Yesterday, I saw cyclists on the north path of the GWB. On further inspection, I saw that the south entrance CLOSED on April 2.
I found the following posted on the Port Authority website:
The south sidewalk will be closed and the north sidewalk will operate in its place from Monday, April 2, 2007 until approximately Monday, June 2, 2007. This operational change is needed to allow for construction that will improve the safety and security of the bridge.
