Bonds for the new downtown arena in Louisville could be issued as early as this week. But exactly when that will occur is unclear.The arena authority will meet Wednesday afternoon. Investment bank Goldman Sachs could announce the sale of bonds at the meeting, but authority chairman Jim Host says the bond market is too shaky to guarantee that will happen.βAt this point we are still working on that and hopefully weβll be in a better position of being able to talk about that Wednesday,β says Host.The authority plans a $360 million bond issue for the project. Host says as of Friday the market appeared favorable for the sale.
