Construction on the Delaware Memorial Bridge was supposed to wrap by 6 a.m., however, it ran long.
Only one lane of the Turnpike was getting by during most of the morning rush resulting in a major traffic jam.
Officials said the concrete was wet which prevented them from reopening all lanes of the bridge.
The left three lanes were reopened to traffic around 8:30 a.m.
Drivers were told to still expect delays around the area.
