The $2.2 billion dollar facility had been open for just six weeks when it was closed because of cracks found in two steel girders on Sept. 25, 2018 [See “Future home of CAHSR closed following discovery of cracked beam,” Trains News Wire, Sept. 26, 2018].
While officials with the Transbay Joint Powers Authority have not yet set an opening date, the Chronicle reports repairs to the cracked beams, and a matching but unbroken pair elsewhere in the structure, are expected to be completed in the first week of June. However, an independing review committee could determine that additional inspections or repairs are needed, which would extend the closure.
The three-block-long structure, which features a rooftop park that has also been closed, opened in August 2018. To repair the damaged girders, workers will bolt 2-inch-thick steal plates on both sides of the flanges of each girder, a process requiring some 224 bolts.
