Helena Regional Airport (KHLN) to replace some of its oldest pavement

Some of the oldest pavement at Helena Regional Airport that dates back to the days of Gerald Ford’s presidency will be replaced.

While the airport has future plans for improving its main runway and an array of improvements to the terminal building, work began last week to resurface a portion of the taxiway, the strip of pavement on the north side of the runway that ferries aircraft between the runway and the terminal.

Farther to the east, the taxiway also gives the Army National Guard facility and others access to the runway.

Jeff Wadekamper, the airport’s director, said the taxiway project is estimated to cost $989,000 and completion is slated for mid-September. The work is being done by Helena Sand and Gravel and Morrison-Maierle is doing the engineering and design work.

The top 3 inches of pavement will be removed and replaced with new asphalt, he said of the section of taxiway that extends from the west end of the runway to about the middle of the terminal building.

Drains will be installed to help carry water from the edge of the runway, which will help prevent the edges from deterioration.

The oldest portion of the taxiway dates back to 1976. Construction of the taxiway came two years before the original terminal building opened.

Other portions of the taxiway date to the 1990s, Wadekamper said, so it is in good condition and won’t require the extensive work planned for the oldest portion of the taxiway.

Cracks in the taxiway’s newer section will be filled and then the surface sealed, he added.

The main runway will need to be closed for brief periods when work is ongoing but closures won’t interrupt the airport’s scheduled commercial service, Wadekamper said.

Work on the taxiway will also be done in sections to ensure other entities at the airport can continue their operations during construction, he noted.
