The I-5 Express Lanes will be closed all weekend to facilitate this delivery and construction across I-5. The express lanes are closing early (at 9:00 pm) on Friday, February 26 and will remain closed all day Saturday and Sunday. They will reopen Monday, March 1, at the usual time. 

By fall 2021, you will be able to walk, roll and bike safely above I-5 using the Northgate Ped/Bike Bridge thanks to your investment through the Levy to Move Seattle. The Northgate Link Extension is expected to open this year and the Northgate Ped/Bike Bridge is a crucial piece of an important puzzle we’re putting together with regional partners to ensure walking, rolling, and biking to the Northgate Station is easier and safer.  

This weekend, our contractor will deliver one of two final bridge spans, which have been constructed off-site. They will be stored in the median between the express ramp and I-5 northbound lanes. They will be installed over I-5 in the coming months.

A 234-ft bridge span that will go across I-5 is constructed off-site. 

At the end of March, the final bridge span will be delivered. We will alert travelers of closures related to this delivery as well. 

We’ll install handrails and 10-foot tall fence to the spans prior to lifting them in place in early May. When it’s time to install the spans, we’ll move them into place and lift them by cranes. We’ll be in touch in the coming months with information about nighttime and weekend detours related to this work. 

You can expect to read more about the Northgate Ped/Bike Bridge on our blog in the coming weeks. Stay tuned!
