Romero will lead a 20 strong department which oversees communications for ten institutional divisions covering roads, airports, rail, post and maritime ports facilities. He will manage Daniel Salado, who heads media relations.
Romero replaces Inmaculada Mardones, who has returned to her previous job as a reporter for El Pais. He will report to public works minister Magdalena Alvarez.
The ministry is gearing up for a slew of projects under the socialist government's new strategic plan for infrastructures and transport. Plans include ambitious work to expand the country's road, rail and airport facilities.
According to a ministry spokesman, focus will be on communicating the government's public projects, particularly those based around Madrid's 2012 olympic bid and the inauguration of the city's new international airport terminal next year.
Romero is also likely to have to deal with growing criticism of state rail company Renfe, which has seen increasing delays in its plans to build a fast link between Madrid and Barcelona.
Romero was formerly media relations director at the Navarre consumer defence bureau, prior to which he was chief executive at MBO Comunicacion.
