Citigroup and Abertis, which is based in Barcelona, Spain, have agreed to invest $5.5 billion in repairing and upgrading the Pennsylvania Turnpike and will have to meet certain management standards imposed by the state. Officials said the companies would have to abide by limited toll increases already proposed by the state. The state has proposed a 25% hike in the highway's tolls in 2009 followed by 2.5%, or inflation-linked, increases in following years. A daily average of 447,441 cars used the highway during 2005, according to state figures. Rendell, a Democrat, said Pennsylvania would use the billions of dollars raised from leasing the highway to repair and upgrade roads and bridges across the state. Abertis operates interests in Atlanta International Airport and Burbank Airport in the United States. Copyright 2008 Agence France-Presse
