River Sabaki Bridge: Mouth of a Lifeline

9 km north of Malindi via B8 Malindi-Mombasa Road you cross the Sabaki River Bridge, appreciably close to the point where Athi-Galana-Sabaki River, Kenya’s second longest, debouching its waters into the Indian Ocean after flowing for 390 km from its headwaters on the eastern flank of Aberdare Mountain Range. It first flows as the Athi in Machackos County, then as the Galana as it crosses Tsavo East National Park, diving the park in half, and finally as Sabaki as it nears its terminus.

River Sabaki estuary, about 2 km downstream, part of which is observable from Sabaki Bridge, covers an area of about 6 km2 of sandbanks, mudbanks, dunes, freshwater pools and marshes. The state and size of the estuary varies seasonally depending on river flows, ergo Sabaki River mouth is one of the Important Bird Areas in Kenya, hosting a prolific display of the migratory Madagascar Pranticole and is also an important nesting, roosting and feeding ground for gulls and terns.

A total of 68 species have been recorded here with a maximum count of 11,753 birds. Peak numbers are often in April. Counts of tern and gull roosts have also been carried out at peak times when birds were most abundant. High numbers of terns have been recorded in February with a night-time roost of Sundowners in the region of 80,000 birds – day time counts occasionally reach 25,000 birds. Other species recorded in sufficient numbers at River Sabaki estuary include; pelicans, cormorants, herons, flamingos, ducks, geese, waders, gulls, and terns.

Away from birding, the inland impact means the outflow of Sabaki River, which transports a large amount of suspended load from the inland, especially during the rainy and wet seasons, to the northern part of the Malindi area, also blocks off penetration of sunlight into the water and around Sabaki. As a result, the marine impacts are definitely represented by the formation of coral reefs, in diminution, because, naturally, corals invariably prefer clean, warm and nutrious sea waters.

To further compound the effect, the drier and warmer climate in the region north of Malindi, fused with a large volume of sands imported by Athi-Galana-Sabaki River also appears to give a better condition for the formation of extensive coastal dunes, most bulbous at Mambrui. Route B8 is a crucial road linking Mombassa to Tana River and Lamu Counties, which has not always been a smooth transitory.

The keen traveller enroute Mambrui will easily notice that River Sabaki Bridge is of a modern development. Not too long ago, the old Sabaki Bridge was a one-lane steel suspension bridge, built in 1962 as part of the B8 Road, the only trunk road to link the so dubbed North Coast to North-Eastern (Tana River and Garissa counties) and Lamu, but it was not maintained properly and suffered irreversible damage, rendering it unsafe and fraught with danger. In 1997, the new 224 ms bridge was reconstructed to provide year-round vehicular access across the Sabaki River.


Kenya is blessed with several rivers, each playing a vital role in the country’s ecosystem, economy, and culture. The longest of these is the Tana, stretching approximately 1,000 kilometers from its source in the Aberdare Mountains to the Indian Ocean. Long, wide, short, seasonal, the rivers that crisscross Kenya each contributes to the natural beauty, biodiversity, and socio-economic success.
