TRENTON - As New Jersey readies for another potential storm, state lawmakers want to know more about what went wrong with the cleanup of the after-Christmas blizzard.

The state Assembly Transportation Committee has asked to hear from Transportation Commissioner James Simpson at a hearing later today. The panel has also summoned officials from the State Police, Turnpike Authority and mayors whose towns were hardest hit.

The Dec. 26 blizzard dumped nearly 3 feet of snow in parts of the state, with the shore and some northern areas hardest hit. More than 550 vehicles had to be removed from New Jersey roads, which went unplowed for days.

Assembly Transportation Committee Chairman John Wisniewski says he'd like a detailed account of what went wrong at the operational level and how mistakes can be avoided.
