South Waterfront Construction

I was walking through the South Waterfront on Thursday and was excited to see all the construction going on.  I’m always enthusiastic to see development inside the city rather than in the suburbs, so any work is positive in my opinion.  I think the lack of old architecture is a bane to the health of South Waterfront.  Still, It’s incredible when you consider what this land looked like 15 years ago!  I’m excited to see it fully develop.

Here are photos of the Collaborative Life Science Building and the Portland-Milwaukie Lightrail Bridge:

South of the Collaborative Life Science Building (on Moody) is The Emery, a new residential project by ZGF.  I think the cladding looks wonderful and it fits well against the hill and next to the Ross Island Bridge.  There is so much glass curtain wall construction to be found in the South Waterfront, it’s nice to see the solidity and color in this new project.

Sellwood Bridge Move

On January 19, the 87 year old Sellwood Bridge began a 12 hour move to its temporary new home, a few yards downstream from its original location.  The 3,400 ton structure was slowly pushed north by a network of 50 hydraulic jacks onto five temporary support piers.  Making the whole operation even more complex is the fact that the bridge had to be moved at a skewed angle, with the east end moving 33 feet northward and the west end moving 66 feet.  With the bridge diverting the traffic, work can now begin on its replacement.

Here are my photos and sketches:

St. Johns Bridge and Cathedral Park

I took advantage of the sunny weather last week and visited the St. Johns Bridge.  Because I walked across the bridge on my previous visit, I chose to explored below this time.  Under the bridge on the east side of the Willamette is Cathedral Park.  It’s one of my favorite green spaces in the city because of how beautifully the bridge dominates the landscape.  Walk under the bridge’s span and you will see that the lancet-shaped arches line up all the way across the river (it’s how park got the name “Cathedral”?).

Portland-Milwaukie Light Rail Bridge

The Portland-Milwaukie light rail project is progressing and nowhere is it more evident than at the two towers which are growing out of the Willamette River.  When completed, this bridge will connect the west-side light rail to the new tracks on Grand Ave and the future Milwaukie track.  It will be the only bridge in Portland without auto access.  Two center lanes will be used for bus and light rail, with outer walkways for pedestrians.  Tri Met has a site for more information.  It has a ton of images about station layouts, track routes, etc (awesome!).  Check it out here: http://trimet.org/pm/

Here are my pictures and a notes:

Portland Bridge Swim, Submarine, and Clouds

I walked down the East-Bank Esplanade this morning to enjoy the cloudy and cool July weather and to catch a glimpse of the Portland Bridge Swim.  The Bridge Swim is an annual event in which swimmers travel under 11 Portland bridges as they swim 11 miles up the river (the Willamette River flows North, by the way). The race begins at the Sellwood Bridge and ends at the St. Johns Bridge. The Willamette must be so much cleaner than it was when I was a little kid. In the 90s, I assumed anyone who swam in the river would develop mutant qualities or be eaten by some kind of Superfund river monster…

Here are some shots from this morning. I also made a map of the Portland Bridge Swim’s route:

Gibbs Street Pedestrian Bridge

I visited Portland’s newest architectural addition this weekend!  The Gibbs Street Footbridge opened on Saturday and I was there to try it out.  The footbridge runs below the aerial tram and connects Corbett-Lair Hill district with the South Waterfront. Although it is far less dramatic than the tram, I believe it’s a much more significant addition.  This will finally connect the two neighborhoods which are so drastically divided by the I-5/Macadam/Hood Ave corridor.

The bridge is tastefully done. I’ve seen older renderings which showed much more elaborate designs, but I think the finished product looks better.  The structure consists of a steel box-girder, supported by two concrete pillars, terminating at an elevator tower. I’m a big fan of the use of chain-link for the safety mesh. I’m also happy to see the bicycle tracks built-into the concrete stairs.  It’s such a simple design solution but makes all the difference when you’re trying to carry a bike up or down seven flights of stairs.

Here are my photos, sketches, and diagrams:

Union Station

Union Station is one of Portland’s oldest and most iconic structures. It was designed by Van Brunt & Howe and opened in 1896. The Station is located at the Northern end of the transit Mall, which serves as downtown’s transportation hub, linking light rail, city buses, greyhound, and Amtrak.

Here are my sketches and photos. I’ve created a map of the various rail routes throughout Portland as well.
