Lean, Innovative, and Unique Project Solutions

This project was challenged by large amounts of wetlands, the York River Bridge Crossing, heavily traveled U.S. Route 1, and endangered plant species. The Cianbro team employed various construction methods in order to get the job completed on schedule, with minimal interruption to traffic, and resulting in positive environmental compliance.
