How are the roads today?

There is a version of this question you can answer before you look at anything, because Nairobi repeats itself. And there is a version you cannot, because today is not every day. Below: both, and how Rada’s founder checks.

From my reporting log

28 of my reports fit this guide, 4 May to 17 August 2026.

Roads they were on

  • Thika Road8
  • Eastern Bypass5

What I saw

  • Congestion9
  • Roadwork7
  • Accident6
  • Hazard4
  • Roadside activity2

Only my own reports are counted, from the Rada app. Places with fewer than two reports are left out. Road data © OpenStreetMap contributors.

What I’ve seen

Of my 28 reports, 8 are on Thika Road and 5 on the Eastern Bypass, more than on any other road.

Honestly, before I leave I check WhatsApp groups and any news on Twitter.

Some things you cannot plan for. Once, an NTSA crackdown on the Eastern Bypass, checking insurance and unroadworthy vehicles, caused heavy traffic. These things are hard to predict.

What a normal Nairobi weekday looks like

Most of Nairobi's main roads are spokes running in towards the same small city centre, so the morning peak is overwhelmingly inbound and the evening runs outbound. If you are travelling against that flow, your side of the road is often close to empty at the exact hour the other side is stationary.

Typical Nairobi congestion windows on a weekday
WindowDirectionWhat it looks like
Before 6amInboundStill moving. The hour people get up early for.
6–9amInboundThe peak. School runs and the working day start together, and the roads coming into the city are the worst.
MiddayBothA lunchtime bump around the CBD and the big office parks.
EveningOutboundThe long one.

Two roads break that pattern and are worth knowing about. Outer Ring Road runs across the spokes rather than along one, so it is busy in both directions in both peaks. Jogoo Road has one of the hardest mornings in the city, because it carries so many matatu commuters who leave early to be sure of a seat.

What makes today different from a normal day

When the roads are worse than the table above suggests, it is usually one of these:

  • Rain: the biggest factor by far. It slows everything, and you can expect the underpasses and the low-lying entries into the CBD to flood first.
  • School opening and closing days: the worst mornings of the year on Ngong Road and the other school-heavy routes. During the holidays the same roads are noticeably lighter.
  • Month end and the days after payday: more traffic in general, and noticeably more around the malls and the CBD.
  • Public holidays and the Friday before a long weekend: the outbound roads, especially Mombasa Road and Langata Road, can queue for much of the day rather than just the evening.
  • Police and NTSA checks: a crackdown checking insurance and roadworthiness slows everyone passing, not just the vehicles pulled over.
  • Events and processions: matches, marathons, concerts and demonstrations. Road closures for these are sometimes announced and sometimes not.
  • A single incident in the wrong place: one lorry stopped at a junction that everything funnels through, such as Allsops, Galleria or Taj Mall, can undo an otherwise normal day across a whole side of the city.

How to check your own road before you leave

A map app will tell you a road is red. That is genuinely useful, and it is also where it stops. It will not tell you why it is red, and it will not tell you whether it is about to clear or about to get worse, which is usually the thing that decides what you do.

The three questions worth answering before you pick up your keys:

  • Is this normal for the time? Check the table above. If it is the peak, it is probably just the peak.
  • Has it rained, or is it about to? This overrides everything else.
  • Has anyone reported something on my actual route? Not the city in general. The road you are about to drive.

That last one is what Rada is built for. You save the roads you use, and you get a notification when another driver reports an accident, a closure, roadwork or a hazard on one of them, with a running thread underneath saying whether it has cleared.

Road by road

Each of these covers one road's own pattern, its named bottlenecks in order, and the alternatives that genuinely help:

Quick answers

A map app will show you which roads are red, which is a good first look. For why a road is red and whether it is clearing, you need people who are actually there. Rada sends you a notification when a driver reports an incident on a road you have saved, and keeps a thread on it so you can see whether it has cleared.
Inbound, from about 6 to 9am, and the roads coming into the city, such as Thika Road and Jogoo Road, are the worst. Outbound, through the evening.
Underpasses go first, followed by the low-lying approaches into the CBD. Any road that is unpaved or currently dug up for works becomes far worse than merely slow. Heavy rain slows almost every journey.
The general map apps show live congestion colours for Nairobi. What they do not carry is the reason behind the colour or whether it is improving. Rada covers that second part through drivers reporting on the roads they are on, rather than through a map.
Three things help more than any route trick. Travel against the flow where your day allows it, since the opposite carriageway is often near empty. Use the bypasses if you are not actually going into the CBD. And move your departure time rather than your route, because leaving earlier frequently beats any alternative road.
