The Dongo Kundu bypass, which is part of a three-phase plan to decongest Mombasa is set for completion in 2018.
The aim for finishing the project in two years is to raise the standard of the Mombasa free trade zone to that of the zone in Dubai.
It will provide alternative routes to the South Coast and connect it to the mainland via a bridge and bypass across Muache Creek, west of Mombasa Island.
“The bypass will consist of four bridges through swampy land and ocean," the state said on Monday when President Uhuru Kenyatta crossed the Likoni ferry channel.
Uhuru also visited the Kenya Ferry Services headquarters accompanied by Tourism Cabinet Secretary Najib Balala and KFS officials.
“The bypass will run two kms west of Moi International Airport in Mombasa and connect the Likoni-Diani and the Mombasa-Nairobi highways.”
The Dongo Kundu project measures about 17.5 km from Miritini at the mainland to Ng’ombeni to the south mainland.
Phase one of the construction will be of a 10-km stretch from Miritini to Kipevu, linking the port to the Mombasa-Nairobi highway.
The second phase will be from Mache to Dongo Kundu, a stretch that will have long-span bridges.
The third phase will begin at Dongo Kundu to Kibundani and join Likoni-Lunga Lunga road.
