COMING SOON! I-405/SR-73 Express Lanes Concrete Pour

COMING SOON! New Portion of the Westminster Boulevard Bridge Opening
Crews began the second phase of construction of the Westminster bridge in 2021. When the new portion of the bridge opens this summer, it will have new vehicle lanes and sidewalks. Additionally, crews are constructing new traffic signals for the Westminster/Springdale Street and the Westminster/Willow Lane intersections.
The I-405 Improvement Project is excited to deliver an improved bridge to your community!
Please note that the northbound I-405 off-ramp to Willow will be permanently closed as part of the project improvements, and crews will continue constructing traffic signals, striping new bike lanes and conducting drainage work in the coming months.
To open the new portion of the bridge, the community should expect a full bridge closure for one night so crews can restripe lanes.
