Lemhi County Airport- Master Plan Update

The Lemhi County Airport is located in one of Idaho’s most remote communities. Due to its isolation, the airport is vital to the community for cargo, life flight, medical and business activities. Set in mountainous terrain at a relatively high altitude, the single runway configuration did not meet design standards and additional runway length was needed to support existing larger aircraft activity. The T-O planning team was able to work with the community and the FAA to justify a wider runway and runway extension. Our efforts during the planning process came to reality in 2013 when the airport completed the extension, widening and rehabilitation of Runway 17-35, improving the access and safety of the airfield.

Lemhi County Airport – Extend, Widen and Rehabilitate Runway 17-35

Through our work on the Airport Master Plan Update, T-O Engineers’ planning team was able to justify not only a runway widening but also a runway extension. As the runway pavement was nearing the end of its useful life, T-O Engineers assisted the airport with the design of a single project to extend, widen and rehabilitate the runway.

As the project would essentially shut down their airport for an extended duration, keeping the project on schedule was a priority for the airport and the community. As this would be the largest project the airport had ever undertaken, keeping the project within the $2.3 million budget was also extremely important. T-O Engineers split project into phases to minimize shutdowns of the airport and keep access to the remote mountain community. Due to delays in grant funding, the project started a month later than the anticipated start date of early June. Regardless of the start date, the project was completed on time and under the $2.3 million project budget providing the community with improved access and the airport with a safer runway.
