Central Artery Team Opens Last $2.6-billion Segment
The third and final tunnel opening this year on Bostons $14.6-billion Central Artery/Tunnel project went as scheduled Dec 20 when officials and workers activated the Interstate 93 southbound lanes.
Opening the $2.6-billion segment now allows traffic to flow both ways through the I-93 tunnel box and over the 10-lane asymmetrical cable-stayed Leonard P. Zakim/Bunker Hill Bridge spanning the Charles River. It also allows final demolition of the existing 50-year- old viaduct it is replacing.
