One challenge on the project is the replacing of the bearings and pin & hanger splices. These replacements must take place in a very detailed sequence in order to maintain the structures continuity during construction while it functions as an active bridge for the traveling public. Another challenge is due to the work taking place over approximately 25 railroad tracks that are in operation 24 hours a day.
