Construction of the $16.8m expansion at Bishop International Airport in Michigan, US, will begin in the next few months, according to airport officials.
The work will involve doubling the size of the passenger corridor and adding four new gates and 4,366m² of terminal space.
After the expansion the facility will be able to serve two million passengers a year by 2012.
Bishop International Airport Authority Board cleared the way for contractors to start preparing bids for the expansion work.
The airport undertook a $3.2m expansion project last year, while another $1.4m was spent on replacing two jet bridges and building a new one, according to mlive.com.
