| Emergency lane closures across the State Route 16 Tacoma Narrows Bridge to Gig Harbor for bridge joint repairs on April 27, 2026. |
Heads up State Route 16 commuters: more emergency repairs on the westbound 1950 Tacoma Narrows Bridge that takes travelers from Tacoma to Gig Harbor are on the horizon.
A quick history lesson first: the westbound bridge opened to travelers in 1950. It replaced the original Tacoma Narrows Bridge, forever known as “Galloping Gertie.” The 1950 westbound bridge has a few nicknames – one of which is Sturdy Gertie.
We want to level with you on the challenges our dear Sturdy Gertie is facing. We also want to share the steps we are taking to keep this landmark structure working for years to come.
The most pressing issue is the expansion joints. Those are the steel pieces on the bridge deck that make the “thuh-thunk” sound when you drive over them. There are small joints and large joints on the bridge. Like joints on a person, they work together to help the bridge move.
Three of the four large expansion joints near the towers have approached the end of their useable life. Up to now, we've been able to make temporary repairs and keep lane closures to a minimum. But temporary repairs can only last so long.

| A detailed description of the location, age and recent repairs of the large expansion joints on the westbound State Route 16 Tacoma Narrows Bridge to Gig Harbor. |
The graphic shows the locations of each expansion joint on the 1950 Tacoma Narrows Bridge. There are two by each tower, and each are labeled. There is a section in the Tacoma West Joint where temporary fixes will no longer work. This section is mostly under the two right lanes where the heaviest loads travel. We are at the point where a more extensive repair is needed to keep all lanes open until the aging joints can be replaced. The cost estimate for this extensive temporary repair is $140,000.
Here's the good, the bad and the not-so-surprising details on what's ahead:
The good
There is only one solution between temporary repairs and completely new joints– that's a partial joint replacement. This is a herculean effort, considering these parts aren't exactly available at the hardware store. We've been working with a local steel fabricator since August to create the partial joint and prepare it for installation.

The bad
Installing a new partial joint is a big job and requires two lanes across the bridge to close around the clock for two weeks. During the work the two right lanes of the Tacoma Narrows Bridge to Gig Harbor and the Jackson Avenue on-ramp to westbound State Route16 will close. This means two weeks of long afternoon commutes and delays for travelers. Many of us use the bridge daily and know what a pain this will be.
We expect to make these repairs in October and will share the start date for the work as soon as it's available.
When you drive across the bridge and pass the work zone while repairs are underway, chances are you may see little to no activity. That's because most of the repairs are happening underneath the bridge deck. After the work is finished, we also need time to see how the bridge responds before opening lanes for travel.
Daylight hours are required for this work. If we could do this kind of work at night, we would. This is precision work in a confined space while suspended high above the water. We do lots of other work at night, but this isn't one of them.
The not-so-surprising
This repair is one of many temporary fixes to help keep lanes open until the joints are replaced. It doesn't mean travelers won't see more emergency repairs in both this and other locations. Unfortunately, you can expect more lane closures across the bridge.
Whenever possible, we try to limit repairs during the weekday afternoon commute. But emergencies are just that, and we're not always able to wait until the evening or weekends to do the work.
In some cases, it's nearly impossible to identify where an expansion joint is damaged until it becomes apparent. There are areas of the bridge joints that are encased in concrete. Failures in those areas are often not visible until the driving surface begins to crack and deteriorate around them.
Why the joints keep breaking
The bridge is no spring chicken. As materials age, things begin to break. It faces wind, high traffic volumes and heavy loads. The metal and concrete driving surface expands and contracts in hot and cold weather.
We are now finding cracks and failures in the large steel joints with increasing frequency. Of the 10 emergency repairs since 2024, eight have occurred at the large joints on the bridge.
We weld new steel and add support structures where we can. But with each new temporary repair, the joints deteriorate more. We fix one spot, only to have another crack show up right next to it. It's like breaking a leg, getting a cast, and then breaking the same bone- just in a different spot.

Project to replace the joints coming
A project to replace the joints is in currently in design, with construction planned in 2027. We aren't building a new bridge – we're fixing Sturdy Gertie. Until we can get the work started, travelers need to be prepared for potentially more emergency lane closures and short-term repairs. We know you'll have lots of questions on what that construction will look like next year – we do too. We will share those details once we have them.
Replacing the bridge joints is one of several preservation projects we are tracking on the 76-year-old bridge over the next six years. We are prioritizing the work based on the emergent need and available preservation funding. The most recent increase in preservation funding in the state's transportation budget will help us keep Sturdy Gertie working as it should for years to come. Right now, just over $300 million is programmed through 2031 for preservation projects specific to the westbound bridge. Beyond next summer's bridge joint replacement work, additional preservation work includes painting the deck truss and towers of the westbound span in the next five years. This is a proactive step to preserve the steel. This proactive work means we save significant money in the future by not having to rehab and replace corroded elements of the bridge. The painting project would include some steel repair work, but it would not be to the point of major rehabilitation, if done soon. Painting the bridge would require full containment over The Narrows, which brings a high cost.
Bridge deck rehabilitation and cable dehumidification need to be done in the next 10 years. This work was recommended following a 2019 inspection.
We can't do all this work at the same time. Paying for each of these repair projects is dependent on funding in the state transportation budget, which is created and approved by the state legislature and signed by the governor.
Don't tolls pay for repairs on the westbound bridge?
No, the tolls you pay on the eastbound SR 16 Tacoma Narrows Bridge do not pay for maintenance on the westbound bridge. Tolls support the operations, maintenance, preservation and insurance costs for the eastbound bridge, which opened to travelers in 2007. The tolls are required until debt service, deferred sales tax, and loans provided by the state have been repaid. More details on Tacoma Narrows Bridge tolling can be found on the Washington State Transportation Commission's website.

Why can't you switch one of the bridges to handle both directions of travel?
The bridges do have this capability. However, it takes a long time to convert one bridge to accommodate both directions of travel. They are not set up like Seattle's express lanes. Switching directions of travel across the SR 16 Tacoma Narrows Bridge requires miles of traffic control barrels, cones and signs on both the Tacoma and Gig Harbor sides of the channel. It also requires reduced speeds in both directions. Putting this into place can take up to four hours, plus additional crew to implement. Trying to switch travel during heavy commute hours on this bridge would cause more backups, not less for travelers.
Is the bridge still safe to travel?
Yes. While we do have to close lanes and make emergency repairs, the bridge remains safe for travel in the open lanes.
Know before you go
If you travel from Tacoma to Gig Harbor, make a plan for emergency lane closures. Check the WSDOT app or the real-time travel map before heading across the bridge. Also, please sign up for our email updates. We work to only send these updates when necessary. We'll send out advance notification of significant work or an explanation of what's happening if we need to suddenly close lanes on the bridge.
When traveling, pay attention to messages on the electronic signs above the highway near the bridge. Have a full charge or tank of gas. Travel outside traditional afternoon commute hours whenever possible. There is also the possibility we'll open the HOV lane to all travelers, so please watch for announcements on the overhead electronic signs.
