Travelers at Flint's Bishop International Airport will see the results of a $16.8 million expansion.
The Flint Journal reports a dedication is Tuesday.
The construction project included a larger Transportation Security Administration area that opened in October.
The project also added 47,000 square feet of terminal space and four gates.
It doubled the width of a corridor linking two sections of the airport.
Federal funding paid for about $7 million and the airport used reserve funds to pay for the rest.
The expansion increases the airport's passenger capacity.
