I-90 bridge’s Link retrofit almost finished

Sound Transit announced on Wednesday that construction crews are nearly done with their work retrofitting the I-90 bridge for East Link. Crews have worked for more than a year to post-tension the bridge’s pontoons.

ST reinforced the bridge to help it carry the load of Link’s tracks, overhead lines, and vehicles. The retrofit also improves the integrity of the bridge in heavy wind and an attendant storm surge, the likes of which sank the eastbound span in 1990.

All the Lake Washington floating bridges use a system of tensioned steel cables to hold the span in place. Construction crews installed additional cables in the pontoons of the I-90 span. The cables, which crews stressed and winched, pull the pontoons closer together, which creates greater load bearing capacity. Altogether, according to Sound Transit’s Zach Ambrose, “crews installed and stressed 1,080,000 feet of steel strand and applied 41,000 pounds of pressure.”

Giant steel structures, called reaction frames, anchor the new cables at both ends. They absorb the force from winching the steel cables, and whatever event that might stress the structure. Each of the ten reaction frames weigh about 17,500 pounds.

The structural work is finished. Crews are removing equipment from the pontoons and grouting the housing of the cables, to prevent water corrosion. After that work is done, construction of the guideway can start.

New Shuttle Pilot Serving the Waterfront

The Downtown Seattle Association is running a two-month “Waterfront Shuttle,” starting August 1st and running through October 1. It is free to ride and serves the stops shown on the map.

It is clearly aimed at tourists, although this month is a little late to start serving that market. It runs from 10am to 8pm, seven days a week, and hits many of the obvious tourist spots. The literature suggests people use the shuttle to access waterfront businesses after parking elsewhere downtown.

The money comes from WSDOT, as mitigation for their endless project on the waterfront. This year’s operation is a pilot to develop service concepts for future service should a long-term funding source arise. WSDOT’s mess will continue through 2019, so if the pilot is promising we may see another year of it. The DSA contracted with MTR Western to operate the buses.

The stated headway is “approximately” every 25 minutes, with no attempt to match any printed schedule. However, the end-to-end trip time is (at best) also 25 minutes. As 3 to 4 22-seat vehicles simultaneously serve the route at different times of day, the headways are often quite a bit shorter than 25 minutes. Although there are no real-time arrival information signs or data feeds, today DSA deploys “concierges” at major stops to communicate with buses on the radio.

When I first read about this service concept, I was skeptical that a 25-minute headway on a short-haul line would attract many riders. The DSA says that a total of 4,957 riders used the shuttle in the first two weeks, and (anecdotally) in peak hours these shuttles are sometimes standing-room-only. 35 riders per hour isn’t bad for new service with some of the limitations above; it would be great to see what a properly provisioned bus line could do.

Hearing About Congestion Pricing? Ask About Transit Investment.

It’s safe to say that Seattle transit advocates are uncertain about Mayor Jenny Durkan’s commitment to transit.  The fate of the Center City Connector continues to grow murkier. The Mayor told a large, powerful coalition of CCC advocates to talk to the hand.  Several transit and safe streets projects throughout Seattle have been delayed or canceled (although others have proceeded on schedule).  Funding shortfalls shrank and delayed RapidRide projects, while leaving expensive auto-centered projects like the Lander bridge unaffected.  One Center City lost many of its transit priority ideas in becoming Imagine Downtown.  Throughout all of this, the mayor’s office has not said much about transit, except occasionally to point out its numerical necessity in the most general terms.

The mayor, though, has continued to talk up one transportation proposal: congestion pricing.  Often called “decongestion pricing” by advocates who want to clarify its goal, the policy charges car drivers to enter central city areas, with higher charges during the most crowded hours. (Other policies such as HOT lanes and variable bridge/tunnel tolls are also forms of congestion pricing, but aren’t what the mayor is proposing.)  Central city congestion pricing has been implemented in London, Singapore, and Stockholm, but nowhere in the United States to date.  Among U.S. cities, only New York has seriously considered it, so far without action.

Urban Mobility in Seattle: A recipe for success any city can make their own

Route 41 entering the express lane ramp

By ANDREW GLASS HASTINGS

Seattle has been successful in redefining urban mobility, but our recipe for success doesn’t have to be unique. Like any good cook who starts with the fundamentals of a solid recipe, then adjusts the ingredients to fit different tastes and dietary needs, each city can adapt elements of successful mobility strategies to best meet their own needs.

Over the past few years Seattle’s recipe to redefine urban mobility has include investment in transit service, adoption of TNCs (Lyft and Uber), growing the car share market, and experimenting with bike share – all of this while Seattle experienced the highest increase in transit ridership of any major city in the US. We are growing the mobility ‘pie’ with more choices to get around than ever before.

Here are a few of the ingredients to consider:

Easy Fixes Not Deployed for 3rd Ave

The Seattle Department of Transportation and King County Metro recently announced several useful measures they will take to improve bus priority on 3rd Ave.

3rd Ave has the densest collection of bus routes in the state, and is pretty much totally packed with buses maneuvering around each other during peak hours. Every measure taken to speed up this armada pays for itself many times over in savings for Metro and the ability to redeploy the saved service hours. Indeed, saving service hours on 3rd Ave is about the only way Metro can add more service while waiting for an eighth base to open. Metro had to turn down some service-hour funding from the City in part because of this practical ceiling on deployable service.

The clearest solution for 3rd Ave remains red paint, designating a ban on non-permitted vehicles 24/7/365. However, various downtown blocks still have parking garage entrances, loading dock entrances, two-spot parking cutouts, or a whole lane of parking. Nevertheless, many blocks have little reason for cars to be there beyond driving straight through without stopping. These blocks ought to be able to be painted red, without political pushback:

Upzone the ‘Burbs

New apartments just steps away from the future downtown Redmond light rail station.

Mike Rosenberg has another excellent piece in the Seattle Times, examining why housing construction in suburban King County has slowed while Seattle remains red-hot.

Overall, Seattle housing construction has grown 130 percent this decade compared to the average over the prior three decades, while housing development in the suburbs has dropped 43 percent from its historical average.

Add it all up and the county as a whole is actually on pace for a slight decline in the overall number of homes going up here this decade, despite Seattle’s building frenzy.

King County doesn’t have many large developable tracts of land left for single-family development, so developers have pushed into Snohomish and Pierce. But there’s plenty of opportunity for multifamily infill development.

As we’ve noted, some suburban cities are enacting development moratoria as they rewrite their zoning codes in the face of renewed growth. On the other end of the spectrum, Kenmore and Bothell are growing along the future 522 BRT corridor. Redmond is adding tons of new apartments in anticipation of light rail.

Despite all that growth, King County’s suburban cities still aren’t building nearly as much multifamily housing as they were in the 1980s and 1990s, according to the article.  As we’ve covered, growth is centralizing in Seattle and Bellevue, despite the PSRC’s plans to put more people and jobs in farther-flung suburbs.

With greenfield land running out, the next step – short of expanding the urban growth boundary – is to figure out how to do missing middle-style infill in the inner-ring suburbs.  That’s no small challenge given the preponderance of cul-de-sacs, lack of sidewalks, and infrequent transit service.  Fortunately light rail is coming, along with improved bus service, and there is no shortage of ideas on how to retrofit suburbia.

Suburban retrofits, however, require political will and currently there’s no political appetite for increasing density in single-family neighborhoods among Eastside electeds (there’s barely appetite for it in Seattle!). Nonetheless, more infill in the suburbs would be a huge win for regional equity. Adding housing capacity in these amenity-rich single-family neighborhoods (where zoning typically maxes out at just 3-5 units per acre) will make them more attractive to a new generation that wants more transportation options than the Eastside’s strip mall-centric built environment can currently provide, while relieving development pressures on lower-income neighborhoods in places like Seattle.
