Quick answer
Choosing between the Southern Expressway and the coast road depends on the stretch. The Southern Expressway, opened to Galle in 2011 and later extended to Matara and towards Hambantota, is fast, tolled and inland, cutting Colombo to Galle to roughly one and a half to two hours. The A2 coast road is slow, averaging roughly 30 to 40 kilometres an hour, but passes every beach town and most sights. Use the expressway for long hops and the coast road between nearby stops.

Two roads along the coast
The Southern Expressway is a fast, tolled motorway running inland from the outskirts of Colombo towards Hambantota, with interchanges serving Galle, Weligama, Matara and towns further east. It opened to Galle in 2011, reached Matara a few years later and was extended towards Hambantota around 2020.
The A2 coast road, also called the Galle Road, is the old main road along the coast. It passes through every town and village, alongside the railway for much of the way, with the sea on one side and shops, temples and houses on the other.
The Southern Expressway
The Southern Expressway cuts journey times dramatically. Colombo to Galle takes roughly one and a half to two hours, and Galle to Matara well under an hour. The road is smooth and well maintained, with rest areas and fuel stations.
Tolls are modest, a few US dollars for a car on most journeys, paid at exits. Tuk-tuks and motorbikes are not allowed. The expressway runs inland through paddy, rubber and hills, so there are no sea views and no sights along the way.
- →Speed: much faster than the coast road.
- →Tolls: modest, paid at exits.
- →Scenery: inland countryside, no sea views.
The A2 coast road
The A2 coast road is slow, averaging roughly 30 to 40 kilometres an hour through the towns, with buses, tuk-tuks and pedestrians sharing the road. Traffic is heaviest around Galle, Matara and at school times.
The coast road passes every beach town and most of the south coast's sights, from Ambalangoda's masks to the stilt fishermen of Koggala and the temples near Matara. It is the road for sightseeing, with sea views and endless places to stop.
- →Speed: slow, especially through towns.
- →Sights: passes almost all of them.
- →Scenery: sea views, villages and beaches.
Combining both roads
Most south coast sightseeing days combine both roads. Use the expressway for long hops, such as from the airport or Colombo to Galle, or from Galle to Matara when the stops are further east. Use the coast road between nearby sights, where the expressway would add detours.
A good driver knows when each road saves time. For example, a day from Bentota to Galle might take the coast road for the stops, while a transfer from Galle straight to Tangalle might use the expressway to Matara or beyond and rejoin the coast road for the last stretch.
- →Airport to Galle: expressway.
- →Galle to Mirissa with stops: coast road.
- →Galle to Tangalle direct: expressway, then coast road.
Driving safety
The coast road can be hectic, with buses overtaking at speed, tuk-tuks stopping suddenly and pedestrians crossing anywhere. Most visitors use a driver rather than self-driving. The expressway is calmer, but speed limits are enforced.
Night driving on the coast road is best avoided, as lighting is limited and traffic unpredictable. Plan sightseeing days to arrive at your hotel before dark where possible.
- →Use an experienced driver.
- →Avoid night driving on the coast road.
- →Allow extra time around Galle and Matara.
Planning your routes
Lankan Stays & Trails plans each south coast day around the right mix of roads, so long transfers are quick and sightseeing stretches are slow. Drivers adjust on the day for traffic, weather and how long you want at each stop.
For a first trip, the simplest rule is to use the expressway to reach the coast and the coast road once you are there, saving time on arrival and enjoying the scenery during your stay.
Frequently asked questions
How long does the Southern Expressway take from Colombo to Galle?
Colombo to Galle takes roughly one and a half to two hours by the Southern Expressway, depending on traffic getting out of Colombo. From the airport, allow around two to two and a half hours. The coast road takes three hours or more.
How much are the tolls on the Southern Expressway?
Tolls are modest, a few US dollars for a car on most journeys, paid at the exit. Prices depend on the distance and vehicle type. Drivers usually include tolls in their daily rate, so confirm when booking.
Does the Southern Expressway go to Tangalle?
The expressway extends beyond Matara towards Hambantota, with interchanges serving the Tangalle area. Drivers often leave it near Beliatta and take local roads to Tangalle, which is quicker than the coast road from Matara.
Can tuk-tuks use the Southern Expressway?
No. Tuk-tuks, motorbikes and bicycles are not allowed on the Southern Expressway. They must use the A2 coast road or other local roads, which is one reason long trips by tuk-tuk take so much longer.
Is the coast road worth the extra time?
Yes, for sightseeing. The A2 coast road passes beaches, fishing villages, temples and most of the south coast's sights, with sea views much of the way. For transfers without stops, the expressway saves a lot of time.
Is it safe to drive yourself on the south coast?
It is possible, but most visitors use a driver. The coast road is busy and unpredictable, with buses, tuk-tuks and pedestrians. A valid international driving permit and local endorsement are needed. The expressway is calmer for those who do drive.
Which road should I use from the airport to the south coast?
Use the expressway. From Bandaranaike International Airport, a link road and the Colombo outer ring connect to the Southern Expressway, avoiding the city centre. It reaches Galle in roughly two to two and a half hours, against far longer by the coast road.
