South 216th Street Bridge

South 216th Street Bridge

Construction crews will build a new, wider bridge that includes sidewalks, bike lanes, and a turn lane at South 216th Street. Building the new bridge includes demolishing the existing bridge and replacing it with the new one. People who walk and roll will have access across the bridge throughout construction.

The new bridge will have one lane in each direction, a center turn lane, five-foot-wide bike lanes and six-foot-wide sidewalks. The improvements will make it easier and safer for all people to get across I-5 in this location.

What can you expect (local access):

The bridge will be constructed in two stages.

  • Stage 1 (early 2022 to early 2023): During this stage there will be no impacts to the existing South 216th Street Bridge. We will construct the eastbound lanes of the new bridge next to the existing bridge.
  • Stage 2 (mid-2023 to late 2023): During this stage we will demolish the existing bridge and construct the westbound lanes of the new bridge. Eastbound lanes across the bridge will be closed for about six months. A detour route will direct drivers across I-5 at South 200th Street. The new bridge will be fully open by the end of 2023.

What can you expect (I-5):

In early 2022, drivers will see lanes shift and reduced lanes widths on I-5 between SR 516 and South 200th Street so crews can build the new South 216th Street bridge and the new ramps that will connect I-5 to the new SR 509 Expressway. In addition, drivers can expect nighttime lane closures in 2022 and 2023 when crews demolish the old bridge and set large concrete beams, called girders, for the new bridge. When these lane closures happen, all but one lane of either northbound or southbound I-5 will be closed during overnight hours, typically between 10 p.m. and 4 a.m. Drivers can also expect occasional single and double lane closures at night throughout construction.


Construction of the bridge will begin in early 2022 and end in mid-2023.
