#I90to1 keeps on truckin'

by Bart Treece

Something has been missing from the morning commutes this week, where westbound I-90 has been reduced to a single lane near Bellevue Way for expansion joint replacement. Traffic has moved relatively smoothly so it’s only natural to ask, “Where are the foreboding traffic tie-ups the clairvoyants of the commute have dubbed, ‘Carpocalypse?’”

The smooth sailing on the expressway and throughout the Eastside and Seattle area can be attributed to you, the commuter. You are doing your part in keeping regional traffic moving during construction. The proof is in the numbers. If you’re ready to get your inner traffic geek on, here you go.

Follow the red line on this graph which shows the commute beginning earlier on Monday, and then holding steady throughout the day, effectively spreading the traffic. Drivers left for work earlier, with the single westbound I-90 lane carrying nearly double the number of typical vehicles in the 4 a.m. hour. By 7 a.m., the peak hour of diversion, westbound I-90 was carrying nearly 60 percent fewer cars and trucks. 


With folks diverting to other routes or staying off the road, it allowed drivers to squeeze into a single lane approaching the construction zone. Travel times from Issaquah to Seattle peaked at 35 minutes. So, even though it looked like a small backup approaching, it was still a slog.


Construction
The toughest part of the construction work is welding the two halves of the expansion joints that equal 82 feet. This began at 6 a.m. today, and could take up to 30 hours. After the work passes a series of tests, concrete will be poured in to seal the joint and will need time to harden. To get an idea of why this work needed to happen, here's a look at one of the expansion joints the contractor pulled out.



These circles show the cracks in the steel, and there's not much keeping it together.



With previous closures, we've seen drivers return to their old habits after a few days, which results in longer travel times and bigger backups. Hopefully, everyone will keep doing what they've been doing so come Friday, life can return back to normal.



I-90 closure: Work progresses, weekday traffic to be tested

by Mike Allende

Our big westbound I-90 expansion joint replacement project started Friday night and work throughout the weekend has gone well with the project remaining right on schedule.



As of Sunday morning, contractor crews had replaced half of two of the huge expansion joints at the East Channel Bridge and were putting down concrete over the new joints. Still to come are the removal of the other half of the old joints, installation of new joints, a 30-hour welding job, and more concrete pouring.

The concrete needs about 12 hours to cure but workers will be monitoring it this afternoon. The concrete needs to reach a strength of 2,500 psi (pounds per square inch) for traffic to go over it. Whenever that happens, we’ll be switching the work zone to the other side of the highway to work on the other half of the joints. That is scheduled to happen around 9 p.m. Monday morning drivers will see traffic moving through the work zone in the Phase 2 configuration.

Phase 2 - Monday - Friday morning














Traffic
From a traffic standpoint, things have been great! We saw no significant slowdowns on westbound I-90 Saturday despite the Sounders match and traffic continued to flow freely on Sunday for people headed into Seattle for the Bite of Seattle or other events. Travel times from Issaquah to Bellevue were about 11 minutes, and about 16 minutes to Seattle.


 
Monday, of course, is going to be a different story. Even with some people adjusting their plans, telecommuting, taking vacation, we’re going to see significant backups. There’s no way around it. Definitely consider alternate routes but even with that, leave as early as possible. I can’t stand stressing out being late, so leave early. People have been asking for advice and leaving early is really the best I can give you. This will also affect other travel routes, such as I-405, SR 520 and even I-5 in Seattle. Your weekday commute will begin earlier and last longer.

#I90to1 Tweets
We’re adjusting our scheduled here in the Traffic Management Center as well. Morning Guy will be in at 5 a.m. and is on point until 2 p.m. monitoring traffic and updating people on our @wsdot_trafficTwitter handle about what’s going on westbound I-90 (and throughout the region). Afternoon Gal takes over at 2 p.m. and will be here until 8 p.m. all week. If you’re a Twitter user please check in with us as we want to get you the best, most timely information to help with your commute. Use the hashtag #I90to1.


And don’t forget, you can also find travel times and check out our traffic cameras and real-time traffic map so you have an idea of what you’re headed into. This work week is going to be a challenge but stick with us and we’ll keep getting information out so you know exactly what’s going on. Want to know more?

High-flying jets of Seafair, mean closures on the ground

Even though the Blue Angels are not flying over Seattle this year, there will still be closures of the Interstate 90 floating bridge while the Patriots Jet Team takes to the skies.

Similar to when the Blue Angels practiced and performed for Seafair, the I-90 floating bridge will still close to drivers, cyclists and walkers. The Federal Aviation Administration requires a Safety Zone for the area below the performance. We call it “The Box,” but really it’s more like a few rectangles crossing over each other. The northern part of the box covers the I-90 floating bridges, which is why they are closed during performances by both the Blue Angels and the Patriots Jet Team.

Traffic
Some minor changes from years past, the closures on I-90 will take less time, and there is no Thursday practice, therefore, no Thursday closure.

Here’s the schedule:
Friday, Aug. 2:  1:15 p.m. - 2:40 p.m. (Practice)
Saturday, Aug. 3:  1:15 p.m. - 2:40 p.m. (Full show)
Sunday, Aug. 4:  1:15 p.m. - 2:40 p.m. (Full show)

Additionally, several ramps will be closed at that time. The I-90 express lanes will also be closed from 12:30 to 3 p.m. each day, but are available in the event of a medical emergency that requires a trip to the hospital. Just call 911.

SR 520
The State Route 520 bridge will remain open for traffic and tolls will be collected according to the rate schedule. Good news for drivers, the bridge will not open for any boats during Patriots Jet Team flights. The bridge will be busy. If you need to take a cross-lake trip while the Patriots are in the air, just plan ahead. Outside of those times during Seafair weekend, the east navigation channel will be open to boats up to 59 feet, which should reduce the number of marine openings.
Whether you’re heading out to enjoy Seafair festivities, or just plain going somewhere else, remember to plan ahead and know before you go.

Seattle is a happening town...



by guest blogger Mike Allende
…..and this weekend, well, there’s going to be plenty happening!

Big events at CenturyLink Field, the Washington State Convention Center and a foot race from the Seattle Center to Fremont could draw up to 63,000 people into the city. Knowing that, our contractor crews will work around the big events to push forward on important safety and pavement repair projects on Interstate 5, the West Seattle Bridge and the Alaskan Way Viaduct.

So with three events happening, why do we have three significant closures on the same weekend? Great question!

Unfortunately, as our years are currently constructed, there are only 52 weekends available and a ton of maintenance and preservation work to get done. Closures aren’t fun for anyone, but neither is poor pavement. We have several more large projects this summer and it’s all vital. We’ve been working since the first weekend of January to try to get it all done this year.

To try to make this a little easier, we have a few tricks up our sleeve. First, we’ve got a detour route mapped out for the West Seattle Bridge/I-5 ramp closure. We’ll also be driving it during the closure to see it needs tweaking. We’ve also worked with the City of Seattle to adjust the signals on the detour route.  For I-5 drivers, we’re keeping the express lanes open southbound all weekend.

Make sure you plan ahead this weekend. The best thing you can do is plan ahead. If you’re if need to head south on I-5, wait until after 10 a.m. Wherever your travels take you, know before you go.  Stay plugged in, check the Seattle Traffic page, our WSDOT mobile app.


So, what exactly is happening? Here you go:
·         Thursday night to Sunday morning: Three out of four lanes of southbound I-5 from 65th Street to the Ship Canal bridge will be closed as crews working for the Washington State Department of Transportation replace concrete panels and do some pavement grinding. The southbound 45th/50th Street off-ramp will also be closed. Closure times will be from 10 p.m. Thursday to 5 a.m. Friday, from 10 p.m. Friday to 10 a.m. Saturday, and from 10 p.m. Saturday to 10 a.m. Sunday.
·         Friday night to Monday morning: The West Seattle Bridge ramp to southbound I-5 will be closed from 10 p.m. Friday to 5 a.m. Monday as crews replace three expansion joints. Drivers will still be able to reach southbound I-5 by using lower Spokane Street or can get off at 4th Avenue South and follow a short detour.
·         Saturday and Sunday: The Alaskan Way Viaduct will be closed for its semi-annual maintenance from 6 a.m. to 5 p.m. Saturday and from 6 a.m. to noon Sunday.
 

Whew!

But there’s more:
·         Sounders: The Seattle Sounders play their season-opener at 7:30 p.m. Saturday against the Montreal Impact at CenturyLink Field and could draw nearly 40,000 fans.
·         Hot Chocolate: The Hot Chocolate Run – a new foot race – will take place Sunday starting at 6:45 a.m. The race starts at the Seattle Center, goes through parts of the north end of downtown, across the Aurora Bridge and into Fremont. The race could draw more than 3,000 runners.
·         Comicon: Emerald City Comicon runs Friday to Sunday at the Washington State Convention Center and expects to draw 20,000 people.


We will have more big closures coming up. With the Sounders and Mariners starting and the usual amount of Seattle fun, this weekend is a great chance to prepare. All of the work is going to lead to better commutes for everyone. We’ll do our part, and with your help, we’ll get through these projects with as minimal of headaches as possible.

Cheers and jeers for new traffic cameras


Our traffic cameras have kind of been hot news in recent months. We’ve brought many new cameras online along I-5 in Tacoma and Everett, and announced many more will go live later this year near Bellingham. While it’s exciting news in many respects, we’ve also received a fair amount of criticism.

People wonder where we’re getting the money for all these cameras, and want to know how we can justify spending it this way during such hard economic times.

The most basic and simple response to part about where the money comes from is that there are state and federal gas taxes that generate revenue every day specifically for transportation improvements. But that’s probably not answer you’re looking for. The real story is a little more complicated.

If we step back for a moment and take a big-picture look at our highway improvements, we have to realize that we can’t build our way out of congestion. It’s just not financially feasible on a number of fronts. It’s unaffordable from a real estate perspective, environmental perspective, construction perspective, and even a long-term maintenance perspective - especially when our budget is declining just like everyone else’s.

Knowing that we can’t afford to build our way out of congestion, we have to ask ourselves, “What can we do to make better use of the existing roads and lanes we already have?” One of the strategies we believe that has some serious merit is making better use of information technology. That’s where the cameras come in.

These cameras are vital to us, to the State Patrol troopers who respond to collisions, and to the traffic reporters who report what’s happening on the roads every day.

They give our maintenance crews, fire departments and law enforcement personnel the tools they need to respond to incidents as quickly and efficiently as possible. We can better coordinate our response and get the roadway open faster.

The cameras also keep drivers informed so they can avoid delays. Drivers can check the cameras and travel times to get a much clearer picture of how I-5 is looking before they leave their homes or offices.

Traffic cameras are just the tip of the iceberg, too. They’re part of a much greater, more expansive network and plan to bring better, more reliable travel information to drivers.

Yes, the traffic technology is expensive, but it costs a mere fraction of what we would spend to try and build our way out of congestion. Traffic cameras are just one way we’re using our existing highway infrastructure more effectively and efficiently.


What's that noise?

When John from the Ravenna neighborhood e-mails me at 2 a.m. saying pavement grinding work on I-5 in Seattle sounds like “airplanes landing in [his] neighbor’s backyard,” I decide to check out the noise myself. I don’t see any crash-landing Boeing jets, but it sure does sound like it.



To get a good idea of how loud it is, listen to this video with your headphones on. I shot this video at midnight 200 feet from I-5 near John’s house at NE 72nd Street.


Pavement grinding is that loud.

No question about it, grinding down 40 years worth of battered, rutted concrete is noisy. However every night our grinders are out there making noise, our highway is getting safer for drivers. The stacked, circular, diamond blades create a textured, corduroy pattern that improves traction for drivers and helps keep standing water off the road, preventing collisions.

During the past few months folks like John have put up with a lot of construction noise on I-5.


The noise started back in February with screeching concrete saws ripping out crumbling concrete panels in the snow (photo, right).

In the springtime residents endured pavement grinders grinding out rutted concrete 24 hours a day all weekend long.


Neighbors enjoyed a reprieve in early summer while crews working for WSDOT shifted their schedule to finish another WSDOT pavement grinding job in the eastern part of the state.


From the sound of things, the crews are back in town. We are grinding down portions of I-5 in both directions from just south of the Ship Canal Bridge to NE 145th Street in Shoreline. We're running at least three grinding machines at the same time to complete the project as fast as possible. Depending on where you live we will finish up the grinding by the fall, a month or so later than we had earlier thought.

Most of the folks I’ve chatted with about the project understand the work needs to get done. They want to know when we will be working near their home and what they can do to block out the loud noise robbing them of sleep at night.



I-5 neighbors can check the site to see where grinders will be working that week. It takes one of our grinders about 10 minutes to grind 60 feet of concrete four feet wide*. The average property lot along I-5 is between 50 and 60 feet wide. This means that if the grinders are working directly near your home, you will hear the noise ramp up and then ease off over a period of about an hour as the grinders move down the highway and away from your area.


I empathize with neighbors and will personally mail free earplugs to anyone who requests them. These earplugs are the same type of ear protection our pavement grinding crews use so there is a good chance they will block out more noise than average earplugs you may find at the corner store.

Finally, I want to thank all those living along the freeway for your patience and understanding while we smooth out nearly 20 miles of wheel ruts, cracks and uneven pavement.


When the work is finished everyone who drives this stretch of road will breathe a sigh of relief from a smoother ride, improved traction and a safer highway.

*Each lane is 12 feet wide, we will grind across all lanes of I-5. The 12-foot lanes require crews to make several passes in order to grind the whole width of each lane. The process is similar to mowing a lawn row after row, only this “lawn” is 72 feet wide and six miles long – in both directions.














Direct hit to Seattle and possible Web site slowdown

Seattle got a direct hit of winter weather just as the commute was getting going this morning. All routes into Seattle are congested. People are getting out of their vehicles on 520 and driving backwards to get off the freeway.

Those coming in from Federal Way may have had no idea things were this bad in the metro area - they just didn't see this weather when they left home. Vancouver is also getting its first taste of winter in the metro area.

Our Web site also hit a million page views by 7 a.m. this morning - this could cause some slowdowns for users. If this continues we will switch to a more basic site.

Most of Eastern Washington is compact snow and ice. Those taking this day off to go skiing - be ready for snow and ice.

Here's some tips if you have to go into the Seattle metro area today:

  • Do not drive against traffic on the freeway.
  • Do not abandon your vehicle because we can't clear the road if you aren't there to move your car.
  • Please check your entire route before you leave.
