The execution of the project would be managed by Mideast Technology Initiative "Tecnológica Centro Oriental" (INTECO),[2] a non-profit organization that groups municipal governments, academic and industrial institutions of the region.

The new line would include two stops in Caguas that connect to the Tren Urbano (Urban Train in English) in San Juan.

[5] San Juan is the capital of Puerto Rico, and its metropolitan area has a population of approximately 2 million, almost one half of the main island's total.

[6] Caguas, located about 20 miles (32 km) south of San Juan, is the fifth-largest city in terms of population with approximately 200,000.

As of August 2009 (2009-08), no work to date has begun and the project remains postponed, although one additional reversible (zipper-lane) express lane along PR-52 has since been added.

The original schedule was set to begin with Tren Interurbano's technical proposals being revealed by the end of 2007 with several firms bidding for the construction contract shortly thereafter.
