Workers have demolished a bridge over a Connecticut highway that was damaged in a fiery crash involving a gasoline tanker truck. The demolition that began Friday is expected to keep both sides of Interstate 95 in Norwalk closed through the weekend and extend a traffic nightmare on the major artery linking New England and New York. Gov. Ned Lamont says the plan is still to reopen the highway on Monday morning. Crews are expected to finish removing the bridge by Sunday morning, and road repairs will be made. The tanker truck burst into flames under the overpass after colliding with two other vehicles Thursday. The cause remains under investigation.
