The Sh28 billion Dongo Kundu bypass meant to provide an alternative route to South Coast will be ready in about four years, the Kenya National Highways Authority (KeNHA) has said.
It will save locals and visitors the pain of using the congested and unreliable Likoni ferry crossing, known for a breakdown of vessels.
The breakdowns have been blamed on the fact that some of the ferries are old.
Phases two and three started yesterday. KeNHA Deputy Director for special projects Kungu Ndungâ€™u said the section of the road between Kibundani and Mwangala will be completed in the next two years.
The project includes what will become Kenyaâ€™s longest bridge, across the Mteza and Mwache creeks, that will cost Sh24 billion.
The rest of the money will fund a seven-kilometre dual carriageway from Kibundani, on the southern end, to the seaside at Mwangala.
The two phases are part of the 17.5km Dongo Kungu bypass road from Miritini in Mombasa County to Ngâ€™ombeni in Kwale County.
Phase two of the route comprises nine kilometres of road near the sea.
Meanwhile, Ndungâ€™u said the government has released Sh450 million, out of the Sh517 million needed, to compensate 600 landowners. â€śWe expect to compensate all landowners by the next financial year.
He said KeNHA will plant mangroves on 45 acres after clearing 15 acres to pave way for construction of bridges.
