Here's what is included in this month's email update: 

• Construction updates 
• Updates on what we’ve been working on and construction progress 
• What’s coming up next month 
• Resources and contact information 

Earlier this month, our crews finished the last concrete work on the project. Finishing concrete installation represents a significant milestone as we move closer to completion on a fully rebuilt corridor through Seattle. All new concrete will undergo inspection this spring and summer. Improvements will take place where necessary. 

In total, this project has poured more than 67,973 square yards of concrete roadway and panels as well as 14,234 square yards of new concrete sidewalks. This new infrastructure will enhance the safety, comfort and efficiency for travelers in downtown, First Hill, Capitol Hill and Madison Valley.  

New Signal Work 

Green shoots aren’t the only things springing up on the Madison St. corridor. New signals haven been going up at different intersections along the future RapidRide G – Madison St. route. You may have already seen new signal mast arms along at various locations. As of the end of March, all new signal structures are now in place with only one remaining – at the corner of Madison St and 2nd Ave. The next phase of work will connect new signals to the traffic and electrical grid. 

In April, we’ll begin work on the installation of a new signal at the intersection of Spring St. and 7th Ave. While we install the new signal hardware, there will be temporary traffic changes through the intersection.

Bus Islands 

We continue to make great construction progress, including building the new center bus stations, or bus islands. Once the RapidRide G Line project is complete, there will be new red bus lanes from 1st Ave to 18th Ave and four new bus islands. These islands are located at 8th, Terry, Boylston, and 12th Avenues. Bus shelter frames have already been installed on the bus islands located at 8th, Terry, and Boylston Avenues. The shelter frame at 12th Avenue will be installed later in April. 

Clean up and restoration at 9th Ave and Madison St 

Construction on the future comfort station in Madison Valley continues. We finished repaving the roadway in this area and have started to build the platform and foundation for the structure that will serve our operators. Construction will continue into the spring.

 

Detours and Closures 

Madison Street will be reduced to one lane in downtown 

In mid-March, we started conducting trenching and utility conduit work in the area of 2nd Ave and Madison St. During this work, Madison St. was reduced to one lane. This lane reduction remains in place.  

15th Ave has reopened and is now southbound-only    

15th Ave, north of E Madison St., has reopened to vehicle traffic. However, this section of 15th Ave is open to southbound traffic only. This segment of 15th Ave will remain southbound-only permanently.   

Access to E Madison St from southbound 28th Ave is back open  

Vehicle access connecting to E Madison St. or Martin Luther King Jr Way from southbound 28th Ave has reopened. Our crews have completed most of the sidewalk and utility work in this area and no longer require a roadway closure. It is possible that there will be short-term closures to southbound 28th Ave when our crews revisit the area to complete additional sidewalk and driveway work.  

What we’ve been working on 

• Formed and poured 511 square yards of concrete roadway panels. Be advised the paving is largely complete and we are wrapping smaller areas at intersections or in front of driveway with special access considerations.
• Formed and poured 498 feet of concrete curb.
• Formed and poured 953 square yards of concrete sidewalk.
• Formed and poured 168 square yards of concrete driveways.
• Installed 46 new signal heads.
• Installed 27 signal and light pole foundations.
• Trenched and installed 7,992 feet of signal and lighting conduit, including 64 new underground electrical vaults and junction boxes.

The RapidRide G – Madison St project surpassed the 80% completion mark earlier this year! Click here to learn more. 

King County Metro bus stop closures & relocations 

As construction continues, we will need to temporarily reroute buses or close and relocate bus stops. These detours and closures can change frequently. Please visit King County Metro's Transit Alert page for the most accurate information and sign up for Metro Transit Alerts. Metro Alerts are the best way to stay up to date on bus reroutes and impacts to bus stops.
