Atkinson Creates Highway Tunnel Crews Continue Work On Vital Washington Project Atkinson Construction is making steady progress on the new Veterans Drive tunnel as part of the SR 509 Completion Project. This portion of work is part of the overall Puget Sound Gateway Program, which aims to build critical connection points in Washington’s highway and freight network. In August, crews began shifting northbound I-5 traffic to the left over a recently completed section of the Veterans Drive tunnel near SR 516 in SeaTac so work could continue. The tunnel runs east-west under I-5 and will provide more direct access to manufacturing industries in the Kent Valley, allowing freight to bypass the busy SR 516 interchange. The tunnel is made of steel arches and will carry two lanes of traffic in each direction. “Finishing SR 509 will improve freight mobility to and from our ports and provide an important north-south alternative to I-5 between Seattle and south King County,” said Gateway Program Administrator John White. “Atkinson Construction has a long history of successfully delivering complex highway projects for WSDOT. We’re looking forward to working with them to complete the design and construction of the final 2 miles of SR 509.” The SR 509 Completion Project in King County is part of the Puget Sound Gateway Program, which also includes the SR 167 Completion Project in Pierce County. Together, these projects complete two of the Puget Sound region’s most critical freight corridors and improve access to I-5, the ports of Tacoma and Seattle and Seattle-Tacoma International Airport. The SR 509 Completion Project builds a new four-lane expressway between I-5 and SR 509's cur-

rent end near Sea-Tac Airport, builds new I-5 ramps, improves I-5 interchanges in south King County and constructs new bridges. When complete, the project will create an important north-south alternative to the congested I-5 corridor between Seattle and south King County. A total of $2.68 billion funds both the SR 509 Completion Project in King County and the SR 167 Completion Project in Pierce County. see TUNNEL page 10
