I made two trips to catch a MLC300 doing HVAC work at a Microsoft server farm building in Spring, 2019: first, second. Each time I noticed that the lanes were reduced on North Avenue under the UP/C&NW tracks that are north of their Proviso Yard. Also, there were cranes north and south of North Avenue by the bridges.
I also noticed that on the west side bridge they still had a C&NW logo on it over the south lanes.
When I visited Proviso Yard in the Summer to get a photo of #1111, there was no construction activity. But I did stop to get a photo of the old logo.
But my hopes were soon dashed.
I did notice the old bridge piers that were peaking out from under the new bridge. So I zoomed in for that photo and left since I could not get any closer to the crane action.
I discovered that Street View went along North while they were doing construction in Nov, 2018. So I'll use their photos.
The old bridge with the C&NW logo is definitely in use because we again see a train on it. In fact, that looks like a coal train. The reporting marks are WEPX. Looking that up in a reference:
WEPX *WHITE EAGLE OIL & REFINING CO. WEPX +WISCONSIN ELECTRIC POWER CO.
WPSX *W. P. STORK REFRIGERATOR LINE WPSX *WESTERN PLANT SERVICES (CALIFORNIA) WPSX +WISCONSIN PUBLIC SERVICE CORP.
Continuing my Street View ride under the old west bridge, I see the old east bridge and the two cranes.
On the east side looking South. Many highway bridges have switched from steel girders to concrete girders. But I notice that railroad bridges still use steel girders.
I also noticed in the street views that there was a man walking along the sidewalk on the south side. I may do another trip to look at those bridges.
On my trip to Proviso Yard, I took a couple of photos of the Lake Street underpass as I waited for the traffic to clear. This was the one place on the trip that I encountered traffic on a Sunday evening.
