The old bridge just wasn't designed for any expanded capacity. The new PB should have been designed to eventually have a 2nd deck & a provision for rapid rail transit. The new bridge should have been planned to open with a 3rd lane each way for bus & HOV. Apparently, it's better to funnel everything into 2 lanes each way. Good bike & foot paths, but no need for bus & HOV lanes at this time. WTH?
