How Morton Salt's Elston Dock on Chicago's Near North Side was built in 1929-30, its design by a noted architecture firm, and the 2014 wall collapse that ended its salt operations.

## Key Takeaways

- The Elston Dock was a purpose-built, fireproof salt storage shed designed to handle enormous salt piles.
- The 2014 wall collapse was a turning point that led Morton to end salt operations at the site within a year.
- The building's location and design reflected Chicago's river-based shipping, leather industry, and the company's 1920s relocation.

## What the video covers

- The Morton Salt building near Division Street on the Kennedy Expressway was known for its roof with a girl-in-yellow-dress salt logo.
- On December 30, 2014, a wall burst open and tons of road salt spilled onto a neighboring car dealership, and Morton shut down salt operations there within a year.
- The Elston Dock replaced Morton's earlier warehouse at the mouth of the Chicago River, which was damaged by fire in 1927 and displaced by a planned bridge.
- Construction began in 1929 and finished in 1930 on the site of an old tannery in Chicago's leather district, since tanners were major salt customers.
- Graham, Anderson, Probst, and White, the firm behind the Wrigley Building and Union Station, designed the building.
- Fast-curing concrete allowed heavy salt trucks to use the pavement after only four days.
- The interior was a column-free shed where salt arrived by barge and conveyor, then was dropped into piles along the length of the building.
- Reinforced concrete lower walls, a brick upper wall, and buried steel tie rods resisted the outward pressure of the salt piles, and the shed was made fireproof after a 1903 warehouse fire.
- The Morton company dates to 1848, and Joy Morton, son of Arbor Day founder J. Sterling Morton, later founded the Morton Arboretum in 1922.
- The video also closes with thanks to viewers and Patreon supporters.

## Questions about this video

What happened to the Morton Salt building on December 30, 2014?

A wall burst open and tons of road salt poured out onto the car dealership next door. Morton shut down its salt operations at the site within a year.

Why did Morton move its Chicago salt warehouse to Elston?

A 1927 fire damaged the original warehouse on a pier at the mouth of the Chicago River, and the city wanted that spot for a new bridge. Morton relocated upriver, and construction on the Elston Dock began in 1929.

Which architecture firm designed the Elston Dock?

The firm Graham, Anderson, Probst, and White designed it. The same firm was behind the Wrigley Building, Union Station, the Merchandise Mart, and the Shedd Aquarium.

Speaker A

If you've driven into the city on the Kennedy, you know exactly where she is, near Division Street, up on a giant roof.

00:16

Speaker A

A little girl in a yellow dress, umbrella up, pouring salt in the rain.

00:26

Speaker A

For generations of drivers, that roof meant you were almost downtown, but most people never knew exactly what went on underneath it.

00:40

Speaker A

On the afternoon of December 30th, 2014, Chicago got a look.

00:48

Speaker A

A wall burst open and tons of road salt poured out onto the car dealership next door.

00:57

Speaker A

Within a year, Morton had shut down its salt operations there.

01:15

Speaker A

So, what was this building actually for?

01:22

Speaker A

And how did it end up as one of Chicago's newest concert venues?

01:29

Speaker A

Morton called it the Elston Dock.

01:39

Speaker A

Salt came in by boat.

01:54

Speaker A

It got stored in enormous piles, got packaged, and went back out by rail and truck all over the Midwest.

02:05

Speaker A

Before Elston, Morton's Chicago warehouse sat out on a pier at the mouth of the Chicago River, right about where Lake Shore Drive crosses the river today.

02:10

Speaker A

In 1927, a fire damaged that warehouse.

02:22

Speaker A

And the city wanted the spot anyway for a new bridge to carry the outer drive across the river.

02:37

Speaker A

So, Morton moved upriver.

02:49

Speaker A

Construction on Elston started in 1929, and the complex was finished in 1930.

03:04

Speaker A

And the location made sense.

03:21

Speaker A

The land had been part of an old tannery, right in the middle of Chicago's leather district.

03:40

Speaker A

Tanners were good salt customers because salt is how you cure a hide.

03:55

Speaker A

To design it, Morton hired Graham, Anderson, Probst, and White.

04:06

Speaker A

That's the same firm behind the Wrigley Building, Union Station, the Merchandise Mart, and the Shedd Aquarium.

04:16

Speaker A

And here they were designing a shed for salt.

04:25

Speaker A

Morton was in a hurry to open.

04:42

Speaker A

So, the dock got a special fast-curing concrete pavement that could carry heavy salt-filled trucks after curing for just four days.

05:01

Speaker A

Inside, the big shed is basically one giant room with no columns.

05:18

Speaker A

Salt came off the barges and rode a conveyor up into that raised strip along the top of the roof.

05:34

Speaker A

From there, workers could drop it anywhere along the length of the building, and it poured down into piles on the floor.

05:50

Speaker A

That raised strip also had windows to let in light and air.

06:08

Speaker A

A pile of salt that big doesn't just sit there.

06:23

Speaker A

It leans on whatever's holding it in.

06:41

Speaker A

So, the lower walls were built out of reinforced concrete with a brick wall above.

06:57

Speaker A

Steel tie rods were buried under the floor to keep the walls from spreading apart.

07:08

Speaker A

The shed was also built to be fireproof.

07:24

Speaker A

Back in 1903, a giant wooden Morton warehouse in South Chicago had burned to the ground.

07:36

Speaker A

And that logo is older than the building.

07:50

Speaker A

The company traces back to 1848, when a salt business opened a sales office in Chicago.

08:06

Speaker A

In the 1880s, a young man from Nebraska named Joy Morton bought in.

08:22

Speaker A

And eventually, the business carried his name.

08:35

Speaker A

His father, J. Sterling Morton, started Arbor Day.

08:51

Speaker A

Joy loved trees, too.

09:03

Speaker A

In 1922, he established the Morton Arboretum on his land out in Lisle.

09:19
