Narrative:

Pilot flying left seat to get recurrent. Made left turn to hold short crossing runway 15R iah. No runway signs erected. Newly opened runway. Failed to stop prior to crossing. Crossing other aircraft is airborne passed well overhead. Pilot flying familiar with airport and was under impression runway was still closed. Callback conversation with reporter revealed the following information: reporter stated that none of the three crew members on board (one in the jumpseat as an observer) noticed the runway sign which they did see the next day after going back to look over the area of their mistake. The reporter was not familiar with the airport layout and when the other crew members said that they believed the new runway to be closed, and there was construction activity nearby, reporter believed it to be inactive. However, when a general aviation aircraft flew overhead as they crossed the runway, they suspected that it was open and active. Subsequently, the tower controller advised them of their mistake and directed them onto their takeoff runway. After flight, the tower was contacted to discuss this matter further.
