BELLEVUE, Wash. – Mark Holmes, PE, joined HNTB Corporation as construction services deputy director for the Northwest District. Holmes is based in HNTB’s Bellevue office and manages construction projects with the City of Seattle and other clients.

Throughout his career, Holmes has demonstrated exceptional skills and experience in project management for the design and construction of interchanges, arterials and local roads, utility improvements, site grading and more.

“Mark’s experience makes him an invaluable addition to our team,” said Jim Thomson, PE, HNTB Northwest district leader and senior vice president. 

“Our clients appreciate his skills and expertise as we work together to enhance transportation infrastructure within the Puget Sound region.”

Prior to joining HNTB, Holmes worked for another consulting firm where he led teams on projects including the City of Snoqualmie’s Tokul Road Roundabout/SR 202 improvements; Kitsap Transit’s Federal Transit Administration-funded North Base and North Viking Park and Ride; and the City of Sammamish’s Inglewood Hill storm water and drainage improvements.

Holmes earned a bachelor’s degree in civil engineering from the University of Washington.

HNTB, which established its Seattle office in 1961, traces its roots in the region back to 1912, when the Columbia River Interstate Bridge between Portland, Oregon, and Vancouver, Washington, opened. The bridge was designed by John Lyle Harrington, a partner in HNTB’s predecessor firm, Waddell and Harrington. HNTB has grown to employ more than 180 professionals in the region who help play a role in planning and delivering high-profile transportation infrastructure projects across the state and around the country.

HNTB’s many signature infrastructure projects in the region include the SR 99 Alaskan Way Tunnel; Mercer Corridor improvements in Seattle; Seattle-Tacoma International Airport third runway; the second Tacoma Narrows bridge; Sound Transit University Link Light Rail Extension, the Lynnwood Link Extension, West Seattle and Ballard Link Extensions and East Link Extension; Washington State Department of Transportation General Engineering Consultant Services for I-405 and SR 509; South Park Bascule Bridge Replacement in Seattle; Mount Baker Ridge Tunnel; historic work on I-5 dating back to the 1960s; and Tilikum Crossing bridge in Portland.
