The rig was headed west, towing a Jeep, when the driver apparently lost his power steering.
After hitting two cars, the Ford careened across the bridge, knocking a 13-foot section of the south railing to the riverbank below.
The pickup then landed against metal scaffolding that holds a billboard alongside the bridge.
The driver for Lennies East Coast Auto Transport of Long Island climbed out and onto the scaffolding.
A heavy wrecker pulled out the pickup.
Three occupants of the two struck cars were taken to Hackensack University Medical Center with injuries that police said weren’t life-threatening.
Traffic was stopped in both directions for 3½ hours.
