Going underground: Waterproofing on Boston's CA/T project

Research output: Contribution to specialist publicationArticle

Abstract

The Central Artery/Tunnel Project (CA/T) is the name for Boston's road construction project, which will eventually replace the aging Interstate 93 (I-93). Almost half of the project is currently being constructed in tunnels, with engineers relying on innovative waterproofing solutions to ensure that Boston traffic is kept safe and dry. By going underground the Massachusetts Turnpike Authority has room to expand the highway in the downtown area, plus vehicles can still use the elevated Central Artery while construction takes place. This article describes the road construction project and the solutions found to ensure the tunnel is waterproof - these include spray-on polyurea and polyvinyl chloride (PVC), high density polyethylene and bentonite.
