The presentation discussed NJ Transit's Main Line Second Track project which involved installing a second track along a section of the Main Line to increase capacity. Key aspects of the project included constructing retaining walls to address variable subsurface conditions, widening the Hazel Street bridge, and building two new through-girder bridges at Main Street and Getty Avenue. The project was completed ahead of schedule and under budget with no change orders or claims.
