Designs for the proposed elevated roadway-viaduct to be built above Uhuru Highway have been completed setting stage for a major upgrade of the busy highway.

Kenya National Highways Authority (KeNHA) Director General Meshack Kidenda said the construction is scheduled to begin next year with completion expected by 2015.

“The road improvement will cover 12km between St. James Hospital and James Gichuru; and will involve construction of an elevated road or flyover,” Mr Kidenda said adding that the project will also involve construction of pedestrian pavements, service roads and a storm water drainage system.

The project, which is being funded by the World Bank at a preliminary cost of US$200 million (Sh17 billion), is part of KeNHA’s plan to improve the thoroughfare from JKIA to Rironi in effort to ease traffic congestion in the city and its environs.

The designs were done by Danish firm COWI Consulting Engineers and Planners.

According to the project team leader Brian Segar of COWI, there will be an overpass over Mombasa Road linking Kapiti/Popo roads junction in South B and South C with a diamond type ramp on the South B side to minimise land acquisition, and a quarter link behind South C from Mombasa Road.

“The proposed design will get rid of roundabouts between Nyayo Stadium and Westlands which cause the most traffic congestion,” he said adding that an overpass will be built from Lang’ata Road to link with Lusaka Road in Industrial Area.

The Nyayo Stadium roundabout will be demolished to pave way for the construction of a single point diamond interchange.

The elevated roadway-viaduct will begin some metres from the Haile Selassie roundabout and will run past the existing University Way roundabout. Haile Selassie Road, Kenyatta Avenue and University Way will all pass below the elevated roadway.
