Union Station Project Update #4

I’m interrupting my planned sequence of blogs to bring you some breaking news.

Late yesterday afternoon, I noticed a new, shallow trench being dug from the Millennium Bridge along the CML tracks.  During my routine photo-tour around the project today, I bumped into one of Kiewit’s employees.  Just like all the others I’ve talked with, he was very friendly and eager to answer my questions.  The trench turns out to be the start of the light rail station and train platform.  It appears that they finished the digging work a few minutes ago.  Soon, they will start the shoring wall for the LRT platform.  The trench is along the left side of this photo that I took  from the Millennium Bridge at about 1:00 today.

Another new phase of the project is the removal of the granite sidewalk along 16th Street between the Millennium Bridge and Wewatta Street.  Notice the granite slabs stacked on pallets on the left side of the photo.  I’ll talk more about this process in a subsequent blog.

Denver 1973

This is a great photograph. I don’t know who took the photo originally, but I snagged it from the 2007 Auraria Campus Master Plan document, which had included a small version of this photo in the chapter discussing Auraria’s history. With a little help from Photoshop, I was able to extract the image at a high resolution and present it to you today. The Auraria neighborhood and surrounding areas in 1973:

There’s so much here to talk about in this photo.

First, obviously, we have a great view of the Auraria neighborhood (originally the Town of Auraria before the consolidation of Denver City, Auraria, and Highland on April 3, 1860) before the Auraria Campus was created. The buildings that survived the demolition of the neighborhood to make way for the campus were the Tivoli Brewery, St. Elizabeth’s Church, St. Cajetan’s Church, Emmanuel Episcopal Chapel (Denver’s oldest surviving church, built in 1876, and now the Emmanuel Gallery), and the historic homes along Ninth Street Historic Park.

What’s also visible in the Auraria area is the old Larimer Street and Lawrence Street viaducts.  As in-bound and out-bound viaducts, they were one of the main ways to get between I-25 and Downtown Denver. They were replaced in the late 1980s by Auraria Parkway; the viaducts were removed and in their place today are mostly broad pedestrian walkways or narrow streets for local access and RTD busses. The street running in front of  the taller historic buildings where Kacey Fine Furniture, Brooklyn’s, and the Auraria Lofts are today—that was Wazee Street.  Behind those buildings, where the Pepsi Center is now located, were more rail yards. We also get a nice view from this angle of the 13th and 14th Street (Speer) viaducts that I mentioned in my Denver 1961 post. What was neat about those viaducts, as you can see in this photo, was that the out-bound 14th Street viaduct didn’t go elevated until about 14th and Wazee, and it ran along the Cherry Creek side of the Acme and Volker Loft buildings. But the in-bound 13th Street viaduct remained elevated until Larimer, and ran along the southwest side of the Acme and Volker buildings. The two streets then did a clumsy readjustment over Cherry Creek to eventually flow into the Speer Boulevard alignment we have today to the south.

Union Station is clearly visible in this photo, with the big boxy blond brick Postal Annex next door (replaced by the EPA Building and 1515 Wynkoop). What you see behind Union Station to the Platte River—yeah, that area has changed a bit, no?  We also see the old 15th Street viaduct (replaced in the 1980s by the current 15th Street which goes under the railroad tracks and features twin red pedestrian bridges), the old 16th Street viaduct (gone entirely), and, off in the distance, the 20th Street, 23rd Street/Park Avenue, and Broadway viaducts—all replaced in the 1990s/early 2000s.  The bright white grain elevator at 20th and Wazee—that’s where Coors Field is today.

Finally, there are a few remarkable changes in the Downtown area to note. Brooks Tower is there, but its companion building (formerly the Executive Tower Inn and now the Curtis Hotel) is not.  However, the black-glass modern Park Central complex on Block 075 is clearly under construction in this photo. Who would have ever guessed from their outward appearances that Park Central is older than the Curtis Hotel tower? In front of the Park Central site at 15th and Arapahoe is the side of the Central Bank building.

The two blocks of parking lots in the foreground of the Brooks Tower… that’s where the Denver Performing Arts Complex is.  The department store around the D&F tower has been torn down, but the Tabor Center is still a decade off in the future; although the Tabor Center’s other block between Lawrence and Larimer has not yet been razed. On the foreground side of 16th Street (pre-Mall, of course) you can see that the entire block where Writer Square is today has been leveled, as has the half-block to the left where The Larimer condo tower is today. Its neighbor, the blank-walled former-Dave Cook’s-now-Office-Depot building hasn’t been built yet. Also visible are the buildings that were there before Market Street Station was built.

The year 1973 was probably an exciting year in Denver. They were on the cusp of the city’s greatest building boom, probably not unlike how we all felt in 2005. In the next twelve years, from 1973 until the date of the next photo I’m going to feature (1985), over forty towers (yes, you read correctly, 40) were built in Downtown Denver. Now that was a building boom!


Union Station Project Update #3

Various water systems have been a major focus of the project in its early stages for rerouting water lines around the project, for draining surface water, and for keeping ground water from seeping into the bus box hole while it’s being dug.

Last summer, Wewatta Street was torn up for several weeks while water and sewer bypasses were built under the east side of the street. Wewatta Street is now torn up again to remove the original water and sewer lines from the west side of the street and rereoute water through the new bypasses. The picture below is the best shot I could get of that activity.

The bus box hole will be dug halfway across Wewatta Street up to the bypass lines. Eventually, the original water and sewer lines will be rebuilt on the west side of Wewatta over the top of the bus box, and the bypasses will be removed for the continuation of the digging toward the station.

Over the past few weeks, other water and sewer lines have been removed from the bus box location, and a new storm sewer line was built underground around the south and west sides of the bus box. That new line is now being connected to the existing line that runs under 18th Street to the river.

A new surface water collection point was constructed in the center of the site, just to the north of the bus box. It is also connected to the 18th Street storm sewer line. Completion of that collection point was timely for draining last week’s melting snow.

About a month ago, ten dewatering wells were dug around the perimeter of the eventual bus box hole. Ground water will be pumped from the wells into pipes laid on the surface of the ground to four tanks that will treat the water before it is dumped into the storm sewer that leads to the river. Once the water-tight bus box is finished, the ground water pumping and treatment system will be dismantled and removed.

In the following photo, you can see the surface water collection point (lower center), some of the piping that connects dewatering wells (vertical to the right), and the work at Wewatta Street (top).

Union Station Project Update #2

The mid-week snowstorm stopped construction activity for a day and slowed it down for the rest of the week. No dirt has been hauled out of the bus box since Tuesday. However, other activity continues. As you can see in the photo that I took on Friday from the Union Gateway Bridge (the new 18th Street pedestrian bridge), the shoring wall is starting to take shape below and to the left of the light pole. Also, in reference to the picture, new light rail tracks will enter the area from under the left side of the Millennium Bridge. Notice the coal train sitting on the CML tracks at the far right of the picture. The new station will be built between the coal train and the shoring wall.

In case you missed the Denver Union Station Project Authority meeting on Thursday, you can see the presentation here starting on Monday, March 29. Mary Margaret Jones of Hargreaves (the landscape architect) presented various designs for Wynkoop Plaza which is the area in front of the historic station. Final decisions have not yet been made, and they remain open to public input.
