Traffic Alert: Trans-Siberian Orchestra & Seattle Marathon will impact traffic this weekend

Two traffic alerts for today and tomorrow – Trans-Siberian Orchestra is at Key Arena today, Saturday, for performances at 4pm and 8pm. The city estimates 10,000 people will attend each of the shows (20,000 total), so expect traffic around Key Arena this afternoon and evening.

The bigger impact will likely be from the Seattle Marathon, which is tomorrow, Sunday, November 29th. The organizers cite the Seattle Marathon as the “largest combination marathon/half marathon in the Northwest and one of the top ten largest in the US” – what does that mean? 15,000 participants + thousands of spectators, and road closures around the Seattle Center, where the race starts and finishes.

The race map with street closures is below. For some reason, the Seattle Marathon organizers have once again decided to produce a West-oriented map, instead of the standard North-oriented view. So, it may look a bit odd, but note that 5th Ave near the Seattle Center will be closed 5:30am-9am, and one side of Mercer will be closed 8:45am-4pm.

And, just to make things a bit more complicated, traffic-wise, the Seahawks are playing the Pittsburgh Steelers at CenturyLink tomorrow (Sunday), with kickoff at 1:25pm.

President Obama to attend Murray fundraiser at Westin this Friday

Westin Hotel mapPresident Obama will be visiting Seattle this Friday for a fundraiser at the Westin. The event is to raise funds for Senator Patty Murray’s re-election campaign, but few details have been released about the event or streets that will be closed.

Per SDOT, I5 and city streets will be impacted by the visit. Expect some traffic impacts around Queen Anne due to the proximity of the Westin and the ripple effect on Mercer.

Two month closure of one block of Roy St starts Tuesday

As part of the Mercer Corridor Project, SDOT will be fully closing Roy Street between 4th Ave N and 5th Ave N for 6-8 weeks. The closure begins tomorrow, Tuesday, September 8th. Vehicle traffic will be detoured to Mercer, so expect increased traffic on Mercer St during the closure.

Here are the details from SDOT:

Roy St closure fall 2015

SDOT advises travelers of a full street closure on Roy Street between 4th Avenue N and 5th Avenue N for six to eight weeks beginning Tuesday, Sept. 8. This closure will accommodate installation of a large storm water detention pipe beneath Roy Street in September and October. This will help manage storm water flows and reduce the risk of sewer overflows into Lake Union during a heavy rain. It will provide storm water detention for the area, including the North Portal and surface street improvements for the SR 99 Tunnel Project. Travelers through the area can expect the following:

• Beginning Tuesday, September 8, Roy Street will be fully closed between 4th Avenue N and 5th Avenue N and remain closed for six to eight weeks.

• Local access will be maintained to the alley on the south side of Roy Street between 4th Avenue N and 5th Avenue N via eastbound Roy Street. The alley will be southbound only during this closure.

• Vehicles and cyclists traveling on Roy Street will be detoured south to Mercer Street between 4th Avenue N and 5th Avenue N. Please obey all closure and detour signage.

• Street parking will be restricted on this block while work is completed.

• Pedestrian access will be maintained on the south sidewalk along Roy Street.

Traffic Alert: Bumbershoot starts Saturday and runs through Monday

BumbershootUPDATE: Bumbershoot starts tomorrow, not today (thanks, migraine).

A late heads up, but if you aren’t aware, Bumbershoot is this weekend at the Seattle Center. The festival starts tomorrow, Saturday, September 5th, and runs through Monday, and 50,000 people are expected each day. You can find out about all the Bumbershoot events and acts here.

Here’s SDOT’s notice about traffic impacts:

The Seattle Department of Transportation (SDOT) advises travelers to be aware that Bumbershoot runs this weekend through Labor Day. The annual art, film and music festival takes place at the Seattle Center beginning Saturday, Sept. 5 until Monday, Sept. 7 at 1:30 p.m. tomidnight daily. About 50,000 people are expected to attend each day. Please travel safely and plan ahead for possible delays.

Expect an increase in traffic around Queen Anne this weekend, which is typical for the summer. Those who are frustrated can take solace in Labor Day weekend signalling the end of big summer event traffic (although there will always be traffic…).

Aurora closure this weekend between Battery St Tunnel and Valley St, plus Aurora Bridge lane closures

Heads up for weekend travel plans – Aurora/SR99 will be closed between Valley St and the Battery St tunnel. Here are the details from WSDOT – expect extra traffic on Queen Anne due to detours:

Aurora closure August 2015Starting Friday night, contractor crews working for the Washington State Department of Transportation will close SR 99/Aurora Avenue North between the south end of the Battery Street Tunnel and Valley Street. This closure will give contractor crews the space they need to shift traffic onto roughly 750 feet of new roadway in time for Monday morning’s commute.

The new roadway is actually a bridge. Once the traffic shift is complete, Atkinson Construction crews will work underneath the bridge to complete construction on the northbound ramps and roadways that will connect to the SR 99 tunnel.

Drivers should plan and prepare for additional congestion on nearby streets during this time by using WSDOT’s travel tools or SDOT’s traveler’s information web page.

Closure details:

  • Both directions of SR 99 between the south end of the Battery Street Tunnel and Valley Street will close from Friday night, Aug. 21, to Monday morning, Aug. 24.
    • Southbound lanes close at 10 p.m.
    • Northbound lanes close two hours after the Mariners game, to help fans get home from the game.
  • All lanes reopen by 5 a.m. Monday, Aug. 24, in time for the morning commute

Additional work on the Aurora Bridge:

  • On Saturday, Aug. 22, WSDOT bridge crews will close up to two right lanes of northbound SR 99 across the Aurora Bridge for maintenance work from 5 a.m. to 5 p.m.  
  • On Sunday, Aug. 23, WSDOT Bridge crews will close two southbound lanes of the Aurora Bridge from 5 a.m. to 5 p.m. to continue maintenance work on the other side of the bridge.

Changes to Harrison Street at SR 99 starting Aug. 24

  • Drivers will no longer be able to enter northbound SR 99 via westbound Harrison Street after SR 99 reopens Monday, Aug. 24. This closure is for additional construction in the area. Access to northbound SR 99 from Thomas and John streets will remain open.
  • Northbound drivers on SR 99 will be able to exit at Harrison Street as they do today.

Here’s a video from WSDOT that shows the plans and what to expect in the future:

Seafair Pirate Run and Torchlight Parade kick off at Seattle Center on Saturday

Seafair Torchlight Parade routeIt’s that time, Seafair activities are starting to pick up steam. Tomorrow, Saturday, July 25th brings the annual Seafair Torchlight Parade  and the Seafair Pirate Run to the streets of Seattle. And, it all starts at Seattle Center, so plan ahead for any traffic and parking issues it may bring along with it.

While up to 300,000 spectators are still grabbing spots to view the parade, the Seafair Pirate Run will be starting and ending at Seattle Center. The 5K/8K run starts at 6:30pm at the Seattle Center. Roughly 4,500 runners will head down the Viaduct to Royal Brougham and back to the Seattle Center to finish just as the parade gets going.

The parade starts at 7:30pm and the route takes it from the Seattle Center down 4th Ave to Pioneer Square. The main viewing area is at Westlake, but parade goers will line the route both north and south of Westlake. Pre-parade staging will occur near the Seattle Center, so expect road closures. Per SDOT:

“The northbound lanes of the Alaskan Way Viaduct will be closed from 5:30 p.m. to approximately 7:45 p.m. for the 5 k and 8 K Seafair Torchlight Run races. At approximately 6 p.m. Fourth Avenue will close from Broad Street to South Washington Street, complicating traffic circulation in the downtown area. Fourth will reopen around 10:30 p.m. and routes out of downtown will be congested as the crowds leave the event.”

King County Metrol service will be rerouted and delayed by the events from 3pm to 10:45pm – specifically around the Seattle Center, downtown Seattle, Alaskan Way Viaduct and adjacent areas.
