Central Subway Project Manager John Funghi leads Mayor Edwin Lee on a tour of the completed tunnels
Congratulations to the Central Subway Team for achieving an Award of Merit for best transportation project of 2015 from Engineering News record, a weekly magazine highlighting the construction industry. The award was given for the completion of the Central Subway Tunnel. The Central Subway Tunnel Project was cited for completing an intricate project on time and within the approved budget.
A method called deep tunneling was used to build the tunnels. Two tunnel boring machines, named for San Francisco Legends Alma Spreckels and Dr. Margaret “Mom” Chung, were used in the construction. Use of these machines enabled the work to be finished with less surface disruptions and reduced utility relocations.
The Central Subway Tunnel completion was a major milestone for the project. When the Central Subway is completed, T Third Line trains will travel mostly underground in the 2 mile tunnels from 4th Street to Chinatown, bypassing heavy traffic on congested 4th and Stockton Streets. Our team is very proud to have been recognized by ENR for this achievement.
The Central Subway Team looks forward to more success in 2016. We wish San Francisco a very happy and healthy holiday season.
