In 2002, a study assessed the structural condition of New Jersey's Interstate network and determined its rehabilitation needs for the next 30 years. Deflection testing was performed on approximately 750 testing miles, and cores and bores were also taken. In addition, a ground penetration radar survey and a limited visual inspection were carried out on the entire length of the Interstate network, including the associated ramps.
