I-5 JBLM Vicinity Congestion Relief Project Environmental Assessment enters public comment period.
On October 4, 2016, WSDOT published an Environmental Assessment (EA) for the I-5 - JBLM Vicinity Congestion Relief Project. The EA contains the results of our studies on how this project may affect the environment. The comment period for the environmental assessment is October 17 - November 22, 2016.
- A combined environmental hearing and informational open house is scheduled from 4 to 6:30 p.m. on Monday, November 7, 2016 at the McGavick Conference Center, Clover Park Technical College, 4500 Steilacoom Boulevard SW, in Lakewood, WA, 98499.
- If you cannot attend the environmental hearing but would like to comment on the Environmental Assessment, you can submit your comments through Nov. 22 using the online comment form.
In July 2015, the Washington State Legislature included $495 Million for the I-5 Mounts Road to Thorne Lane Interchange - Corridor Improvements project, as part of the Connecting Washington transportation-revenue package. The project is in the environmental review stage.
Since September 2015, WSDOT has held two community meetings in Tillicum, and one meeting in DuPont held on May 23, 2016. Thank you to all who have attended and provided feedback during these meetings. You can view a list of meetings on the projects Public Involvement web page.
Over the past decade, populations in Thurston and Pierce counties have grown exponentially as a result of new residential neighborhoods, new businesses and growth at Joint Base Lewis-McChord. As a result, this has led to increased traffic congestion along Interstate 5.
In recent years, WSDOT, along with local city, county and JBLM officials, have refocused efforts to reduce traffic congestion and improve the existing highway operations (pdf 786 kb). Below is a list of projects that WSDOT and partnering municipalities are jointly working on to improve the flow of traffic along I-5 in Thurston and Pierce counties:
I-5 - Mounts Road to Thorne Ln I/C - Corridor Improvements
In July 2015, the Washington State Legislature included $495 million to fund the I-5 Mounts Road to Thorne Lane Interchange - Corridor Improvements project, as part of the Connecting Washington transportation revenue package. The project is funded through a 10 year period, from 2015-2025. Options advancing forward which are now undergoing environmental review are as follows:
- Add one northbound lane from Mounts Road to Thorne Lane.
- Add one southbound lane from Thorne Lane to Steilacoom-DuPont Road.
- Rebuild three interchanges using roundabouts at Thorne Lane, Berkeley Street and Steilacoom-DuPont Road
- Build a new local connector road between Gravelly Lake Drive and Thorne Lane.
- Build a bicycle/pedestrian path along the I-5 corridor.
- Build a new DuPont Gate to JBLM at the new Steilacoom-DuPont Road interchange.
Interstate 5 JBLM Vicinity Congestion Relief Study
A joint I-5 corridor planning study involving WSDOT, JBLM and local jurisdictions is evaluating the best way to improve transportation through the JBLM vicinity. The planning study identifies improvements from Center Drive to Gravelly Lake Drive.
I-5 - Mounts Rd. to Center Dr. Auxiliary Lane Extension
In spring of 2017, contractor crews working for WSDOT will extend the existing northbound Interstate 5 auxiliary lane from Center Drive to Steilacoom-DuPont Road south by 1.5 miles to Mounts Road near DuPont. This work has independent utility, meaning it provides benefits to the traveling public independent of other I-5 - Mounts Road to Thorne Lane I/C Corridor Improvements project elements.
Madigan Access Improvements
A $5.7 million grant was awarded to the city of Lakewood to improve traffic circulation from I-5 toward Madigan Army Medical Center.
I-5 - SR 510 to SR 512 Congestion Management
WSDOT will install ITS devices in Thurston and Pierce counties. The ITS devices will help WSDOT manage traffic and communicate real-time traffic conditions to the public. This project also establishes an auxiliary lane on southbound I-5 in Lakewood between Thorne Lane and Berkeley Street to accommodate the high volumes of traffic that use the exit.
I-5 - SR 510 to SR 512 ITS & Ramp Revisions
WSDOT will install ITS devices, which help WSDOT manage traffic and communicate real-time traffic conditions to the public. This project will also revise the I-5 Center Drive interchange in DuPont, allowing for continued use from JBLM.
I-5 - SR 510 to SR 512 ITS Fiber Improvements
This project is preparatory to installing intelligent transportation systems (ITS) devices, which help WSDOT manage traffic flow and communicate real-time traffic conditions to the public and media.
I-5 Nisqually Road SW/JBLM Mounts Road Gate - Signal
This project provides turn lanes and installed a new traffic signal on Old Nisqually Road at the JBLM Mounts Road Gate. These improvements allow motorist to exit JBLM from this gate.
