SAN FRANCISCO (KCBS Radio) -- Another headache for the Transbay Transit Center: the path that runs through the rooftop garden needs to be replaced.

The garden remains inaccessible to the public while repairs are made in cracked steel beams in the massive transit hub below. The pathway, made of decomposed granite, winds through the park that caps the transit terminal.

It was only open for about six weeks before the discovery of cracks in supporting beams caused the closure of the transit terminal in September. Small divots had already developed in the pathway by that time, and it has continued to degrade even without any foot traffic.

KCBS and Chronicle Insider Phil Matier reports the cost of the path reconstruction is likely to top $1 million. Work has already started on removing the decomposed granite surface. The replacement path will be made of what Transbay Transit Center officials described as "a cost-effective, easy-to-maintain, durable material".

Meanwhile, crews have started the process of removing temporary support struts under the portion of the transit center than spans Fremont Street.  Work on strengthening the cracked beams is scheduled to be finished by June, but no date has been set for the re-opening of the center.
