Upcoming Symposium

The upcoming 69th annual Highway Geology Symposium will be held in Portland Maine, September 10th through September 13th, 2018, at the Holiday Inn By The Bay.  The hotel is located 5 miles from the Portland International Jetport with complimentary shuttle service. The Holiday Inn By the Bay is steps away from the historic downtown Old Port waterfront along the picturesque shore of Casco Bay.  The Old Port features working fishing wharves and converted warehouses with restaurants and shops and is known for its cobblestone streets, 19th century brick buildings and fishing piers.  Come and experience the natural beauty and unique culture of Portland, Maine.


Online conference registration is now open and available through the button on the right.  Also available is the paper form for download.  Early full conference registration rates are $350 through July 16, 2018.   Please also refer to the early announcement and call for papers for additional information.


The Holiday Inn By the Bay no longer has rooms available for the entire symposium. To make reservations for individual nights, you can contact the hotel at 1-800-345-5050 or 1-207-775-2311 or check with other nearby hotels.


Sponsors and Exhibitors!

We invite you to participate in the 69th annual Highway Geology Symposium.

The symposium program is designed to encourage connecting and networking while fostering closer cooperation and better understanding between geologists and civil engineers in the highway industry.  The event draws engineering geologists and geotechnical engineers from state and federal agencies as well as academia, colleges and universities, consulting firms, and construction industries.   A sponsorship will offer you an opportunity to make face-to-face connections with influential staff and key industry leadership from around the country. The exposure will reinforce your brand awareness and maximize visibility within the geotechnical community, through a positive association and a much anticipated event. A variety of sponsorship opportunities exist to allow industry partners to get involved.

Online registration for sponsors and exhibitors along with the printable brochure and registration form are available on the buttons to the right.

Transportation Research Board Workshop


There will be a half-day Transportation Research Board workshop before the Symposium on Monday, September 10th. This is an annual event for TRB at the Highway Geology Symposium (HGS). The 2018 TRB Workshop Title is: “Geotechnical Asset Management: Implementation of Programs and Advances in Technology”.  This workshop will explore the implementation of geotechnical asset management (GAM) programs for rock and soil slopes along with other geotechnical assets. Presentations will demonstrate the state of the practice as GAM programs complete research and development phases and move into active use at state and federal agencies.  The session will also include presentations on the active development of remote sensing and other data collection and interpretation methods in support of GAM programs.  The session will include four 30 minute invited presentations followed by a 30 to 45 minute open discussion on the state of GAM practice in the transportation industry. This workshop is sponsored by the Joint Section Subcommittee on Geotechnical Asset Management (AFP00(1)), Standing Committee on Geotechnical Site Characterization (AFP20), and Standing Committee on Engineering Geology (AFP10)


New information will be posted as it becomes available. We hope to see you in Maine!


Calling Young Authors

The Highway Geology Symposium has existed for nearly 70 years and over the years has had much participation by what might be considered “Young Authors”. This participation by our younger professionals has been fabulous and is a true benefit to the Symposium and the Mission of HGS. In recent years, HGS has taken participation of Young Authors to another level by sponsoring a competition with both financial, registration and award recognition. This is an annual and perpetual award with up to three awards presented. We are very excited about this continued opportunity for participation by Young Authors and we encourage you to submit your paper and to present your work at the Symposium. If you know a Young Author that should join this competition, encourage them to check out the guidelines and submit their abstract. HGS is all about sharing our geologic technical experiences and we look forward to hearing about and learning from your experience. So please see the links for guidelines and participation requirements as well as award details.

We occasionally send out email announcements on upcoming symposiums. If you would like to receive these, subscribe to our mailing list here:
