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.

Most of the work will have minor traffic impacts. Here's what to expect:


  • Pier 2 Reaction frames construction – this work is underway this week in areas between Traffic Ave and BNSF on north side of SR 410. Day-time work that has potential to run into evenings – minor traffic impacts along Traffic Ave and onto right turn to Thompson Street with most of the slowdowns due to distraction because of tall crane in vicinity of traffic. Flaggers are on hand to assist pedestrians in the vicinity as well as creating rolling stops when the crane lifts and rotates 24” steel piles partially over Traffic Ave for few minutes at a time. Additional disruption may occur when the crane is disassembled and moved to south side later in the week. This effort would be undertaken when it causes the least impacts, probably after 8:00 PM at night
  • Pier 1 Reaction frames construction – this work would be performed later next and into the following week in areas between Traffic Ave and BNSF on south side of SR 410.

  • Ongoing west-bound off-ramp shoulder closure to build pond via the access road in the northwest clover of the west-bound SR 410 exit.
    Day time work later next week but most probably the week after – minor impacts to exiting traffic at times as equipment and trucks move in and out of the pond work zone. Traffic control measures along the shoulder of the exit ramp will be in place as well a movable impact attenuator to protect workers and traffic. Westbound SR 410 exiting traffic may encounter occasional slowdowns. There are no impacts predicted on north-bound Thompson, south- and north-bound Traffic Ave.

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

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

    LesleyP26 asked 2 months 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 2 months 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 2 months 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.

  • Now that a contractor has been selected, when is construction expected to begin?

    dacoobob asked 4 months ago

    Sorry just saw this! I am working out the kinks of this new website! Construction officially started on September 9th, 2019!
