The Tacna-La Paz interconnection is one of the most important structures of this kind between Bolivia and Peru, since it allows for direct exit from the capital of Bolivia to the city of Tacna. The connection is part of the commitments made during the presidential and bilateral meetings held to consolidate integration and to give a strong impetus to the development of this work.
In 2010, the presidents of Peru and Bolivia convened to proceed with the asphalting of more than 300 km of the Tacna (Peru) - La Paz (Bolivia) highway. The objective was strengthening Peruvian-Bolivian integration, and transforming this road into an important route for bilateral trade and for the transit of people and vehicles to the Pacific Ocean (Ilo Declaration, 2010).
In 2015, within the framework of a new presidential meeting and an infrastructure ministerial meeting, the commitment was renewed on the rationale that this road corridor may contribute to economic and social development of the populations settled on the border area. To this end, a binational plan was developed, with complementary actions for road paving. Such measures include specific working groups and activities linked to the environment and transboundary water resources; security and defense; economic development, social policies and institutional strengthening; and infrastructure for integration and development (Isla Esteves Declaration, 2015).
The highway crosses the department of Tacna in Peru and the department of La Paz in Bolivia. This territory covers an area of 150 thousand km2 and shelter about three and a half million people. In 2014, the GDP of both departments was estimated over USD 10 billion. (COSIPLAN, 2016).
This integration roadway consists of two road projects from COSIPLAN’s portfolio, from the 5-Project Group for the Central Inter-Oceanic Corridor. In Peru, the road connects the city of Tacna with Collpa, on the border with Bolivia, and in that country, it connects Hito IV with the La Paz city. Both projects have been divided into sections for the implementation of the required works for paving.
In Peru, the Tacna - Collpa road has 4 sections, the first of which, up to kilometer 43.6, is paved at the level of asphalt layer. The second section is 50.4 km long, and represents an investment of USD 79 million. The works there started in August 2016 and will finish in February 2018. The third section is 52.2 km, with an investment of USD 43 million, and its development period is from September 2016 to April 2018. The last section, up to the border with Bolivia, is 41.2 km long, and has an investment of USD 45 million. The works began in February 2016 and are expected to be completed in October 2017.
In Bolivia, La Paz - Hito IV highway is also divided into four sections and the first one is paved until the Capiri Railroad intersection. The second section, between Capiri and Central Chama is 25.25 km, and is in progress, with an investment of USD 16 million financed by CAF. The works are estimated to be completed by 2017. The next stage involves paving 27.44 km between Central Chama and Nazacara. This work is also in progress, with an investment of USD 21 million, and it is expected to be completed in 2017.
The fourth section, linking Nazacara with Hito IV, was divided into three sub-sections, the first two being the contracted works. The first sub-section joins the 25 km between Nazacara and San Andrés de Machaca, with a USD 32 million investment financed by FONPLATA. The second sub-section, a road between San Andrés de Machaca and Santiago de Machaca, is 32.7 km, and the investment amounts to USD 37 million, financed by the IDB. Finally, the sub-section from Santiago de Machaca to Hito IV, of about 50 km, is under tendering process and has an estimated USD 66 million investment.
In addition, this connection to the Peruvian coast is complemented by two other projects from COSIPLAN’s portfolio. The first one is the construction and improvement of the Camana - Matarani - Ilo road, which is in progress, with an estimated investment of USD 438 million. This work is expected to facilitate the connection between Ilo Port and Matarani. Its inauguration is estimated for April 2017. The second project aims at expansion, improvement, and modernization of the Ilo port, with the purpose of transforming it into a modern multi-purpose terminal. In this sense, a private initiative to carry out the design, construction, operation, maintenance, and operation of this terminal is currently under assessment. The estimated investment amounts to USD 230 million.
