Riding the Nairobi Expressway: A Visitor's Practical Guide

What the Expressway is and why you'd use it

The Nairobi Expressway is a 27-kilometre toll road that runs above Mombasa Road from Mlolongo in the east to James Gichuru Road in the west, passing over the Southern Bypass, Nyayo Stadium and the central business district. For visitors, its main value is bypassing the notorious congestion on Mombasa Road and Uhuru Highway, especially between the Jomo Kenyatta International Airport (JKIA) and Westlands or Parklands. A trip that can take two hours in rush hour may take 25 minutes on the Expressway.

Tolls are distance-based and paid via electronic tag or cash at the plaza. Rates change, so check the official website before you travel. The road is open 24 hours, well-lit and patrolled. It is not a scenic route—you are on an elevated concrete deck—but it is reliable. If your hotel is in Westlands, Parklands or along Waiyaki Way, the Expressway is usually the fastest way in from JKIA.

Entry and exit points that matter to visitors

The most useful entries for travellers are at JKIA (follow signs from the airport), Mlolongo (for the SGR train station) and the Southern Bypass (for Wilson Airport or Langata). Exits are at Capital Centre (for Upper Hill and Kilimani), Haile Selassie Avenue (for the CBD and Upper Hill), and James Gichuru Road (for Westlands, Parklands and Lavington). Each exit drops you onto a specific road, so know your hotel's neighbourhood before you set off.

For a hotel in Westlands, use the James Gichuru exit; for Kilimani or Upper Hill, the Capital Centre exit is more direct. If you are staying in Karen or Langata, the Expressway is less useful—the Southern Bypass is often quicker. Note that the Expressway does not connect directly to the Northern Bypass or Thika Road, so for Gigiri or the UN complex, you are better off using Limuru Road or the Northern Bypass from the west.

Costs, payment and practical tips

Tolls are paid at plazas along the route. You can pay cash (Kenyan shillings) or use an electronic tag, which you can obtain at customer service centres at the plazas. For a short stay, cash is simpler; for frequent trips, a tag saves time. Rates depend on the distance and vehicle class, so check current prices on the official Expressway website. As a guide, a car trip from JKIA to Westlands typically costs a few hundred shillings—less than a taxi fare, but you are paying for the time saved.

Avoid the Expressway during peak hours (7–9am and 5–7pm) if you can, as the entry and exit plazas can queue. Outside those times, it is usually clear. The speed limit is 80 km/h and enforced by cameras. Keep your payment ready, follow lane signs, and do not stop on the shoulder. If you are renting a car, confirm with the hire company whether the vehicle has a tag and who pays tolls.

Where to stay to make the most of it

Westlands and Parklands are the most convenient areas for Expressway users: the James Gichuru exit puts you on Waiyaki Way, minutes from hotels like the Sarova Panafric (actually on Kenyatta Avenue, but close to the Expressway) or the many options along Rhapta Road. For a mid-range stay, expect $80–150 per night; upscale hotels run $150–300. Kilimani and Upper Hill are also good, with the Capital Centre exit giving quick access to Upper Hill's business hotels and Kilimani's apart-hotels.

I would book in Westlands if you plan to use the Expressway often: it is close to the James Gichuru exit, has plenty of restaurants and shops, and is a short drive from the Nairobi National Museum and Karura Forest. Skip hotels in the CBD unless you have business there—traffic on Haile Selassie Avenue can be heavy, and the Expressway exit there is often congested. Also skip Karen unless you have a car and plan to explore the western parks.
