Four Alaska airports are getting nearly $31.2 million in infrastructure improvement grants from the Federal Aviation Administration.

More than half of the total — $18.9 million — will go to repair a taxiway and build a new taxiway at Juneau International Airport, according to a statement from the U.S. Department of Transportation.

“This significant investment in airport improvements in Alaska will fund construction and rehabilitation projects that will help maintain high levels of safety in U.S. aviation,” said U.S. Transportation Secretary Elaine L. Chao in the statement.

In addition, Kotlik Airport will get $11.4 million to expand a service road, make repairs to a taxiway and runway, and install navigational tools.

Another $500,000 will go to Sitka Rocky Gutierrez Airport for an environmental study, and Anchorage’s Merrill Field will get about $328,000 for “a study to determine alternatives for runway incursion risk reduction measures,” the statement reads.

In all, the FAA is giving $3.18 billion in grants from the Airport Improvement Program to 232 airports in 43 states, including American Samoa, the Northern Mariana Islands and Puerto Rico.
