Overnight Construction 

Please note, you can expect to experience and hear construction activities overnight as part of our work to upgrade the watermain.

What to Expect    

  • You may hear loud humming and grinding, diesel engine exhaust, and workers' voices. You may also hear and feel low pitch vibrations 
  • Noise, dust, vibration, and large vehicle traffic 
  • Increased lighting around the construction area 
  • Temporary parking and lane restrictions in select areas 

Water Main Infrastructure Upgrades

The Seattle Department of Transportation (SDOT) is working with Seattle Public Utilities (SPU) to replace a 100-year-old waterline under Fremont Ave N between N 34th St and N 35th St and on Dayton Ave N and N 36th St. Completing the water main upgrades and the street upgrades at the same time will help reduce impacts to the community by coordinating major construction projects. This approach helps minimize travel disruptions, lower construction costs, and shorten the overall construction timeline compared to completing the projects separately.

When complete, the watermain upgrades are expected to:

  • Improve capacity to deliver drinking water in your neighborhood
  • Improve water system flow and pressure
  • Ensure water service reliability and reduce disruptions

Our team is actively providing affected business owners and residents with the most up-to-date information. You can learn how best to prepare for water main work by visiting  SPU's webpage for tips on preparing for a water outage. If you have any specific questions or require further assistance, don’t hesitate to reach out to us at Route40@seattle.gov.

WSDOT Revive I-5 and Ship Canal Bridge Preservation Project  

As part of WSDOT’s effort to preserve and repair I-5, they will be fully closing northbound I-5 from I-90 interchange to Northeast 45th Street between July 18- 21.   

This weekend’s critical watermain infrastructure work is being thoughtfully planned to minimize disruptions during WSDOT’s closure. This includes scheduling work during off-peak hours to reduce traffic impacts. Our goal is to keep neighborhood disruptions to a minimum while completing these essential infrastructure upgrades in Fremont.  

We encourage residents and commuters to plan ahead and, if possible, consider alternative transportation options to avoid delays.


What does construction look like throughout the corridor? 

North Seattle (around Holman Rd N) 

Crews successfully installed new street markings and signage along Holman Rd N. Please take extra caution as traffic will slightly shift to accommodate the new bus-only lanes. 

Fremont 

In early July, sidewalk demolition and utility upgrades—including waterline work—has been underway- continues. These essential improvements will help ensure reliable water services and safer pedestrian pathways.  

Signaling and intersection enhancements will begin, including signal and crosswalk upgrades to improve safety for pedestrians and drivers. This work will also include some excavation and infrastructure upgrades. 

Westlake 

In the Westlake area, active construction will focus on installing new traffic signals, improving signage, and upgrading street lighting to enhance safety and traffic flow. Crews will also perform sidewalk repairs and support utility upgrades. Some lane closures and temporary traffic controls might be in place during these activities.  


New Bus-Only-Lanes!

We have begun installing new bus-only lanes in five key locations along the route. These transit enhancements are designed to improve transit reliability and travel time for Route 40 riders while maintaining access for local businesses and residents. Here are the latest updates: 

  • Ballard: Striping and bus-only lane markings has been completed.
  • Holman Rd N: Striping and bus-only lane markings are completed in this north Seattle neighborhood. The new design plans for the bus-only lanes between 3rd and 104th reflect the transit improvements we’ve installed. The center turn lane was removed to accommodate these transit improvements.
  • Westlake: Striping and bus-only lane markings have begun this week and will continue into this week. 
  • Traffic signals on Westlake will be installed in the coming weeks.
  • Fremont: Bus lanes will be marked once nearby construction is completed.

Bus Only Lanes

The Route 40 bus continues down the new bus only lane on NW Market St after dropping off passengers in Ballard.


Route 40 Ridership is on the Rise

Route 40 has over 8,500 average weekday daily boardings (Fall 2024) - an 11% increase from Fall 2023. It is the fifth (5th) highest ridership route in the Metro network.

Project Benefits

In addition to the 5-10% transit travel time savings, 14-17% in Ballard to Downtown, the Route 40 project will maintain and modernize vital infrastructure

What you can expect during construction

  • Temporary lane reductions
  • Temporary driveway closures
  • Temporary bus stop closures
  • Temporary parking restrictions
  • Temporary sidewalk detours
  • Temporary storage of construction supplies in the street  
  • Temporary noise, dust and vibrations
  • Bus stop relocations
  • Drainage work: This involves digging trenches to help manage water flow
  • Signal pole foundation excavation: This work involves digging for the pole foundations prior to when we order custom signal poles which takes a while to build and to make sure we know there are no underground obstructions  
  • Trenching for conduit: This involves digging trenches to lay down pipes or cables underground
  • Sidewalk curb bulb out: This involves making the curbs stick outward for safety or accessibility
  • Mill and fill overlay: This is when the top layer of the road gets removed and replaced with new asphalt

The construction timeline is always subject to change depending on weather conditions and materials availability. We are committed to keeping you informed and maintaining open communication throughout the remainder of this project.To learn more about the project and designs, visit our online open house.
