EDISON - New Jersey drivers are likely to face rough riding when they hit the road, according to a new report.

The Transportation Department report finds half of the state's highways are deficient. That means they're chock full of potholes and cracks that slow traffic and lead to vehicle repairs.

The percentage of deficient roads has hovered near the 50 percent mark since 2004.

Twenty percent are rated in "good" condition and 30 percent are "fair."

DOT Commissioner James Simpson says Gov. Chris Christie's transportation plan calls for spending $284 million on road repairs in the first year alone.

Christie has proposed a five-year, $8 billion transportation capital plan that would begin in fiscal year 2012.

NJDOT maintains slightly more than 13,000 lane miles of roads, shoulders and ramps statewide. The road condition report rates 8,400 lane miles of roads.
