Chapman’s Peak Drive will undergo scheduled exploratory engineering work during March 2026 to support ongoing safety assessments and long-term infrastructure planning along the route.
The work requires temporary road closures on the following dates:
- Wednesday, 11 March 2026 – Half-width road closure from 08h00 to 17h00 [Stop & Go in place]
- Wednesday, 18 March 2026 – Full road closure from 08h00 to 17h00
- Wednesday, 25 March 2026 – Full road closure from 08h00 to 17h00
These investigations form part of Chapman’s Peak Drive’s continuous programme of geotechnical monitoring, slope assessment and infrastructure planning to ensure the long-term safety and accessibility of this iconic coastal route.
Why This Work Is Necessary
Constructed along steep cliffs between Hout Bay and Noordhoek, Chapman’s Peak Drive has always required specialised engineering to manage the natural environment in which it sits. From its original construction in the early 1900s through to the major upgrades completed in 2003, the drive has combined historic engineering ingenuity with modern safety systems.
As outlined in our Engineering section, the road was built along a natural granite contour within a complex geological environment where rockfalls and slope instability can occur. Modern engineering solutions — including rockfall catch fences, protective canopies, and advanced terrain modelling—have been implemented to predict and manage these natural hazards.
Exploratory testing such as drilling and geotechnical sampling allows engineers to assess the condition of the mountain slopes above the roadway and evaluate future infrastructure requirements. This type of work is common on cliff-side scenic routes around the world, where regular monitoring and preventative maintenance are essential to maintaining safe public access.
A Legacy of Engineering Excellence
Since its official opening in 1922, Chapman’s Peak Drive has become not only one of the world’s most scenic drives but also a showcase of South African engineering. Following extensive safety upgrades and reconstruction, the route reopened in 2003 with advanced rockfall protection systems designed through sophisticated terrain modelling and hazard analysis.

Planning Your Journey
Motorists are encouraged to plan their travel around these closure periods and to make use of alternative routes between Hout Bay and Noordhoek where necessary.
While temporary closures may cause short-term inconvenience, these investigations form an important part of ensuring that Chapman’s Peak Drive remains safe, accessible and sustainable for future generations of road users, visitors and cyclists who enjoy this world-renowned coastal drive.
We appreciate your patience and understanding while this essential work is undertaken.
