Garlic Collective - Sri Lanka Built Different Series

Colombo's public transport network is changing.

From September 29, 2026, Lanka Metro Transit (LMT) expanded its Metro Bus service with five additional routes, building on the two routes that were already operating. The expanded network now covers seven Metro Bus corridors connecting areas including Makumbura, Kadawatha, Athurugiriya, Battaramulla, Panadura, Ekala, Kahathuduwa, Colombo Fort and Pettah.

For commuters, the important question is not simply “What are the new Metro Bus routes?”

It is:

Which route should I take, where can I get on, where can I change buses, and how can I know when my bus is actually coming?

That is where the combination of the physical Metro Bus network and the LMT-GO digital platform becomes particularly useful.

This guide explains the new Colombo Metro Bus routes, their stops, key connections, and how commuters can use LMT-GO to make everyday journeys easier to understand.

Colombo Metro Bus Network 2026 at a Glance

The expanded Metro Bus network currently consists of seven routes:

*Distances are based on the route information supplied by Lanka Metro Transit. The CM08 distance requires clarification because different LMT materials have shown different figures. This article therefore does not treat one figure as definitive.

The seven routes provide connections across major residential, commercial, employment and transport areas in Colombo and the surrounding Western Province.

CM01 – Makumbura to Pettah

CM01 connects the Makumbura area with Colombo’s central commercial district and Pettah.

CM01 Stops

1. Makumbura
2. Kottawa
3. Pannipitiya

14. Castle Hospital
15. Singer Mega – Colombo 8
16. Wijerama Halt
17. Hedges Court
18. Maradana
19. Colombo Fort
20. Pettah

Who may find CM01 useful?

CM01 can be particularly relevant for commuters travelling from the Makumbura, Kottawa, Pannipitiya, Battaramulla and Rajagiriya areas towards Colombo Fort and Pettah.

It also creates useful connections with other Metro Bus routes around Battaramulla, Rajagiriya and Colombo Fort.

CM02 – Millennium City to Colombo Fort

CM02 provides a connection from the Athurugiriya area towards Colombo Fort.

CM02 Stops

1. Millennium City
2. Athurugiriya Hospital
3. Athurugiriya Town
4. Nisaco Mall

20. Colombo Fort
21. Pettah

Who may find CM02 useful?

This route creates a direct Metro Bus corridor for commuters from Millennium City and Athurugiriya through Malabe, Thalangama, Battaramulla-area connections and central Colombo.

For someone travelling from the Athurugiriya side towards Colombo, the route provides another public transport option without requiring a private vehicle for the entire journey.

CM03 – Kadawatha to Makumbura

CM03 connects the northern side of the Colombo metropolitan area with Makumbura through several important urban locations.

CM03 Stops

1. Makumbura
2. Kottawa
3. Pannipitiya 02
4. Maharagama

12. Campbell Park
13. Dematagoda
14. Orugodawatta
15. Kelaniya University
16. Kiribathgoda
17. Mahara Junction
18. Kadawatha

Why CM03 is important

CM03 crosses several major residential and employment areas between Makumbura and Kadawatha.

It also intersects with other Metro Bus corridors around:

1. Makumbura
2. Borella
3. Dematagoda

This makes it particularly interesting for commuters who may need to combine Metro Bus routes rather than travel on a single route from beginning to end.

CM04 – Dematagoda to Panadura

CM04 provides a north-to-south connection from Dematagoda towards Panadura.

CM04 Stops

1. Dematagoda Railway Station
2. Borella 02 – YMBA
3. Independence Arcade
4. Thummulla Junction
5. Bambalapitiya
6. Wellawaththa

13. Katubedda Junction
14. Moratuwa
15. Egodauyana
16. Mahanama Junction
17. Panadura Base Hospital
18. Panadura

Who may find CM04 useful?

CM04 links several major locations along Colombo’s southern corridor.

For passengers travelling between Dematagoda, central Colombo, Bambalapitiya, Wellawatta, Dehiwala, Mount Lavinia, Moratuwa and Panadura, the route creates a continuous Metro Bus corridor.

It also connects with other routes around Dematagoda, Borella and Bambalapitiya.

CM05 – Battaramulla to Ekala

CM05 creates a long east-to-north corridor between Battaramulla and Ekala.

CM05 Stops

1. Battaramulla Junction
2. Sethsiripaya
3. Diyatha
4. NAITA
5. Rajagiriya
6. Castle Hospital
7. Borella 02 – YMBA
8. Campbell Park
9. Dematagoda
10. Peliyagoda – New Kelani Bridge
11. Peliyagoda 02
12. Hekitta Junction
13. Wattala
14. Hendala
15. Mabola
16. Mahabage
17. Kandana
18. Weligampitiya
19. Ja Ela
20. CTB Junction
21. Ekala

Why CM05 stands out

One of the useful characteristics of CM05 is the number of connections it creates with other Metro Bus corridors.

Passengers travelling through Battaramulla, Rajagiriya, Borella and Dematagoda can potentially connect with other routes instead of depending on a single direct service.

The route also extends the Metro Bus network towards Wattala, Kandana, Ja-Ela and Ekala.

CM06 – Kollupitiya Circular Route

CM06 is different from the other routes because it operates as a circular corridor around important areas of Colombo.

CM06 Stops

1. Kollupitiya
2. Liberty Bus Stop
3. Public Library
4. Town Hall
5. Nelum Pokuna
6. Independence Square
7. Jawatta Road
8. Jawatta
9. Hirdaramani
10. VTA / AAT
11. Narahenpita
12. Anderson Flat
13. Havelock
14. W.A. Silva Mawatha
15. Wellawatta
16. Bambalapitiya

Why a circular route matters

Not every journey in Colombo starts in a suburb and ends in Fort.

Many daily trips happen within Colombo itself.

A circular route can therefore be useful for people travelling between areas such as Kollupitiya, Town Hall, Nelum Pokuna, Independence Square, Narahenpita, Havelock, Wellawatta and Bambalapitiya.

It also provides potential connections with longer Metro Bus corridors.

CM08 – Kahathuduwa to Fort

CM08 connects Kahathuduwa and surrounding southern areas with Colombo Fort and Pettah.

CM08 Stops

1. Kahathuduwa
2. Kesbewa
3. Piliyandala Bus Stand Stop
4. Lanka Fiber Fabrica
5. Weerasinghe Mawatha
6. Werahera
7. Boralesgamuwa
8. Raththanapitiya
9. Pepiliyana
10. Kohuwala
11. Kirulapone
12. Havelock
13. Thimbirigasyaya
14. Thummulla
15. Kollupitiya
16. OGF – Galle Face
17. Fort
18. Pettah

Important note about the CM08 distance

The route information currently available from LMT contains a discrepancy regarding the total distance of CM08. One route summary gives 35.7 km, while another route card gives 29.9 km.

For that reason, it is better to use the official stop sequence above rather than presenting one distance as definitively verified.

The Most Important Part: Understanding the Connections

A bus route becomes much more useful when you understand how it connects with other routes.

The seven Metro Bus routes should not necessarily be viewed as seven completely separate services.

Several locations act as connection points between corridors.

Makumbura

CM01 and CM03 both serve Makumbura.

This makes Makumbura an important connection point for passengers travelling between the southern side of Colombo and the Kadawatha corridor.

Battaramulla and Sethsiripaya

CM01, CM02 and CM05 all pass through the Battaramulla/Sethsiripaya area.

This creates a useful cluster of Metro Bus services for people travelling through Sri Jayawardenepura Kotte and surrounding areas.

Rajagiriya

Rajagiriya is served by CM01, CM02 and CM05.

For commuters, this means Rajagiriya can function as an important interchange area when planning journeys between different parts of the network.

Borella

CM03, CM04 and CM05 all serve the Borella area.

This makes Borella another important connection point.

Dematagoda

CM03, CM04 and CM05 pass through Dematagoda.

Passengers may therefore be able to use Dematagoda as a transfer point depending on their origin and destination.

Colombo Fort and Pettah

Several routes connect with Colombo Fort and Pettah, including CM01, CM02 and CM08.

These locations remain particularly important because they are major transport and commercial areas within central Colombo.

Kollupitiya and Bambalapitiya

CM06 provides a circular connection through Colombo while CM08 passes through Kollupitiya.

CM04 and CM06 also provide connectivity around Bambalapitiya and Wellawatta.

This means the network can be viewed as a combination of longer suburban corridors and shorter urban connections.

How to Plan a Colombo Metro Bus Journey

You do not always need a bus that starts exactly where you are and ends exactly where you want to go.

Instead, think about your journey in three steps:

1. Find your nearest Metro Bus stop.

Look at the routes passing through your area.

2. Check where those routes go.

If your destination is not directly served, identify a useful interchange such as Rajagiriya, Borella, Dematagoda, Makumbura, Kollupitiya or Colombo Fort.

3. Plan the connection.

You may need to get off one route and continue using another.

This is where a digital journey-planning tool can make the network considerably easier to understand.

LMT-GO: Putting Your Metro Bus Journey on Your Phone

One of the most important parts of the new Metro Bus experience is not only the buses themselves, but the digital layer supporting them.

Lanka Metro Transit provides the LMT-GO mobile application for Metro Bus passengers.

LMT describes LMT-GO as its official app, with functions including live GPS bus information, stop arrival alerts, journey information and digital ticketing features.

As the Metro Bus network expands, an app like LMT-GO can help commuters move from simply knowing a route exists to understanding how to actually use it.

What Can You Use LMT-GO For?

1. Check buses on a live map

LMT-GO provides real-time bus tracking through an interactive map.

This can help you understand where buses are instead of relying only on a printed timetable or waiting without knowing when the next bus will arrive.

LMT's own website also highlights live GPS bus radar and real-time stop alerts as part of the LMT-GO platform.

2.Find Nearby Bus Stops

The application can use your phone's location to show your position and nearby bus stops.

This is particularly useful when you are unfamiliar with an area or are walking towards a Metro Bus stop. LMT's privacy policy specifically states that location data is used for displaying your position, nearby stops and calculating travel routes.

3. Plan a journey

Instead of starting with a route number, you can think about your journey from where you are → where you want to go.

The LMT-GO listing describes journey-planning functionality that can provide route options, stops, transfers, walking directions, journey time and fare information.

This is particularly useful as the network becomes larger.

For example:

Athurugiriya → Colombo Fort

Rather than trying to memorise CM02, you can use your starting point and destination to understand the available route and stops.

4. Understand transfers

Suppose your destination is not directly served by your starting route.

A journey planner can help you identify where a transfer may be required.

For example, someone travelling through the Rajagiriya area could potentially have several Metro Bus corridors available depending on their destination.

Instead of memorising all seven routes, commuters can use the network as a connected system.

5. Check route and timetable information

LMT-GO provides route and timetable information for Metro Bus services.

This becomes increasingly useful as more routes and stops are added.

Recent reporting on the September 2026 expansion also confirms that passengers can access timetables, designated bus stops and travel information through LMT-GO.

6. Digital ticketing and QR payment

The current LMT-GO listing also describes QR-based bus ticketing and payment, along with transaction history and offline access to valid tickets.

That means the app is intended to become more than a route map.

It is being developed as a digital passenger platform around the Metro Bus network.

7. Alerts and accessibility features

The LMT-GO listing describes alerts for approaching buses and service disruptions, as well as accessibility-related functions such as wheelchair-bay booking and accessibility availability.

The availability of individual features can depend on the route and current service rollout, so passengers should check the app for the latest information rather than assume every feature is available on every route.

A Practical Example: Athurugiriya to Colombo Fort

Imagine you live around Athurugiriya and need to travel to Colombo Fort.

Instead of starting with a Google search for every possible bus, you could approach the journey like this:

1. Starting area: Athurugiriya
2. Nearest relevant Metro Bus corridor: CM02
3. Destination: Colombo Fort
4. Route: CM02

Useful stops along the way: Athurugiriya Town → Malabe → Thalangama → Sethsiripaya → Rajagiriya → central Colombo → Colombo Fort

Before travelling, LMT-GO can be used to check available route information and, where supported, live bus location and arrival information.

The journey becomes a simple digital workflow:

Find → Check → Travel

Another Example: Makumbura to Pettah

For a passenger travelling from Makumbura towards Pettah:

Starting point: Makumbura

Route: CM01

Key locations: Kottawa → Pannipitiya → Battaramulla → Rajagiriya → Maradana → Colombo Fort → Pettah

LMT-GO can then be used to check the current service information before leaving.

This is especially useful because real-world bus operations can change due to traffic, service conditions and other factors.

LMT-GO Makes the Network Easier to Understand

The bigger a public transport network becomes, the harder it can be for a first-time passenger to understand.

Seven routes are manageable when presented on a map.

But for a commuter, there are still questions:

1. Where is my nearest stop?
2. Which route should I take?
3. Where should I get off?
4. Can I change to another route?
5. When is the next bus?
6. How long might the journey take?
7. What fare information is available?
8. Is there a service disruption?

A digital platform can bring many of those questions into one place.

That is why the LMT-GO app is an important part of the Metro Bus story.

The physical infrastructure is the bus network.

The digital infrastructure is the information layer that helps people navigate it.

From Roads to Digital Journeys

Public transport is no longer only about vehicles and roads.

Modern public transport increasingly depends on information.

A passenger needs to know:

Where is the vehicle?

When will it arrive?

Where should I get off?

What route should I take?

Can I connect to another service?

The LMT-GO platform represents an attempt to make some of that information accessible through a smartphone. LMT itself describes the service around live GPS tracking, arrival alerts and digital timetable access.

For Colombo commuters, that digital layer could become increasingly important as the network expands.

Why the New Metro Bus Network Matters for Colombo

The expansion is significant because it changes the geographical reach of the Metro Bus concept.

The network now connects a wider collection of areas across Colombo and its suburbs, including:

1. Makumbura
2. Kottawa
3. Maharagama
4. Nugegoda
5. Kadawatha
6. Kiribathgoda
7. Athurugiriya
8. Malabe
9. Battaramulla
10. Rajagiriya
11. Borella
12. Dematagoda
13. Wattala
14. Kandana
15. Ja-Ela
16. Wellawatta
17. Dehiwala
18. Mount Lavinia
19. Moratuwa
20. Panadura
21. Kahathuduwa
22. Piliyandala
23. Boralesgamuwa
24. Kollupitiya
25. Colombo Fort
26. Pettah

The September 2026 expansion added five routes to the two already operating, bringing the total to seven corridors.

The Ministry of Transport had previously announced plans for a larger Metro Bus rollout and supporting infrastructure as part of the development of Lanka Metro Transit.

What Does This Mean for Colombo Commuters?

The biggest change may not be one individual route.

It is the possibility of thinking about Colombo travel as a network.

Instead of:

“Which bus goes directly from my home to my destination?”

The question can become:

“Which Metro Bus route gets me closest, and where can I connect?”

That is a different way of using public transport.

For example, a passenger may travel:

Suburb → Metro Bus → interchange → Metro Bus → Colombo

rather than depending on one direct vehicle.

The usefulness of that model will depend on actual service frequency, reliability, interchange convenience, traffic conditions and passenger experience over time.

But the network now provides more corridors to work with.

Seven Routes, One Network

Here is the simplest way to remember the expanded Metro Bus network:

CM01

Makumbura → Pettah

CM02

Millennium City → Colombo Fort

CM03

Kadawatha → Makumbura

CM04

Dematagoda → Panadura

CM05

Battaramulla → Ekala

CM06

Kollupitiya Circular

CM08

Kahathuduwa → Fort

The route numbers may look complicated at first.

But once the major interchange points are understood, the network becomes easier to visualise.

Think of:

Makumbura + Battaramulla + Rajagiriya + Borella + Dematagoda + Kollupitiya + Colombo Fort/Pettah

as some of the important points where different parts of the network come together.

A Practical Tip: Don't Rely on One Source Alone

Transport information can change.

Routes can be adjusted.

Stops can be added.

Timetables can change.

Traffic can affect actual arrival times.

Therefore, before travelling, it is useful to check the latest LMT information and LMT-GO rather than relying on an old social media post, screenshot or route list.

This is particularly important during the early stages of a network expansion.

The LMT-GO app is designed to provide live and journey-related information, while LMT's official channels provide updates about the service.

Sri Lanka Built Different Blog Series: What Can We Learn From Colombo's Metro Bus Expansion?

Sri Lanka's transport challenges are not new.

Traffic congestion, long commuting times and the complexity of travelling across the Colombo metropolitan area affect thousands of people every day.

But the way we solve those problems can evolve.

The Metro Bus expansion is interesting not simply because more buses have been introduced.

It is interesting because the physical transport network is being combined with a digital information layer.

Routes.

Stops.

GPS tracking.

Journey planning.

Digital tickets.

Passenger information.

These pieces work together to create something more useful than a list of buses.

They create a connected mobility system.

For a country increasingly moving towards digital public services, this is an important direction to watch.

And for Colombo commuters, the immediate opportunity is simple:

Know your route. Know your connections. Check the information before you travel.

The next time you need to cross Colombo, don't just ask:

“Which bus goes there?”

Ask:

“How does the network get me there?”

That is where Colombo's new Metro Bus system becomes much more interesting.
