Accessibility is a distinct advantage at the International Plaza Center in Tinicum Township - the first recorded European settlement in the state. Not only is it adjacent to the Philadelphia International Airport, but it's also convenient for Center City Philadelphia, New Jersey and Delaware, with excellent highway access to I-95. The center has an excellent view of the airport runway but behind soundproof glass providing a quiet atmosphere. Externally, the center has a distinctive white columned portico. Businesses nearby include many to do with the airport - the largest in the Delaware Valley region and the global hub for US Airways - but also the American Competitiveness Institute, a national electronics center of excellence. The John Heinz Wildlife Refuge is close by. Of the 82 business establishments in the zip code, 20 are in finance and insurance, with transportation and warehousing not far behind.
