Southbound I-5 Lane Closures Near Ship Canal Bridge
Two lanes of southbound Interstate 5 will close at the Ship Canal Bridge for the entire weekend. This closure is critical for replacing drains that date back to the 1960s. This work is a preliminary step for a larger pavement resurfacing project planned for next year.
The Ship Canal Bridge is a vital artery for north-south travel through Seattle. Its partial closure will likely create bottlenecks and extend travel times significantly. WSDOT advises drivers to plan ahead and allow extra time for their journeys.
Important Details
- Location: Southbound I-5 at the Ship Canal Bridge.
- Number of Lanes Closed: Two.
- Duration: All weekend.
- Purpose: Replacing 1960s-era drains in preparation for 2026 pavement resurfacing.
I-405 Southbound Work in Bothell and Kenmore
In addition to the I-5 closures, southbound Interstate 405 will also see lane reductions. This work will affect the stretch between Northeast 160th Street and Northeast 195th Street. These closures are part of a broader effort to maintain and improve the region's freeway system.
The I-405 corridor is crucial for eastside commuters. Drivers traveling through Bothell and Kenmore should anticipate delays. The combined impact of both I-5 and I-405 closures means a challenging weekend for regional traffic.
"We understand that these closures cause inconvenience, but this essential maintenance ensures the long-term safety and functionality of our roadways," a WSDOT spokesperson stated. "We urge everyone to check real-time traffic updates before heading out."
Impact on Local Traffic and Commuters
The simultaneous closure of lanes on both I-5 and I-405 presents a significant challenge for Seattle-area traffic. Drivers who typically use one of these major routes will need to find alternative paths. Local streets may experience increased congestion as drivers seek detours.
Public transportation options, such as King County Metro buses and Sound Transit light rail, could offer a viable alternative for some travelers. Checking bus schedules and light rail routes is advisable for those looking to avoid the freeway delays.
Background on Infrastructure Projects
WSDOT regularly undertakes maintenance and improvement projects to address aging infrastructure and accommodate growing traffic demands. These projects often involve replacing outdated components, resurfacing pavements, and improving safety features. The current work on I-5 and I-405 is part of these ongoing efforts to ensure the region's transportation network remains robust.
Planning Your Weekend Travel
Travelers should prepare for longer trip times. WSDOT recommends using navigation apps that provide real-time traffic updates. Leaving earlier or delaying non-essential travel could help mitigate the impact of the closures.
For those attending events or visiting attractions, factoring in extra travel time is crucial. The work is scheduled to continue through the weekend, with lanes expected to reopen by Monday morning's commute.
- Check WSDOT's official website for the latest updates.
- Utilize navigation apps like Google Maps or Waze for real-time traffic.
- Consider carpooling to reduce the number of vehicles on the road.
- Explore public transit options if your destination is accessible.
The department emphasizes that while rain is in the forecast, it will not deter the planned construction. Crews are equipped to work in various weather conditions to complete these critical infrastructure improvements.
