NORWALK - Dozens of people gathered at the Maritime Aquarium in Norwalk Tuesday evening to hear the latest on a plan to replace the railroad bridge over the Norwalk River.

The bridge is 120 years old and 20 years beyond its designed life expectancy.

Officials say it is part of one of the busiest rail corridors in the country. They say the Northeast Corridor has about 125,000 passengers passing through the section every day.

Officials say the bridge has gone through mechanical failures in the past and has become stuck in an open position. This has caused some major delays and headaches for commuters.

Officials say construction of the Walk Bridge is expected to begin in 2018.
