Over the past few weeks, I've finished the scenery on both shorelines (sorry about the lack of photos, but that must continue for reasons that will become apparent later).
However, I did undertake a cleaning of the bridge (I've been swiffering! 
. The scarcity of 90% isopropyl alcohol (for track cleaning purposes) is an unintended consequence of the COVID-19 pandemic. That meant I had to use 50% isopropyl alcohol. I put that on a swiffer pad, put the pad on the handle, and was able to reach into the bridge to clean it. Turns out there was a lot of gunk on the track. After the cleaning, I covered up the track with some butcher paper. We still have a lot of construction (about 60% of the benchwork) remaining. There will be much, much more dust and dirt flying around.
