I was born in Cape Town.  There are many sights that are the pride and joy of the Mother City, and its environs.  Linda and I drove the scenic Chapman’s Peak Drive today.  I planned to do research but found this perfect website below.  I copied and pasted its content below.  The editing was to Americanize the spelling and insert comments to clarify terms from Afrikaans and to update currency to today’s figures.  The video is 15 minutes in length.  Near the halfway mark, you will see the major engineering work that added safety to the road.  Along the drive observe the fencing used to catch rocks that may fall from above.  Linda and I have driven portions of the scenic Pacific Coast Highway in California, yet the much shorter Chapman’s Peak Drive has a beauty of its own.  As you read the detail below, it is fascinating to understand the number of challenges that needed addressing over the years prior to taking this leisurely drive..

The website linked above provides traveler information such as current weather and road conditions, toll rates, and status if the drive is open, etc. Its historical content is published below with minor editing.

!5 minutes of scenic beauty and an engineering marvel.
As you watch, imagine the feat of creating a road out of the side of a mountain.

Chapman’s Peak is named after John Chapman, the Captain’s mate of an English ship, the Consent. The peak, which looms overhead, was not named after a governor or brave mountaineer, but a lowly ship’s pilot. In 1607 the skipper of the British ship Contest found his vessel becalmed in what is now Hout Bay (wood bay) and sent his pilot, John Chapman, to row ashore in the hope of finding provisions. The pilot later recorded the bay as Chapman’s Chaunce (chance) and the name stuck, becoming official on all East India charts.

In the early 1920’s Sir Nicolas Fredrick de Waal, first administrator of the Cape Province, ordered the construction of a high-level road linking Cape Town with the Southern Suburbs. The roadway (De Waal Drive) was extremely well received. Enthused with the success he called for another road linking Hout Bay to Noordhoek (north corner). Two possible routes were under consideration in 1910. The route over the low neck between the Chapman’s and Noordhoek Peaks was second to the more spectacular route along the vertical sea cliffs.

In 1914 preliminary surveys on the road got underway. Surveying the route was a scary business. The cliffs and ravines were steep, rotten and unstable, and at times the surveying party was on all fours as they investigated the perpendicular terrain. The route over the neck appeared to be no better, and the project appeared to be expensive and a ‘mission impossible’. De Waal however, would not take no for an answer and eventually he ordered the ‘go ahead’ for along the cliffs which appeared, at the time to be the better option.

The road was cleverly planned with the road surface based on the solid and conveniently located 630 million-year-old Cape Granite contour, while the many roadside cuttings would be carved out of the more workable Malmesbury series sediments.

In 1915, with the use of convict labor supplied by the newly formed Union Government, construction began from the Hout Bay end, and in the following year, work began from Noordhoek. The first portion of the road to the Lookout was opened in 1919.

This spectacular roadway took seven years to complete, at a cost of ₤20 000. (₤100 million in today’s currency, or US$130 million).  The Hout Bay – Noordhoek Road ‘hewn out of the stone face of Sheer Mountain’ was opened to traffic on Saturday 6 May 1922 by the Governor of the Union of South Africa, His Royal Highness Prince Arthur of Connaught.

In 1962 a section of the road was widened, and in 1977 a portion of road was washed away, and subsequently the road was closed on 14 May, after a large section was washed away and the damaged section was replaced by a bridge at a cost of R150 000 (R5.5 million in today’s money or US$ 400,000).

Road Closure in 2000

In 1994, Noel Graham was injured and partially paralyzed in a landslide incident on Chapman’s Peak Drive, which resulted in a court case against the Cape Metropolitan Council who was the road management agent at the time of the incident. In February 1999, a High Court judgment was given against CMC for negligence in the management of the road. The matter was appealed by the CMC but the Supreme Court dismissed the appeal in November 2000, thus reaffirming the Cape High Court’s decision, and CMC was ordered to pay all claims and costs.

Amidst increasing concern for public safety and legal liability, the South Peninsula Municipality (SPM) – the new road management agent appointed in 1997, established a sub-committee of officials from the local, metropolitan and provincial authorities to guide the management of Chapman’s Peak Drive, who instigated high visibility rock fall warning signs to be erected on Chapman’s Peak Drive during 1999. The sub-committee also adopted a specific Chapman’s Peak Drive closure policy which inter alia stipulated that the road had to be closed to traffic in rainy weather (very light drizzle excluded) and remain closed for a number of hours after cessation of any rainfall and until deemed safe by SPM’s road management staff. This closure policy/procedure was implemented by SPM’s road management staff with lockable booms put in place to prevent unauthorized entry.

On 29 December 1999 however, a falling rock caused the unfortunate death of a Noordhoek resident. In early January 2000, Ms. Lara Callige was killed, and a passenger in the same car seriously injured in a rock fall incident on Chapman’s Peak Drive in good weather conditions when the rock fall risk on the road was not considered to be high. This was of serious concern to the local and provincial authorities alike and emergency meetings to discuss the closure of Chapman’s Peak Drive were held between the relevant political bodies. Before a decision could be taken on the matter, and still in January 2000, the worst mountain fires in many decades raged in the Cape Peninsula, including in the mountains above Chapman’s Peak Drive, causing numerous rock falls onto the road and effectively rendering the road impassable.

Because of these incidents, Chapman’s Peak Drive was officially closed to traffic indefinitely by the Provincial Minister of Transport in January 2000.

Development 2000 – 2003

Based on the recommendations of geotechnical specialists, the Provincial Administration’s Transport Branch made available funding for “rock barring” (a term used for removing loose or dangerous rocks) of the mountain slopes above the road to make them safer. Contracts for this work were awarded in March 2000 by the SPM.

It soon became apparent that the rock barring process deemed would take substantially longer than originally anticipated and cost commensurately more. The work was thus stopped in May 2000 and an integrated environmental management process (IEM) was put in place with the goal of producing an agreed management plan for Chapman’s Peak Drive by mid-2001. The IEM process brief required management to include:

  1. the improvements deemed necessary to make the road safe for users,
  2. a strategy for managing/operating the road,
  3. recommendations on funding sources for capital improvements as well as the continuing operational needs.

At the end of April 2001 the IEM process had included:

  1. A review of the initial “rock barring” work which concluded that some rock barring may be necessary for the final upgrading process, but the “clean sweep” approach could not be condoned and the selective rock barring also would have to be accompanied by various engineered rock fall protective measures in order to make the road safe for users.
  2. A comprehensive stakeholder workshop in September 2000, which identified and agreed to various improvements and protective measures, which needed to be implemented on Chapman’s Peak Drive with the overriding and urgent requirement to re-open the road to traffic as soon as possible being supported by all participants.
  3. A detailed site survey of the road itself and mountainside above and below the road to facilitate a concept design proposal (areas covered by rock and the time had to be omitted).
  4. Completion of various concept design proposals incorporating some or all of the following elements: rock barring, catch fences, rock gallery protection, concrete roof protection, existing structure repair, road surface, and layer work repair, slope stabilization work above and below the road, etc.
  5. Public meetings were held in late November 2000 to present the status of the project to the general public in the Hout Bay and Noordhoek Valley areas and obtain relevant feedback from interested and affected parties, and further meetings in March 2001 presented the progress on the project.

The IEM process was guided by a project management team consisting of officials from the Provincial Administration, Western Cape, and officials from the City of Cape Town’s South Peninsula and CMC administrations.

Public-Private Partnership (PPP)

The legal road authority for Chapman’s Peak Drive is the Provincial Administration Western Cape (PAWC) realized early on in 2000 that financial limitations would be the single biggest stumbling block to the safe re-opening of Chapman’s Peak Drive to traffic. To solve these financial problems the plan was to implement a public-private partnership and proclaim the route a Toll Road under the Western Cape Provincial Toll Road Act. The feasibility study concluded that the majority of the costs attached to the Chapman’s Peak Drive reopening and operation could be obtained through tolling the road and that a public-private partnership with a concessionaire demonstrated value for money in terms of the risks transferred to the private sector.

The Chapman’s Peak Engineering Group Joint Venture was awarded the tender after being shortlisted and the project was overseen by Entilini concessions – the special-purpose company established by the consortium of Concor Holdings, Haw & Inglis and Marib Holdings.

The Joint Venture included Vela VKE Consulting Engineers, Meli & Du Plessis Geotechnical Engineers, Stewart Scott International, Zietsman Lloyd Hemsted and assisted by Megan Anderson Landscape Architect (environmentalist); OvP& Associates (landscape architect); Dr. Ross Party-Davies (geotechnical specialist) and Prof Rolf Kratz (structural design specialist).

Due to its sensitive location within the Table Mountain National Park, an integrated environmental approach to the rehabilitation and upgrading of Chapman’s Peak Drive was required. See details on the engineering page of work that was undertaken to ensure that rock fall protection measures were put in place along with an advanced traffic management system.

2003 – Present

After intensive design and reconstruction, Chapman’s Peak Drive was re-opened to traffic as a toll road on 20 December 2003. The opening was a welcome return for the drive as an “international tourist destination” complementing other tourist destinations in the Western Cape. Local businesses also welcomed the re-opening.

The new rock fall measures were however put to the test, and during July and August of 2004, three rainfall incidents occurred of extremely high intensity. A total of 396mm was recorded in the 2 months, compared to the mean annual precipitation for the area of 740mm! Shortly thereafter several debris slides and rock fall incidents occurred, resulting in damage to the catch fences and Chapman’s Peak Drive was closed for 55 days to clear the debris and replace the 4 catch fences.

The much-loved road was back in the news when Chapman’s Peak Drive was once again declared unsafe for road users in June 2008 and the drive was closed for major upgrades and repairs. The construction work took over a year and was eventually re-opened on the 9th of October 2009. Chapman’s Peak Drive has remained open since then, albeit with temporary closures for routine maintenance and during dangerous weather conditions.
