additional requirements for intermediate bridges to be constructed across these sections to maintain footpaths which have become established since closure. Finally, the two heritage-flanks are each accompanied by imaginative plans in which partnerships may deliver an integrated restoration and conservation, both for the canal itself and for the heritage site nearby. In both cases, there is uncommitted land which could be drawn in to elaborate schemes which combine old heritage with new amenity. Then, once these major potentials have all been realised, a re-engineered Lapal Tunnel will link them together as the scheme's final crowning glory.


St Mary's across the A456 :
an aqueduct?

With the construction of the M5 motorway near Halesowen,  the transformation of the once narrow Manor Lane into the present A456 Manor Way dual-carriageway, imposed a major severance on the canal. Originally, it crossed alongside the Black Horse pub (in, now, its lower car-park) and then meandered South towards the fish-ponds of St Mary's Abbey before turning East to the tunnel portal in Lapal. Unfortunately, the required water-level for the restored canal is now in direct conflict with the A456 gradient if it was to be reinstated at its former crossing by the pub. However, on the South side, a rectangle of open rural land can be identified between the pub, an open-cast mine to the west, St Mary's Abbey to the south and the fish ponds. If the canal was to cross the A456 in the vicinity of the mine (some 150 yards west of the pub) the A456 gradient makes it sufficiently lower at this point, for the canal to traverse in an aqueduct. This could be one of an impressive, ultra-modern design and amongst its several benefits, its towpath-walkway would provide a much-needed, safe pedestrian crossing over the A456. Thus, as the parcel of rural land becomes reconnected, so a series of other improvements can be considered. For example, the Black Horse could be reconstructed and elevated to the status of a full hotel, accompanied by extensive moorings (in the old canal channel) as a focus for recreational activities in this pleasant rural setting.


The Weoley Castle Flank :
 a boat moat?

In the district of Weoley Castle where the canal passes close by the ruins of the 13th Century manor house of that name, there is a triangular parcel of land which also offers huge potential. Its apex lies to the east, where the Stonehouse Brook crosses the canal in a former culvert, and its base is to the west, embracing the California common land (with the former tunnel portal buried beneath). In principle, this triangle affords a realistic opportunity for the expansive creation of a range of amenities which may include some or all, of the following;

- a canal-connected moat for the Ruins, with swing-bridge to legitimise access
- a visitor centre; over-seeing the Ruins
- a pub and restaurant; over-looking the Ruins
- a community centre with sports, leisure and youth facilities
- a marina (in the vicinity of the former road stone premises)
- diversion of Stonehouse Brook water into the canal to add to the entire BCN

This is a second example where restoration of the Lapal Canal could trigger a range of additional and timely developments to benefit the local community over and above the mere return of (for them) a short stretch of water!


The Lapal Tunnel :
a subterranean canal museum?

Even in its operational period, the Lapal Tunnel was a narrow-bore tube just suitable for one-way working at a time, by the, then, familiar practice of legging.


The former central ventilation air-shaft.

It was little more than a long and eerie drain-pipe which would not meet today's Health & Safety considerations. Therefore, it is proposed to replace whatever remains of the tunnel with one of modern construction that is wide enough for bi-directional working and includes an escape walkway and service duct. This could be done by using the old tunnel as a "pilot-hole" and drilling along it (or alongside it) using engineering methods similar to those which created the Channel Tunnel.

Of course, the resulting tunnel would have none of the historical authenticity of the original, so there is an ambitious proposal to exploit to full effect, its ultra-modern contrast with the past. The centre of the Lapal Tunnel and the site of its former ventilation shaft now lies near the rear of the Woodgate Valley Visitor Centre. At that point the Tunnel's water level is approximately 60ft below ground. The suggestion is to form a link down to the new tunnel and create a "huge" underground cylindrical cavern with a glass dome roof and internal floors beneath of ultra-modern construction (e.g. metal-glass). The rooms on the uppermost, ground-level floor would serve as the replacement Visitor Centre while the lower, subterranean floors would house the Canal Museum which many commentators believe Birmingham should have.
Finally, the water-level base of this construction would be a circular marina for boating visitors to have direct access to the Museum from beneath. With an imaginative design, the entire construction (the "Rotunda-Under"?) would have several aspects in common with the Cornish Eden Project, but in a prominent site in the West Midlands with the potential to be a unique and prestigious day-out tourist attraction for decades to come.

Considered all together, the two heritage sites if fully developed and then linked by a tunnel with a 'hidden' museum chamber, could elevate the Lapal Greenway into becoming a highly significant and fascinating recreational corridor with something-for-everyone appeal?


The Towpath :
a greenway to health

Meanwhile, in full contrast to these three grand yet highly-speculative projects, canal restoration also brings a series of almost-certain opportunities for smaller-scale enhancements. For full authenticity, modern restoration must include the sympathetic recovery of the towpath together with the reinstatement of former bridges, as the all-important provisions for the non-boating communities to enjoy the greenway corridor. For the Lapal restoration, it is proposed that the towpath will be re-instated to run predominantly along the southern (or western) flank. In addition, all surfaces will be wide and level or of a gentle gradient, so they remain friendly to the pedal cyclist, wheel-chair user and baby-carriage pusher, as well as the walker, jogger and runner. Particularly for this canal, its special proximity to the Queen Elizabeth Hospital complex also makes its eastern end a uniquely strategic corridor for rehabilitation excursions (via the W&B canal) during convalescence after medical treatment and appropriate provisions are also being proposed in this special context (e.g. benches at regular intervals).


Home Improvements :
Roses for Castles!

Also on the smaller-scale, there are benefits for the private householder. Authoritative studies, from restorations elsewhere in the UK, show that domestic-property values rise when an adjoining canal is restored, while some aspects of crime and social disruption fall significantly. Houses on the offside benefit from the totality of "moat security" allowing householders, if they wish, to remove their garden-end fences and replace them with water-side patios or floral gardens. Conversely, properties on the nearside benefit from the much-improved access afforded by the restored towpath which, in some cases, may be landscaped to be wide enough to allow vehicle access to rear-garden garages.

Imaginative landscaping of an offside garden.

(This would appear to be a particularly strong possibility along the Lodge Hill meander where a restoration detail of dual vertical sides (and towpath switch) requires less channel width than the former sloping-offside profile.)


Restoration Activities :
tin shakes and working parties.

Modern restoration methods invariably require the use of professional contractors so that a given project is undertaken properly and completely with a minimum of disruption to the adjoining community. In such cases, the role of the Lapal Canal Trust and its members is that of project liaison and fund-raising. However, all such projects are accompanied by preparatory work beforehand and then post-restoration conservation and maintenance activities which are delivered through working parties.

Typically, these utilize local and sometimes national volunteers and expertise - and are always great fun for the enthusiastic participant! Likewise, attendance at waterway meetings and festivals, and local events and fetes ensures that the aims of the project are made known to as wide a compass of interested parties as possible. These gatherings are great fun, too!


Wide Participation :
Individual and Corporate Membership

Since the days of its formation, the Lapal Canal Trust has established a solid membership of private individuals who have pledged themselves to the restoration and conservation of the Dudley No.2 Canal. From such people are drawn the Trust's Officers on a rotational and voluntary basis. Likewise, we have the interest and commitment of a variety of local industrial and commercial companies who also provide funds or facilities to help us during the pre-restoration activities and campaigns. If you, or the organisation you work for or have commitments to, are prepared to help us, we would be very pleased to hear from you.
