To provide a transportation link between Brazil and Guyana to facilitate trade and cultural exchanges between the two countries. The improvement to this road will interconnect and facilitate trade with the state of Roraima in Brazil and will also provide a complete integration of the countries in the Guyana Shield Hub as it intersects with the proposed East West transportation network linking Venezuela with Guyana, Surinam and French Guyana.

Pavimentação do trecho Bonfim - Normandia e construção das pontes sobre o Rio Arraia (BR-79) e Itacutu (BR-80), esta última na fronteira com a Guyana, To pave the existing road between Lethem (Guyana), located at the border of the Brazilian state of Roraima, to Linden. For the interconnection Boa Vista-Georgetown, the route is comprised of the following sections: Georgetown to Linden - This road is already paved to accommodate traffic at international standards; Linden to Lethem - 450 Km of gravel surfaced road which will require upgrading and will require the replacement of some 80 drainage structures. Two major river crossings are included in the project, including the bridge across the Demerara River at Linden, which is in reasonable condition, but only capable of accommodating one-lane traffic and will require extension, and the Kurupukari river mid-way on the route from Linden to Lethem; Lethem - Bonfim - Boa Vista: this section has already been completed by the Government of Brazil, except for the Bridge across the Takutu River on the border with Brazil, which is being addressed as a separate project by IIRSA.

The Pre-Feasibility Study was completed in January, 2009 by the consultants Mott MacDonald Ltd. of the UK in association with CEMCO Inc. of Guyana.

The Feasibility Study is in progress with a duration of 48 weeks and concludes on Feb. 2011 .  The scope of works also includes identification of possible sources of financing.  Two addendums have expanded the scope of works previously covered under the enviromential/social and  economic aspects.

The Government of Guyana's National Development Strategy has been formulated after intensive collaboration between the public and private sector and has identified the Linden-Lethem road as the most essential north-south link in the transportation network of Guyana and is in accordance with the overall objectives of the strategic vision of IIRSA. As a result of bi-lateral agreements between the Governments of Guyana and Brazil on the necessity of improving the road link, a feasibility study was undertaken in 1989 under the funding from the European Union and an Environmental impact assessment was commissioned by the Government of Guyana in 1994. A second feasibility study was also performed in the year 2000. These studies recommended upgrading to all weather gravel road with new drainage structures. Now the Government of Guyana considers important to have the first phase completed, which consists of the updated feasibility and environmental studies, and the completion of the engineering designs, which are being financing by the IDB (firing funds).
