Moving ahead quickly on infrastructure projects is a key component of the economic stimulus and recovery plan the governor announced last month.
Other state agencies also have been told to expedite projects already planned.
The state will invest $2.8 billion in transportation infrastructure projects through the end of 2009. They include construction work on the Garden State Parkway, New Jersey Turnpike and Atlantic City Expressway.
Another $1.2 billion in transportation projects has been identified, and the governor said they will move forward if federal economic stimulus aid becomes available.
