TRENTON - Legislature hearings on September's controversial George Washington Bridge lane closures continued today.

Democrats in the Legislature focused on three executives from the Port Authority of New York and New Jersey to find out why the closures were approved and who called for them. All three who testified said the lane closures were ordered by David Wildstein, who has announced his resignation effective Jan. 1.

The closures were originally explained by Wildstein's superior, Bill Baroni, to be part of a traffic study, but he later said he was not aware of any study being conducted.

Democrats on the panel say they refuse to believe that Wildstein acted alone, and are urging for Baroni to resign as well.

Wildstein did not return any calls that were made to his office requesting comment.

September's lane closures caused gridlock and delays to both residential and emergency vehicles.
