Spokane International Airport in the US has begun a multi-year programme to upgrade runways, aprons and taxiways to enhance flight-handling capacity.
The runway will be extended to 2,000ft, so airlines can operate fully loaded aircraft.
The increase will also allow airlines to land longer flights with full fuel tanks.
The second phase of the programme will see aprons rebuilt and expanded adjacent to the terminals at a cost of a $15.5m.
As part of the renovation, new apron concrete will be poured around concourse B and the south-west portion of concourse A.
The runway extension programme secured $30m from the federal economic stimulus bill, according to spokesman.com.
US-based firms Acme Concrete Paving served as the general contractor while Colvico will oversee the electrical work for the project.
