The Interamericana is being transformed south of Liberia. A stretch between Liberia and Cañas is nearly finished.
The job widens the key highway from two to four lanes. The road work alone is $85.6 million, and $44.6 million more is being spent on additional projects, said the Ministerio de Obras Públicas y Transportes.
With four lanes, officials had to widen or build 18 bridges at a cost of $27.7 million. The contract covers 50.6 kilometers or about 31.3 miles. The government made the decision to put down 10 inches of concrete instead of asphalt because the concrete will last longer.
Eventually the wider highway will run all the way north to the Nicaraguan border. Much of the money is coming from a loan by the Banco Interamericano de Desarrollo.
The time of year around the July 25 Anexión holiday, officials usually announce major projects for Guanacaste and the Nicoya peninsula. These are not those types of projects. These jobs have been in the works for years and the contract was let in 2011.
