In this May 12, 2005, photo, a portal bridge burns after a fast-moving fire engulfed the railroad bridge, disrupting New Jersey Transit and Amtrak service on the Northeast Corridor. A plan to replace the bridge has pushed forward and could be finished in less than four years — provided about $940 million can be found to complete the project. Amtrak and New Jersey Transit carry between 150,000 and 200,000 people across the bridge each day.
