Construction crews should start expanding the C Concourse at Spokane International Airport in early spring.
Airport board members will award a contract for the work at their March 15 meeting. Construction could begin immediately thereafter.
The $650,000 project will more than triple seating capacity in the concourse, from 73 chairs to 241.
It also will expand bathroom and concession facilities and make the concourse accessible to people with disabilities, said Dennis Locke, aviation services manager.
In all, more than 10,700 square feet of space will be added to the narrow concourse.
Most of the addition will be built before it’s connected to the existing building, hopefully minimizing inconvenience to passengers, airport spokesman Todd Woodard said.
Horizon Air is the only airline using the “C” concourse now, but the expansion will provide enough space for additional carriers, Woodard said.
