Bucks County’s new parking garage, near the courthouse in Doylestown, opens to the public next week. It has 1,200 spaces, and it’s the first part of a new justice center complex that will replace the current courthouse, which is outdated and overcrowded.  The official opening is at 10:00am on Wednesday, June 30.  The next step is tearing down the old 900-space parking garage, along Broad Street between Main and Union, where the new $100 million justice center will eventually stand.
