Traffic Avenue/SR 410 Interchange

Construction is now underway, which means traffic will get worse in the short-term in order to get better in the long-term. Follow this page and perhaps select to receive weekly email updates from us to help you navigate through construction.

The City has deemed this transportation related project as essential and work will continue to move forward during the stay at home order issued by the governor.


September 28 - October 2

Here's what to expect for upcoming construction activities:

    • Construct Reinforced Slope – Crews will continue working on the eastbound SR 410 off ramp coming from SR 167 N/S to widen and build reinforced slope. This operation has effectively narrow the offramp to a single lane where commuters WILL NOT be able to use the shoulder at the Traffic Ave Intersection as they have previously.
    • Grade eastbound SR 410 offramp – As the reinforced slope comes to completion, the crew will begin final grading behind the temporary barrier on the eastbound SR 410 offramp. Minor traffic impacts are expected.
    • Underground power/signal work – Crews will continue working on underground conduits and signal work. Minimal traffic impacts if any are expected.
    • Fence/Handrail on approach slabs and beyond – Crews will install fence on the new approach slabs and beyond. No traffic impacts are expected.
    • Rolling slow down along Traffic Ave – Crew will be utilizing a rolling slow down to re-stripe Traffic Ave. near the Thompson intersection. This task may take a few hours early next week, and will be undertaken during off-peak hours.
    • Thompson Street from Traffic Ave turnoff closures – Increasingly, the crews will be utilizing closures around Traffic/Thompson turn pockets during parts of the work days. Considerable traffic impacts are expected however these closures are needed for paving and signal installation and tie-ins.

FUNDING PARTNERS

Please help us in thanking the many partners who came together to fund this project:

  • Transportation Improvement Board (TIB)
  • Puget Sound Regional Council – Surface Transportation Program (2 separate appropriations)
  • Sound Transit
  • Freight Mobility Strategic Investment Board
  • Port of Tacoma (2 separate appropriations)
  • Knutson Farms
  • State of Washington (2 separate appropriations)

THE SOLUTION

Reconfigure two intersections and add travel lanes plus multi-modal lanes across SR 410 to streamline the movement of vehicles, freight, pedestrians and bicycles safely and efficiently while encouraging ridership on Sound Transit and support for South Sound businesses.

Project budget is approximately $17 million.

Q&A

  • What's the estimated timeline for the new signals to go live? They have been up for a couple weeks now.

    moex asked 14 days ago

    The estimated timeline for the new signals to go live is mid-November 2020. Even though the new poles and lights of been installed, we still need to install and test the electrical wiring, conduit, and signal programming. The signals then need to pass inspection by WSDOT. We also need to remove the old signals, but that can't happen until the roadway alignment and widening improvements are complete. 

  • Would it be possible to open up the separated pedestrian/bike lane at the south side of the new bridge early, BEFORE the main bridge is opened to traffic? The ped path through the west intersection and across the old bridge is very sketchy, especially with the construction for the new bridge approach happening on the other side.

    dacoobob asked 3 months ago

    As soon as the separated path and sidewalk is completed on the east side of the bridge it will be open to use. 

  • 1- Traffic Avenue SB turning on to WB 410 is currently a tight fit for semi trucks. Has enough clearance been allowed for this to improve? There is a fair amount of trucks but you already know that. 2-The Main St turning left on EB 410 is a short turn lane over the river. Can you work with Puyallup to re-stripe the two way left turn into a longer queue for the left turn traffic? Since it is a bridge the two way left turn lane is useless. 3- Hopefully the project will enhance the lighting for the intersection of Traffic and Thompson for the pedestrians walking to the train station for the benefit of pedestrians and traffic. Thanks, Scott

    Sgthompson56 asked 7 months ago

    Hi Scott,

    1- Yes, this intersection is being reconstructed and will allow for truck turning movements. 

    2- The left turn lane to turn left to get on eastbound SR 410 will be extended as part of the project.

    3- New pedestrian lighting will be installed in both intersections on either side of the bridges and across the new bridge as part of the project.

  • What is the current estimated completion date? The contractor's website says Aug 2020, while the Sumner Connects site says Jan 2021.

    dacoobob asked 8 months ago

    The current estimated completion date is January 2021. 

  • Will there be a left turn arrow for those trying to access Hwy 167 North from Traffic Ave? There needs to be.

    Puyallup SDA Church asked 8 months ago

    Yes, there will be a new dedicated left turn lane and green/flashing yellow arrow signal for this turning movement. 

  • In regard to future parking, I suggest allowing commuter parking in the RPZ. I’d be willing to pay $50 per month for a sure spot. Each block could have a handful of slots, leaving the majority of slots to home owners. This no parking at all RPZ is just silly. Also, rentable scooters on the Puyallup and Sumner side would help SOME of us. Since traffic is terrible, it can take me 30 minutes to drive 3 miles, park, and catch my train. Simply intolerable!

    mayowan16 asked 10 months ago

    Thank you for your suggestion.

  • Will traffic from Puyallup still have to make a left turn in order to access HWY 167 north?

    tvgjheino asked 11 months ago

    Yes, traffic from Puyallup will still have to make a left turn in order to access HWY 167 north. There will be a new dedicated left turn lane and green/flashing yellow arrow signal for this turning movement. 

  • The arrows for "To Tacoma/Seattle" and "To Bonney Lake" seem to be in the wrong place.

    LesleyP26 asked about 1 year ago

    The City will inspect the detour signs and correct them if they have been installed incorrectly. Thank you for the heads up!

  • Where will sound transit commuters park once the project is complete, since the City of Sumner is no longer allowing them to park on streets near the station?

    lacey07 asked about 1 year ago

    Yes, we realize it's getting really, really tough and trying to balance commuter parking (i.e. down Academy Street) with residents needing access during the day and businesses needing parking is no picnic. We're talking to Sound Transit to try to find some other options for commuters. Any suggestions? 

  • We need a Photo-enforced traffic camera on these intersections... trucks are running red lights at full speed... We need an ordinance that prohibits "Intersection blocking"... cars are crowding the intersections and stopping traffic from moving...

    jak_raft asked about 1 year ago

    With this project there will be a new layout and traffic signal design at each of the intersections at either end of the Traffic Avenue Bridge. These instances of "intersection blocking" should be solved once the project is complete.
