Project Title & Location
15TH ST SW TO S. 180th St. STAGE 3: HOV LANES--Auburn to Renton
|
Project Description
This project reduces congestion by adding a northbound high occupancy vehicle lane and adding ramp meters and high occupancy vehicle bypass lanes at several interchanges.
|
|
Contractor/Consultant
Project is not yet advertised or awarded.
|
|
Recent Progress
Design documentation was completed except for some minor revisions.
|
|
Design Construction Impacts
Recent advances in methods to treat and detain storm water runoff made the old design obsolete. The storm water system must be redesigned to meet the higher-level environmental requirements, which could possibly cause nearly a year delay.
|
|
Environmental Impacts / Compliance
Five-year-old permits obtained for the old design have expired. We must reapply after the storm water system is redesigned.
|
Impacts to Traffic
The project will improve the efficiency of the general purpose and HOV lanes. Construction will require lane closures at times during non-peak hours. Public outreach will be conducted.
