The Delaware Memorial Bridge will temporarily close Tuesday, March 26, as a heavy-lift shipping vessel passes between the spans at approximately 11:55 p.m.

The Delaware River and Bay Authority is closing the bridge between 11:45 p.m. to 12:15 a.m. as a precaution and to avoid driver distraction.

The distance from the water level to the top of the cranes aboard the ZHEN HUA25 is 188 feet, 3 inches. Due to tides levels and the Delaware Memorial Bridge's measured clearances, the vessel must travel under the spans during low tide.

Produced by Shanghai Zhenhua Heavy Industry Co in China, the two new super-post- Panamax cranes are destined for PhilaPort's Packer Avenue Marine Terminal.

Once the ship unloads two cranes in Philadelphia, it will deliver another to Wilmington, North Carolina. The bridge will briefly close again on Tuesday, April 2 for the return trip down the Delaware River.
