Sri Lanka Metro Bus Guide 2026: All Seven Colombo Routes (CM01–CM08), How to Pay, What It's Like, and Is It Useful for Visitors?

Lanka Metro Transit (Pvt) Ltd is a government-owned company operating under the Ministry of Transport, Highways and Urban Development. Its Cabinet approval came in 2025, and the Metro Bus programme was funded through the 2025 Budget.

The aim is to give people in Greater Colombo a public transport option comfortable enough to leave the car at home. Officials have specifically mentioned reducing the number of private vehicles entering Colombo with only one person inside.

The buses are air-conditioned and low-floor, with ramps for wheelchair users and dedicated priority seating. LMT says the fleet is Euro 6 standard, with CCTV, next-stop displays in English, Sinhala and Tamil, and live GPS tracking.

Each route has a 'CM' code and a colour. Routes run on fixed stops and schedules, rather than the stop-anywhere, leave-when-full approach of many private buses.

It is not a bus rapid transit system with separate lanes and stations along its whole length. Colombo has introduced priority bus lanes on some roads, but for most of their routes Metro buses share the road with everyone else.

21 April 2026: the pilot launched from the Makumbura Multimodal Centre with ten air-conditioned, low-floor buses designed for passengers with disabilities, on two routes — Makumbura to Colombo Fort and Makumbura to Kadawatha. The routes were planned to serve major hospitals, including Apeksha Hospital in Maharagama and the National Hospital in Colombo.

July 2026: a shipment of 104 new low-floor buses arrived at Colombo port, and refurbished low-floor buses arrived from Japan under a grant.

4 August 2026: Lanka Metro Transit published the seven-route network map, and the Cabinet approved 50 additional buses.

September 2026: new depots opened at Thalangama, Kadawatha and Ekala.

29 September 2026: the network expanded to seven routes. 112 new buses entered service — 104 under the Metro Bus programme and eight provided by the Government of Japan — bringing the fleet to 122.

These are the routes announced by Lanka Metro Transit, with distances from its official route presentation. Route endpoints and intermediate areas are as published; individual stops can change, so check the LMT GO app before you travel.

CM01 (Blue) — Makumbura to Pettah/Colombo Fort, 23.3 km, via Pannipitiya, Rajagiriya and Borella.

CM02 (Yellow) — Millennium City (Athurugiriya) to Colombo Fort/Pettah, 22.3 km, via Athurugiriya, Malabe and Borella.

CM03 (Indigo) — Kadawatha to Makumbura, 34.8 km. This descends from the original pilot route serving Apeksha Hospital, Nugegoda, Borella and Kiribathgoda.

CM04 (Orange) — Dematagoda to Panadura, 28.7 km, running south along the coast through areas including Dehiwala and Moratuwa.

CM05 (Purple) — Battaramulla (Thalangama depot) to Ekala, 29.9 km, with 21 stops including Sethsiripaya, Rajagiriya, Borella, Wattala, Kandana and Ja-Ela.

CM06 (Light Green) — Kollupitiya Circular Route, 14 km, a loop around central Colombo.

CM08 (Dark Green) — Kesbewa to Pettah, 35.7 km. One September report described this route as Kahathuduwa to Pettah/SLIIT; most reports and the official presentation use Kesbewa. Check the app.

There is no CM07 at present. The numbering suggests more routes are planned.

LMT promotes cashless travel. Its website describes two main methods: tapping an 'LMT Touch' card, or scanning a mobile QR ticket from the LMT GO app. The app is available on Google Play and the Apple App Store.

LMT describes its fares as 'transparent stage fares', meaning the fare depends on how far you travel, as on regular Sri Lankan buses.

Fare table: we could not find an official published fare table on LMT's website or in announcements at the time of writing. Check fares in the LMT GO app or ask the conductor.

Cash: reports from the April pilot said passengers could also pay the conductor in cash or by card. We could not confirm whether cash is accepted on every route after the expansion. If you do not have the app or a card, carry small notes and ask before boarding.

Where to get an LMT Touch card: we could not find published details. Ask at the Makumbura Multimodal Centre or on board.

For short-term visitors, the simplest approach is likely to be downloading LMT GO before your trip, then confirming payment options on your first ride.

LMT GO is the official Metro Bus app. LMT says it offers live GPS bus tracking, stop arrival alerts, audio announcements, digital passes and timetables.

LMT's website also has a live bus map and a journey planner where you choose an origin and destination stop.

Use only the official app and lankametro.lk. At least one unofficial website presents itself as an 'official' Metro Bus information hub, but uses route codes and timetables from the pilot phase that do not match the current network — for example, labelling the Makumbura to Colombo Fort service with a different CM number. Information on such sites may be out of date.

LMT's website advertises departures every 5 to 10 minutes during peak commuting hours. That is the operator's stated target; we have not measured it, and the network has only just expanded.

Operating hours for each route were not published in a form we could verify. On the pilot Makumbura to Colombo Fort route, the first morning departure was reported at 5.30 am, but timetables may have changed with the expansion.

Journey times depend heavily on traffic. A full run on the longer routes, such as Makumbura to Kadawatha or Kesbewa to Pettah, can take well over an hour at busy times.

Check live arrivals in LMT GO rather than relying on fixed times.

Accessibility is where the Metro Bus is genuinely different from almost every other bus in Sri Lanka.

The service began as an accessible pilot. The buses are low-floor, with manually deployed ramps for wheelchair users and dedicated wheelchair spaces. Each of the original pilot buses was described as carrying up to 80 passengers, with 33 seats.

Drivers and conductors were reported to receive special training covering passenger safety, passenger care and basic sign language.

For visitors with reduced mobility, older travellers and parents with pushchairs, this is currently the most accessible scheduled public transport in Colombo.

Stops themselves may not all be step-free or have smooth pavements. Check your boarding and alighting stops in advance if you use a wheelchair.

Honestly: for many tourist trips within central Colombo, a tuk-tuk or ride-hailing car will still be quicker and simpler. The Metro Bus was designed mainly for commuters travelling between the suburbs and the city. But several routes are useful.

CM06, the Kollupitiya Circular Route, runs around central Colombo and is the route most likely to suit visitors staying in the city centre. Check the live map for current stops.

CM04, Dematagoda to Panadura, runs south along the coast through Dehiwala and Moratuwa. It may be useful if you are staying in the Mount Lavinia and Dehiwala area.

CM01 and CM03 connect with the Makumbura Multimodal Centre, the terminal for expressway buses to Galle, Matara and the south. If you are heading south by highway bus, a Metro Bus to Makumbura is a comfortable way to reach it from Pettah or Borella.

CM01, CM02 and CM05 pass through Battaramulla and Sethsiripaya, near the parliament area and Diyatha Uyana park.

There is no Metro Bus route to Bandaranaike International Airport. CM05 runs to Ekala and Ja-Ela, which are north of Colombo but still short of the airport at Katunayake. Use the airport express bus, a taxi or a ride-hailing car.

Luggage: these are city buses with standing room and no luggage hold. They are not designed for large suitcases, especially at peak times.

Comfort: Metro buses are air-conditioned, newer, and designed to run to scheduled stops. Many regular buses are not air-conditioned and can be very crowded.

Reliability: Metro buses run to schedules with GPS tracking. Regular private buses often wait to fill up and compete for passengers.

Accessibility: Metro buses are low-floor with ramps. Most regular buses have high steps.

Coverage: Regular buses cover far more of the city and country. The Metro network is seven routes.

Cost: we could not confirm Metro fares. Regular bus fares in Sri Lanka are set by the national transport authorities, with the minimum fare raised to LKR 30 in 2026. Expect Metro fares to be higher than regular non-AC buses, as AC services usually are, but confirm.

In August 2026, the Cabinet approved the purchase of 50 more low-floor buses, and the transport minister said the Metro Bus service would expand to Jaffna and Kandy by the end of 2026, with Galle also named for the next phase.

Lanka Metro Transit's website already refers to corridors in Kandy and Galle. As far as we could find, no Metro Bus routes outside Greater Colombo were operating at the time of writing.

Further depots, including in Ratmalana and Homagama, were planned for the Western Province, and the minister has said the private sector could operate Metro services under contract in future.

The long-term ambition stated in late 2025 was to serve eight major cities within three years.

Download LMT GO before you go and check live arrivals.

Board at the stop, not anywhere along the road; Metro buses stop at designated stops.

Avoid peak hours if you have bags or want a seat.

Give priority seats to older passengers, pregnant women, people with disabilities and clergy. On Sri Lankan buses, front seats are traditionally reserved for Buddhist monks.

Keep valuables secure, as on any crowded transport.

If you have a problem or a lost item, LMT lists phone numbers and a WhatsApp contact on its website.
