Transbay Tube retrofit complete
Submitted By BART
BART passengers traveling through the Transbay Tube will no longer endure single-tracking delays caused by earthquake retrofit work as BART engineers have completed one phase of the important project ahead of schedule.
In March, BART began work installing heavy steel plates inside the tube to make it stronger against an earthquake. BART originally estimated the project to last 14 months, but instead, it took only eight.
ÒWe are thrilled the work was finished early and BART passengers will no longer be inconvenienced from this phase of our larger project to make the tube as resilient as possible,Ó said Tom Horton, group manager of BARTÕs Earthquake Safety Program. ÒWith this phase of strengthening complete, BART will begin planning the next stages of this multi-year effort. All work will be planned to minimize impact to our riders. The result will be a stronger, safer Transbay Tube.Ó
This work is part of BARTÕs Earthquake Safety Program to strengthen not only the tube but also 34 stations, 22 miles of elevated track (including 1,918 support columns) and parking structures and other facilities. The program is on budget.
