The Inchope road junction allows the junction de-levelling between two major roads in Mozambique, namely the N1 (North/south route) and N6 (connecting Beira city to Machipanda border with Zimbabwe).

Before the Improvement Works, erosion and sliding problems existed throughout the embankments and slopes along the interchange, interfering with the stability of the road platform at the top. In addition, the drainage system revealed to be insufficient and showed several operating problems.

Under this context, REVIMO – as the concessionaire of N6 road – requested BETAR to assess the interchange's condition and to define Works for general Rehabilitation. BETAR designed a new layout which included a comprehensive improvement of the drainage system, with several additions such as dissipation basins, drainage chutes, flow energy dissipators, concrete ditches, etc. Also, the new design included the rehabilitation and strengthening of the embankment and slopes through different interventions, ranging from shotcrete and soil nailing, “geocells” grids and mortar rubble revetment to slope grade adjustments and general reprofiling.

A team from BETAR also performed on-site supervision during works, including Quality Control, Quantities validation and Planning.
