Demolition will be done through energetic felling, which requires the placement of small charges at key joins of the structure that will break apart and collapse the bridge when charged, the report says.
The bridge opened in 1939, and was originally intended to carry 10,000 vehicles per day. The report says by the time it closed in April, 180,000 vehicles were using the bridge per day.
In April, the structure was replaced by the first span on the new Kosciuszko Bridge. The new bridge features three lanes of traffic in each direction. The second span is expected to open in 2020 and will have five lanes on the Queens-bound side and four lanes with a pedestrian path on the Brooklyn-bound side.
