Another agency, known as the New Jersey Highway Authority, was established in 1952 and responsible for maintaining the Garden State Parkway, which opened to traffic in 1954. In July 2003, the New Jersey Legislature approved and Governor James McGreevey signed into law a bill consolidating the New Jersey Turnpike Authority and the New Jersey Highway Authority. The main headquarters of the Turnpike Authority before consolidation was in East Brunswick, while the main headquarters of the Highway Authority was in Woodbridge Township. A few years later, the headquarters of the consolidated Turnpike Authority was relocated to an eight-story office tower on Main Street in Woodbridge, nearby exit 11 on the NJ Turnpike.
