I-5 - JBLM Area Improvements

A new project webpage is being created to provide information on the $495 Million I-5 Mounts Road to Thorne Ln I/C - Corridor Improvements project. This project was included in the Connecting Washington transportation-revenue package, which was approved by the Washington State Legislature in July 2015. The new project page will go live in the coming weeks. Thank you for your patience.

 

September 1, 2015 TILLICUM & WOODBROOK COMMUNITY MEETING

In July 2015, the Washington State Legislature funded future transportation projects to improve traffic flow on I-5 through the JBLM corridor. WSDOT proposes to rebuild the I-5 interchanges at Berkeley Street and Thorne Lane as part of those improvements. Access to and from I-5 would be modified at both locations, changing how the residents of Tillicum and Woodbrook reach the highway.  The public is invited to attend a WSDOT community meeting to hear about the proposed changes. WSDOT particularly encourages Tillicum and Woodbrook residents and businesses to attend the meeting and to share their thoughts.

  • WHEN: Tuesday, Sept. 1, 2015
  • TIME: 6 to 8 p.m. (presentation begins at 6:30 p.m.)
  • WHERE: Tillicum Community Center, 14916 Washington Ave. SW, Lakewood, WA 98498. Accessible by Pierce Transit Bus #206.


Background
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 8.4 mb). 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:

Current Projects
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 accomodate 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.

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.

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.

Completed Projects
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.

I-5 Fort Lewis/McChord Transportation Analysis - Complete September 2010
The completed study includes a list of recommended safety, congestion and transportation improvement projects for I-5 through the study area that could be built over the next 20 years as funding becomes available.
