Construction – Roads

Background

One of the key factors in the quest for improved national productivity is the condition of the road system.  In all countries, it is essential that goods move quickly and cost effectively from seller to buyer.  This is particularly true for development in rural areas, where low labor costs are often offset by higher transport costs. 

Objective

The objective of the economic development mission is to expose government officials and construction industry leaders in the developing country to modern road- building methods and materials used in the U.S.  Participants will be able to see how U.S. road-building companies operate and government regulations affect the industry. 

Potential benefits of this mission

This information allows participants to improve the system of roads and bridges in their country, with the objective of improving the distribution of goods within the country.  It also will open up new export opportunities.  Depending on the specific actions taken, the impact on the developing country can be substantial.
