This photo is from the westbound platform at the
Clark/Lake station. It is an early morning in winter. An
inbound Green Line train with its bright headlights is on the far
side of the junction above Lake and Wells. That crossing is
the most complex and busiest on the system. Traffic through
there is controlled by Tower 18, prominently in view.
There has been much urban rebuilding in and near this part of
downtown in recent years. And downtown has greatly
expanded, with offices and residential development bulging outward
from the Loop on all of its sides.
