For years, Gauteng's e-toll gantries were among the most visible symbols of a system that never gained public support. Stretching across the province's major highways, the structures became a reminder of a tolling scheme that many motorists simply refused to pay for.

With the e-toll system now officially scrapped and historic debt written off, attention has shifted to a different question: what happens to the infrastructure left behind?

Rather than removing the gantries, authorities plan to put them to work.

Transport Minister Barbara Creecy recently confirmed that the South African National Roads Agency (SANRAL) and the Gauteng Provincial Government are exploring ways to repurpose the network for road safety and law enforcement functions.

Measuring Speed Differently

One of the main proposals is to use the existing gantries for an Average Speed Over Distance (ASOD) system.

Unlike traditional speed cameras that record a vehicle's speed at a single point, ASOD technology measures how long it takes a vehicle to travel between two locations. The system then calculates the average speed over that distance.

Supporters argue that this approach encourages more consistent driving behaviour because motorists remain aware that their speed is being monitored over an extended stretch of road rather than at one specific location.

The proposed network would cover sections of Gauteng's busiest routes, including parts of the N1, N3, N12 and R21.

More Than Speed Enforcement

The plans extend beyond monitoring speed.

Authorities are also investigating ways to use the gantries as part of broader vehicle tracking and road management systems.

Potential uses include:

• Identifying stolen vehicles through number plate recognition technology.
• Detecting cloned registration plates linked to criminal activity.
• Monitoring overloaded freight vehicles that contribute to road deterioration.
• Supporting vehicle licensing and registration verification systems.

If implemented, the technology could allow authorities to respond more quickly to stolen vehicle alerts and improve enforcement against overloaded trucks operating on major routes.

A Growing Focus on Smart Road Technology

Gauteng is not the only province looking at technology-driven traffic management.

In Cape Town, authorities have introduced electronic speed display signs that show motorists their current speed and encourage them to slow down when exceeding the limit. Similar systems have been adopted internationally as a way of promoting compliance without relying solely on fines and penalties.

Worth Watching

The future of Gauteng's e-toll gantries is still being shaped, but one thing is clear: the structures are unlikely to disappear anytime soon.

For motorists who spent years viewing them as symbols of an unpopular tolling system, their next chapter could look very different. Whether the technology delivers safer roads and better enforcement will ultimately depend on how effectively it is implemented and managed.
