More work in Michigan City this week. This view is looking east from just west of Wabash St. Note the new streetlights on both sides of the ROW. The arm on the right hand side is for the replacement traffic light. (The concrete base in the foreground is for a catenary support.)

Over at the diamond Amtrak has the new eastbound signal in place ... shown from both directions with an arrow over the new signal. The new signal is bagged and not in service.

Interesting using a steel stabilizer/cross member attached to wood poles.
I don't recall seeing that done before.

There are dozens and dozens of that type of portal structure on the South Shore, especially in the Wilson segment. There are a bunch of new ones around Powers, both west of US12 and the curve at EE Powers.

Very common at crossovers and (as you note) the Wilson segment. The west end of Wilson was the "Ideal" section of South Shore with iron posts and cross beams. Elsewhere it was hard to find a catenary support that wasn't wood before the constant tension wire was installed a few years back. Steel beam poles were needed to support the weight of the counterweights and normally just the counterweight.

Certainly a lot more wooden poles than steel along the length of the line ... with crossbeams on wooden poles. (The only place I recall seeing complete steel catenary supports was at Dune Park, one on the bridge near Miller, in East Chicago along the toll road and Hegewisch at the station.)

Waverly Rd (1st road west of Dune Park) received a second track at the crossing last week. A week from now construction will be at the entrance to Dune Acres at Mineral Springs Rd. This road is the only open entrance to Dune Acres so traffic will be maintained across the tracks while new track is installed. Apparently a "shoo fly" for road traffic. As posted on the project web site:

"Beginning 9/26 for 5 days, changes to traffic patterns at Mineral Springs Rd start. During this time, new additional track will be installed to the North. In order to maintain public traffic, a run around route next to the current road will be installed. This run around route will utilize a temporary traffic light to facilitate alternating northbound and southbound traffic. Short delays may be encountered due to alternating vehicular traffic."

Lafayette St will close for 14 days starting next week and Sheridan Ave will close for 40 days (with the reopening of Willard St).
The project web site also reports a 19 day closure of Washington St will follow the reopening of Wabash St next week.

This week's progress on 11th St at the new station. Raise the roof and get ready for the new track.

The white tubes are for drainage along the tracks.

At the east end of the track 1 platform bases for light fixtures are in place.

What is your favorite color? NICTD and the city are picking colors for the brick and the wall between the tracks and traffic on 11th St.

Wabash St not quite ready for traffic. A better look at the traffic signal supports mentioned last week.

And off at Dune Park the first segment of the new Track 2 is in place. Note that it is in the final position. There will be a wide spacing between track 1 and track two to allow for the new gauntlet on track 1 and to pass around the bridge support to the west of the station (SR49). The catenary supports will be replaced with longer cross beams. The new bases can be seen to the left of the existing supports.

It looks like paving is a behind so consider the dates given last week for street openings (and related closings) delayed. Willard St, Wabash St and Oak St need to be paved and opened before Sheridan, Washington and Lafayette (respectively) can close. There was paving equipment lined up at Ohio St at the fire station. I saw no sign of preparations for the traffic light at Mineral Springs so that may be delayed as well.
