The Washington State Department of Transportation has scheduled a two-week partial replacement of worn expansion joints on the westbound State Route 16 Tacoma Narrows Bridge for October, with the two right lanes closed through the work, spokeswoman April Leigh confirmed on October 1.
Drivers traveling from Tacoma to Gig Harbor and on to the Kitsap Peninsula should plan extra time, combine crossings, or shift discretionary trips outside the work window, because the closures will run around the clock once they begin.

- What: Partial replacement of worn expansion joints on the westbound span.
- When: Two full weeks in October 2026, with the exact start date still to be announced.
- Where: Westbound State Route 16 across the Tacoma Narrows Bridge, Tacoma to Gig Harbor.
- Closure: The two right lanes stay closed day and night through the work period.
- Status: Confirmed by WSDOT in its project briefing and in an October 1 local report.
October Work Will Close Two Westbound Lanes for Two Weeks
WSDOT explains in its project briefing that three of the four large expansion joints near the bridge towers have reached the end of their usable life, and that temporary fixes can no longer hold the section under the two right lanes near the Tacoma side. The agency will cut out and replace part of the failing joint, weld new steel, and pour fresh concrete during a single extended work period.
The repair is precision work performed underneath the bridge deck, where crews labor in harnesses suspended high above the water, Leigh told KIRO 7 in its October 1 report. Because the bridge moves, crews cannot cover the open joint with a steel plate or reopen lanes between shifts, so the two right lanes will remain shut around the clock for the full two weeks.
WSDOT has not yet published the exact closure dates, so travelers cannot circle a start day on the calendar. The practical effect is a month-long caution zone: any westbound crossing in October could fall inside the closure window, and drivers should check agency alerts before every trip until the agency names its dates.
Why the 1950 Span Needs Surgery Now
The westbound bridge opened to travelers in 1950 and carries the nickname Sturdy Gertie, a nod to the original 1940 span whose collapse made engineering history. Its four massive expansion joints sit at either end of the crossing near the towers, flexing as traffic and weather move the 76-year-old structure through each day.
Those joints have needed eight major emergency repairs since 2024, and Leigh says short-term spot fixes are becoming increasingly common without lasting. The fourth large joint, closest to Gig Harbor, was replaced about a decade ago, leaving the three remaining originals as the weak point. WSDOT has worked with a local steel fabricator since August to build the partial joint, since replacement parts for a bridge of this age are not available off the shelf.
What to Expect During the Daytime Closures
Drivers should expect significant delays on westbound State Route 16 before and across the bridge, with backups likely to stretch back toward Tacoma during peak travel periods. The crossing is the only direct highway link between Tacoma and Gig Harbor, so squeezed lanes cannot be relieved by a simple signed detour around the work zone.
Because the lanes cannot reopen overnight, off-peak daytime crossings will meet the same restriction as rush hour trips through the two weeks. Travelers who cross daily should treat the entire work period as reduced capacity and build a generous buffer into every westbound trip, including weekend crossings that might otherwise feel safe.
Alternate Plans Around the Narrows
The most reliable strategy for flexible trips is calendar control: move discretionary Gig Harbor and peninsula visits to before the closure window opens or after it closes. Shoppers, diners, and day visitors with open schedules lose nothing by waiting for full capacity to return before crossing.
Committed travelers should consolidate errands into fewer crossings and watch WSDOT traffic alerts for the exact dates, which the agency still needs to publish. Road trippers towing through the corridor can match overnight stops to the delay outlook with our RV Parks Near Tacoma, WA guide before locking in a route.
Peninsula Trips Are Still Possible With Extra Time
The closure narrows the road but does not sever it, so Kitsap Peninsula and Olympic Peninsula itineraries can proceed with adjusted schedules. Ferry connections, lodging check-in times, and tour departures on the far side deserve wider margins than usual during the work window.
Travelers heading farther west should also confirm the rest of their route, since mountain and park roads run on their own seasonal repair calendars. The bridge delay is only one variable in a long driving day, and a calm plan absorbs it better than a tight chain of timed reservations.
| If you… | What to do |
|---|---|
| Commute from Tacoma to Gig Harbor | Add a large buffer to every October westbound trip until WSDOT names exact dates. |
| Plan a flexible day visit | Schedule it before or after the two-week October work window. |
| Head to the Kitsap or Olympic Peninsula | Widen margins for ferries, check-ins, and tours on travel days. |
| Tow an RV through the corridor | Set overnight stops that tolerate slow crossings and monitor agency alerts. |
The October date announcement is the first gate. Recheck WSDOT alerts before booking any October westbound crossing, since the two-week window is not yet dated.
The work window itself is the crunch period. Cross early in the month or after work ends for discretionary trips, and pad committed crossings heavily.
Full capacity restoration is the all-clear. Resume normal timing only after WSDOT confirms the new joint is in service and all lanes are open.
When exactly will the Tacoma Narrows Bridge lanes close?
WSDOT has scheduled the work for October 2026 but has not published exact start and end dates. Check agency traffic alerts before each October trip until the dates are named.
Which direction is affected by the October work?
The closures affect the westbound span carrying State Route 16 from Tacoma to Gig Harbor. The agency has described this work as a westbound joint replacement.
Will the closed lanes reopen at night?
No. WSDOT says crews cannot plate over the open joint or reopen lanes between shifts because the bridge moves, so the two right lanes stay closed around the clock.
Where can drivers check the latest status?
Watch WSDOT traffic alerts and the agency project briefing for the exact dates and daily conditions. Local outlets including KIRO 7 are tracking the October schedule as details emerge.
