Drivers who cross the Tacoma Narrows Bridge daily received a modest boost of good news on Tuesday. The Washington State Department of Transportation (WSDOT) announced that crews have installed a new partial expansion joint on the westbound span of the 76‑year‑old bridge.
Why the work matters
The bridge’s four massive expansion joints, located at each end where the towers rise, have been a chronic source of trouble. Since 2024, eight major emergency repairs have been required at these joints, causing frequent lane closures and frustrating delays for commuters on State Route 16.
WSDOT explained that the most deteriorated section of the original joint was removed yesterday, and the replacement segment is now in place. While this addresses the most critical weakness, the agency emphasized that the overall rehabilitation project is far from finished.
What commuters should expect
“Plan for long commutes or telework, carpool, and combine trips from Tacoma to Gig Harbor until we’re done,” WSDOT advised in its release. The department also pointed drivers to its real‑time traffic map, which provides up‑to‑date travel times and lane‑closure information.
At this stage, officials have not provided a definitive timeline for the remaining work. The bridge’s age and the complexity of the joint system mean that additional phases—such as full joint replacement and structural reinforcement—are likely to extend into the coming months.
Community impact
For families and workers who rely on the bridge to connect Tacoma with Gig Harbor and the broader Puget Sound region, the partial joint installation is a welcome sign that the long‑standing infrastructure issues are being addressed. The bridge is a vital artery for commerce, emergency services, and daily travel, and keeping it safe aligns with the community’s values of responsible stewardship and reliable transportation.
Local businesses on both sides of the water have expressed relief that the most urgent repair has been completed, hoping that the remaining work will proceed without further unexpected closures.
Looking ahead
WSDOT will continue to monitor the new joint’s performance and will release updates as additional phases begin. Residents are encouraged to stay informed through the department’s website and to consider flexible commuting options whenever possible.
By tackling the bridge’s most vulnerable component, the agency is taking a concrete step toward preserving a historic landmark that has served Washington motorists for three‑quarters of a century.
