In the last few days, the plates covering the track construction ("outbound track") crossing Broad Street (ie. between the Stadium and the DL&W Broad Street Station) were removed, exposing a paved grade crossing.
I've noticed some of the "brackets" (sorry, don't know the technical term) being installed on the new catenary poles in the vicinity of the NJPAC station. These look to be perhaps aluminum metal arms from which the atcual trolley wire will hang.
Work is also well along on the "inbound" track crossing of Broad Street down by Lombardy Street. This is where the inbound cars will make a 90-degree left turn from the (effectively) southbound curb lane of Broad Street to the south side of Lombardy street. This crossing is also being done at night and covered with steel plates during the day.
The crossing at the north end of Washington Street is now open (where it meets Broad and Bridge streets), and judging from the congestion I see in the evenings, the new configuration is not as good (for auto traffic) as the old configuration. There used to be an extended green for north bound Washington to northbound Broad street turns, and this has been eliminated due to the Light Rail.
