The board of directors for Dallas/Fort Worth International Airport have approved an eight-year project that will renovate the facility's four original terminals. The first major expenditure is a $20.75 million package for the URS Corp. of Dallas to begin design work for terminals A, B, C and E, which opened with the airport in 1974. Airport officials estimate the overall cost will be between $1.5 billion and $2 billion; funding will come from bond sales, available capital and other sources. Construction will begin in early 2011, just after Super Bowl XLV in Arlington, Texas. Work on Terminal A should be completed sometime in 2014, and the entire project is slated to finish up by the end of 2017.
