EDGEWATER — To most, the concrete slab sitting at the end of an alcove outside the Edgewater Beach Apartments looks ordinary, but to at least one group, it's legendary — worthy of city landmark status, even.

Edgewater Beachwalk, a group of residents who advocate for the neighborhood's parks and historical features, wants to see the last remaining North Side portion of a sea wall from 1934 saved by city officials.

The nonprofit said they want Ald. Harry Osterman's office to request to the City Landmarks Commission to save the portion of the wall, which 82 years ago served as the protector between Lake Michigan and Edgewater's shores.

Today, the sea wall looks far from significant: At the base of the pink Edgewater Beach Apartments, 5555 N. Sheridan Road, it sits, partially serving as a barrier for a small dead end street, but mostly completely innocuous to those passing by.

But until the mid-1950s, its presence was essential.

Old aerial photos and postcards show how the shoreline used to swerve in between Foster and Bryn Mawr, hugging the side of the Edgewater Beach Apartments — right where the last piece of the sea wall stands today, marking the beginning of the Bryn Mawr Historic District.

Before 1950, Lake Shore Drive's northernmost exit was at Foster Avenue, just south of the famous hotel.

But during that decade, it was expanded first north to Bryn Mawr Avenue, where the sea wall and the Edgewater Beach Apartments sit, before being completed at Hollywood Avenue in 1958.

In fact, it was Lake Shore Drive's expansion through what was once the hotel's private beach that helped eventually lead to the building's downfall.

Walking under the overpass now at Lake Shore Drive and Bryn Mawr Avenue, a sparkling tiled collage displays colorful mosaics along side bits and pieces of the neighborhood's history — including a plaque from when the drive was built in 1954.
