Route 40: Construction updates - August 1, 2025

Route 40_fremont Trenching_8.1.2025

Crews dig a trench across Fremont Pl N for electrical conduit for improved pedestrian crossings and updated signals.

Dear Community Members,  

We are excited to share updates on the ongoing construction activities along the Route 40 Transit-Plus Multimodal Corridor Project. These enhancements are designed to improve transit reliability, pedestrian access, and overall street safety. 

New Drop-In Sessions 

Every Tuesday from 9 to 9:30 AM, residents and business owners have the opportunity to actively participate in our online open house for Route 40. These sessions provide an opportunity to connect directly with the project team, ask questions, share comments, or simply listen. They are a valuable way for the community to stay informed and engaged throughout the project. We encourage everyone to join us and be part of the conversation—your input is important and helps shape the project’s success! 

You can access the online meetings with the details below: https://us02web.zoom.us/j/83530373889 


What's happening in Fremont?

Our crews continue roadway, utility, and signal support activities in the Fremont neighborhood. Over the next few months, crews will complete conduit crossings, trenching, sidewalk removals, and some paving operations. Temporary impacts, such as lane restrictions, are expected, and signage will direct traffic accordingly. We appreciate your patience as crews work to improve the corridor.  

Construction activities include: 

  • Trenching and conduit installation  
  • Removal and replacement of sidewalks, roadway pavement, and curbs on Fremont Ave N and N 36th St at Phinney Ave N 
  • Upgraded/new bus zones near the Lenin statue and 1st Ave NW/N 36th St and N 35th St
  • Select sidewalk replacements from 1st Ave NW to Phinney Ave N 

Please note, construction is scheduled to happen throughout 2025. We anticipate a substantial portion of the work will be completed by the end of the 2025 but expect work to go into 2026. The schedule is dependent on weather, scheduling, and materials availability.

What's happening in Westlake?

Westlake Ave N & 9th Ave N – New Bus-Only Lane and Traffic Changes 

The map below shows upcoming traffic changes at the intersection of Westlake Avenue N and 9th Avenue N as part of the Route 40 Transit-Plus Multimodal Corridor Project. 

  • Area 1 (in red): This section of Westlake Ave N is a new bus-only lane. Buses will use this lane to make a protected left turn onto 9th Ave N from the far-right side of the roadway. 
  • Area 2 (in black with green dashed line): Crews will be adjusting signal timing and pavement markings in the intersection to accommodate the new bus movement. 

What to Expect 

  • People driving should watch for buses merging into and turning from the far-right lane. 
  • King County Metro operators will receive specific training to navigate this new lane configuration safely and efficiently. 
  • Access to nearby businesses, residences, and driveways will remain open throughout the transition.

Buses will use a special signal to perform this movement, so people driving may see buses perform turns when their signal is "red".


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 
  • Fremont: Bus lanes will be marked once nearby construction is completed.

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.
