The objective of Boston’s Central Artery/Tunnel (CA/T) Project is to ease the congestion of approximately 190,000 vehicles per day traveling through the city of Boston. This objective is being achieved through the total reconstruction of Interstate Highway I-93 as it passes through the heart of Boston, together with the extension of Interstate I-90 from its terminus at I-93 just south of downtown Boston to Logan International Airport in East Boston. The Artery replaces an elevated six-lane highway that opened in the late 1950s and originally carried approximately 75,000 vehicles per day. The focus of this article is on two transition structures and ramps in the C09C2 Construction Contract: the I-93/I-90 Interchange Ramps and Surface Restoration at Albany Street, where shot-crete facing has been implemented as a facing system for lightweight embankments.
