CONTACT & LOCATIONS NEWS MARKETS SERVICES PROJECTS ABOUT CAREERS MARKETS TRANSPORTATION Highways / Roads A clear understanding of specific issues related to transportation Much of our geotechnical services work is in the study of transportation-related alignments and facilities. This work includes highways and roadways, bridges, elevated structures and tunnels. On most of our transportation projects we are also involved in conducting geotechnical studies and providing design recommendations for project elements relative to foundation design, earth retention, pavement and site drainage. Shannon & Wilson has been a major provider of engineering services for roads, bridges and transit projects throughout the United States and abroad. We have provided geotechnical studies and recommendations, seismic design, tunnel engineering, instrumentation and construction observation for many high capacity transportation projects, many that have crossed major waterways and been in seismically active regions. SERVICES INCLUDE: Geotechnical engineering for foundations, shoring and slope stability design Seismic design and retrofit Construction monitoring Construction dewatering Tunneling and tunnel construction management Analysis of geologic hazards Environmental and natural resource services HIGHWAYS/ROADS PROJECTS SR 520 Floating Bridge And Landings Project Transportation MORE Alaskan Way Viaduct Replacement Program MORE Beartooth Highway Emergency Repairs Transportation MORE Cleveland Innerbelt Transportation MORE Tacoma Narrows Bridge Transportation MORE SR 532 Corridor Improvements Transportation MORE Port Mann Bridge Transportation MORE Chuitna Coal Project MORE Parks Highway Pavement Evaluation Transportation MORE Seward Highway Rehabilitation Milepost 75-90 Transportation MORE Alaska 2018 Earthquake Response Transportation MORE Storis Drive Water Line Improvements Transportation MORE Dalton Highway Milepost 109-144 Reconstruction Transportation MORE Tanana River Bridge MORE Northern Region DOT&PF Class V Injection Well Closure MORE Multiple F-35A Projects Property Development MORE Gaffney-Airport-Richardson-Steese Interchange Transportation MORE White Point Landslide Transportation Water MORE Burnside Bridge Seismic Resiliency Study Transportation MORE I-5 Medford Viaduct Planning & Environmental Study Transportation MORE Trinity River Corral Bottom Road Bridge Transportation MORE Yuba County Landslide Emergency Repair Transportation MORE Duportail Bridge Transportation MORE Colorado DOT Geotechnical Asset Management Program Transportation MORE Glenwood Canyon Instrumentation Transportation MORE I-25 North Design-Build Transportation MORE I-225 Light Rail Design-Build Transportation MORE Red Rock Canyon Scenic Loop Drive Transportation MORE Statewide Retaining Wall Asset Management Program Transportation MORE CDOT Region 4 State Highway 14B Transportation MORE D1 Slope Stabilization Design-Build, Phase 2 Transportation MORE Floyd Hill Realignment Preliminary Design Transportation MORE Horseshoe Bend Landslide Transportation MORE I-25 Bridge At MP 50.055 Transportation MORE Long X Road Slope Failure Transportation MORE North Dakota Highway 73 Construction Transportation MORE Route 10 Jones Hole Road Transportation MORE SR-28 Shared-Use Path Transportation MORE SEE ALL PROJECTS Let's Talk About Your Project GET IN TOUCH MARKETS Transportation Water Property Development Industrial Federal SERVICES Geotechnical Engineering Contamination / Remediation Geologic Hazards Natural Resources Water Resources Design-Build Tunneling / Underground Arctic Engineering Construction Management Specialty Services ABOUT The Company People Corporate Responsibility/Scholarships CONTACT & LOCATIONS Seattle Anchorage Chicago Denver Fairbanks Jacksonville Los Angeles Madison Portland Sacramento Salt Lake City St. Louis Tri-Cities PROJECTS Explore CAREERS Working At Shannon & Wilson CONTACT & LOCATIONS NEWS CLIENT PORTAL © 2021 SHANNON & WILSON, INC.
