To the surprise of many, the upper busway opposite the Arnold Arboretum began being taken apart on Saturday.
Riders had to look for their bus in the temporary lot further down Washington Street. T personnel were on hand to direct riders transferring off the Orange Line.
MassDot notified the community Friday that demolition would begin over the weekend of Oct. 3-5, but contractors are taking down panels two weeks earlier. MassDot hosted its regular monthly informational meeting on Thursday but this weekend work was not explained.
However, Friday's mass email from MassDOT on Casey plans included this sentence: "Also, on Saturday, September 19th from 7AM to 7PM the roof panels on the track side of the MBTA bus canopy will be removed."
