  • Jan. 17 #Realign 99 update: Rolling into Thursday

    Update 7:15 p.m.

    This evening we saw roughly average travel times on Seattle’s highways. We appreciate how drivers and transit riders are adjusting their travel times to ensure they arrive where they need to be on time. These adjustments are resulting in more bus riders earlier and fuller buses on popular routes.

    This morning 933 people commuted on the West Seattle Water Taxi, compared to 320 riders in 2018. The Water Taxi continues to have capacity for riders, and there also is room on free shuttles, Ride2 shuttles and at the Pier 2 parking lot in West Seattle. See this overview of Water Taxi services.

    On the construction front, crews poured a stretch of concrete at the tunnel’s north end that will form part of the two southbound SR 99 lanes heading into the tunnel. You can see the pour on our SR 99: Tunnel Connections North construction camera. Crews covered the concrete to protect it from rain, and now it sits to cure. Below is a close-up of the crew at work:

    Another day, another decent morning commute. We saw a few incidents this morning, but nothing major. The most noteworthy event this morning didn’t even occur on the highway – a brief outage that prevented access to parts of our website. The problem was resolved before 7 a.m. and everything is back online.
     
    Rain moved in overnight, bringing an end to the dry spell that aided crews for the first several days of the closure. Work continues on highway barriers. Crews have completed quite a bit of lane striping on newly built sections of roadway. They’re also making progress on the new intersection at First Avenue South and South Dearborn Street.

  • Jan. 16 #Realign99 update: More of the same

    Update: 7:15 p.m.
    Today we enjoyed what may be the last day of dry weather this week. One critical component of work occurring at the south portal during the closure is completing the SR 99 northbound off-ramp that will take drivers to Alaskan Way or South Dearborn Street. This ramp was bisected by the highway before we closed it on Friday; now crews are working on both sides of the structure. The photo shows crews placing soil atop a membrane that sits atop geofoam fill. A concrete slab will be poured atop this soil soon.

    On the commute, King County’s West Seattle Water Taxi ridership continues to be high: this morning’s commute was up nearly 200 percent compared to this day last year. There is still capacity on the boats, in the Pier 2 parking lot, and on the shuttles taking commuters down to the West Seattle terminal, so if you are a West Seattle commuter, consider trying your friendly local water taxi.
     
     
    Posted: 12:18 p.m.
     
    Clouds are finally rolling in after several days of sun, but the third weekday morning commute of #Realign99 remained relatively clear. Most roadways in the region had travel times near or below three-month averages, and below travel times we saw last Wednesday, before the closure began. People are still shifting their commute, so we can still see an additional 10 to 20 minutes of delay, depending on the time of day. 
     
    We’ve seen small but consistent travel time increases on northbound I-405 to Bellevue and northbound I-5 from I-405 to Seattle. Northbound SR 167 from Auburn to Renton and northbound I-5 from Federal way to I-405 saw a small increase. We are seeing some longer-than-normal backups on northbound I-5 to downtown exits, particularly Mercer Street, where backups have extended through the convention center tunnel.
     
    As we saw on Monday and Tuesday, most delays have occurred earlier in the commute. With rain in the forecast and the potential for folks to fall back into their old routines, we’re asking travelers to stay the course. Let’s all continue to do our part to keep the system flowing smoothly. 
     
    Crews building the tunnel connections continue to benefit from the good weather. They’re building barriers on the northbound on-ramp from South Royal Brougham Way into the tunnel, and continuing work on the new intersection at First Avenue South and South Dearborn Street. At the north portal, crews are placing rebar in preparation for concrete pours that are scheduled to occur early next week.

  • Jan. 15 #Realign99 update: South end commuters feeling the squeeze

    Update: 6:45 p.m.

    The Puget Sound region saw a pretty good evening commute tonight, aided by dry weather and quick work by crews clearing traffic incidents. WSDOT, SDOT and King County Metro are monitoring transit travel times and looking for places where traffic signal timing or other changes could be made to keep buses moving.

    West Seattle Water Taxi demand remains strong and Ride2 West Seattle shuttles are in service. There's also more frequent service on free shuttle routes 773 and 775. King County Metro deployed standby buses on 51 trips today and carried an estimated 1,700 riders on those buses.

    Keep up the good work and enjoy the good weather while we can. The forecast is looking less summer-in-January for the end of the week. 


    Posted at 12:03 PM

    Thanks to another dry morning, crews building connections to the new tunnel continue to make good progress. They expect to finish removing geofoam from the new South Royal Brougham Way northbound on-ramp later today. Following that, they’ll focus their efforts on installing highway barriers. Several concrete pours will occur in the coming days at both the north and south portals. Striping is also underway on new sections of roadway. Overall, work is proceeding as planned.

    The morning commute was slightly less favorable than the weather. After a smooth commute on Monday, Tuesday got off to a rough start. Several incidents slowed traffic during the morning commute, which again started earlier than usual. South end commuters had slower travels than most. Travel times on northbound I-405 and northbound SR 167 were approximately 10 minutes slower than usual.

    Still, many other corridors were flowing smoothly, and in some cases better than normal. Travel times on southbound I-5 between Everett and Seattle were faster than usual. Overall, travel times were close to normal on many routes. 

    With increased congestion on the West Seattle Bridge, many West Seattleites are taking advantage of increased Water Taxi service. Yesterday, West Seattle Water Taxi ridership was up 269 percent from the same day last year, with some capacity remaining on boats.

  • Jan. 14 #Realign99 update: The first commute

    Update: 7 p.m. Monday, Jan. 14

    Aided by dry weather, crews are hard at work on the ramps at both ends of the tunnel. The photo below shows crews removing geofoam blocks from the tunnel’s previously buried northbound on-ramp. Just three days ago, northbound SR 99 went over the top of this ramp.

    As of 6:30 p.m. tonight, the first #Realign99 evening commute was going reasonably well. Highways and Seattle streets saw some backups and heavy traffic starting a little earlier than normal. King County Metro buses ran 47 extra stand-by coach trips combined between the morning and evening commutes to handle expected increased ridership. SDOT added new signage on the West Seattle Bridge to emphasize the bus-only lane, and implemented longer peak-commute signal timing on key thoroughfares.

    One day in the books! Mondays tend to see lower traffic volumes generally, so we will learn more as the week progresses. But to those commuters and employers who made plans and altered your commutes, thank you, and keep it up.
     

    Original post: Monday morning, 11:30 a.m.

    Over the weekend crews completed all scheduled work, which included removing one small section of the ramp that used to carry northbound SR 99 up onto the Alaskan Way Viaduct near the new tunnel’s south portal. Crews are scheduled to begin paving the new S. Dearborn St. later this week.

    This morning was the first #Realign99 commute since the Alaskan Way Viaduct closed. Overall, highway, local streets and transit operations were similar to average weekday conditions. Morning commute times started earlier than normal, and a few bus routes experienced increased travel time. The Water Taxi from West Seattle saw significantly increased ridership, but capacity was not filled.

    What does this mean? It looks like all those plans you made are working!

  • Jan. 13 #Realign99 update: Preparing for Monday's commute

    The first weekend of the #Realign99 closure is coming to a close. Traffic patterns were typical for a weekend, but the biggest test is yet to come. Focus now shifts to Monday's commute, the first since the Alaskan Way Viaduct permanently closed on Friday night.
     
    We've spent months asking people to plan ahead for this major traffic event. It's not too late to visit our closure page for a list of resources to help you navigate the longest planned highway closure the region has ever seen. We're expecting the effects of the viaduct closure to extend to routes throughout the region, so please plan accordingly. Allow extra time for your trip, and be sure to pack plenty of patience. 
     
    In addition to highway construction at each of the tunnel portals, crews spent the weekend demolishing a small portion of the viaduct near the stadiums. Until Friday, this section of roadway carried northbound SR 99 from the construction detour up onto the viaduct. Removing this part of the ramp makes space for construction of the new intersection at South Dearborn Street, at the new tunnel's south portal.
     
    Viaduct safety
    The Alaskan Way Viaduct is now part of a construction zone. Members of the public are prohibited from entering the structure. Security is on site at each of the access points and will contact police if people trespass. The public will have access to the viaduct on Feb. 2-3 as part of our Step Forward celebration. At that time, we will have appropriate barriers in place along the viaduct for public safety. We are encouraging everyone to sign up at 99stepforward.com for the events to guarantee access and plan their day.      
     
    Check here for daily updates on traffic and construction progress throughout the #Realign99 closure. Resources for planning your commute are available on our closure page. Track construction on our time-lapse cameras, and be sure to follow us on Twitter for updates, photos and videos.

  • Jan. 12 #Realign99 update: Viaduct demolition this weekend (just a small section)

    Crews are making quick work demolishing a small portion of the viaduct near the stadiums. Until yesterday, this section of roadway carried northbound SR 99 from the construction detour up onto the viaduct. Removing this section of the northbound ramp makes way for construction of the new intersection at South Dearborn Street, at the new tunnel's south portal.

  • Jan. 11 #Realign99 update: Closing time for the Alaskan Way Viaduct

    And that's a wrap. After more than six decades of service, the Alaskan Way Viaduct is permanently closed to traffic.
     
    Crews began closing the Columbia Street on-ramp at approximately 9:45 p.m. Friday. As midnight approached, the final cars had exited the double-deck structure, setting the stage for the approximately three-week #Realign99 closure.
     
    During the closure, crews will build the final connections to the new SR 99 tunnel. Viaduct demolition will begin after the tunnel opens in early February. A small portion of the viaduct near the stadiums will be demolished this weekend to make way for the new intersection at South Dearborn Street, at the new tunnel's south portal.
