Minimizing Impacts to the Community and Commuters: Constructing the District of Columbia's Largest Tunnel Along a Major Urban Artery

摘要

Construction is underway on the District of Columbia Water and Sewer Authority's largest component of its project portfolio in one of the most heavily populated areas of the Nation's Capital. The Northeast Boundary Tunnel is aligned along a major arterial roadway and targeted at relieving areas plagued by chronic flooding due to under-capacity sewers. This paper discusses the processes used to design community and traffic mitigation measures in the design-build contract and the actual implementation of these measures as part of the construction efforts. Focus will be placed on project milestones, mitigation of impacts, and safety.
