Great Falls International Airport in the US has almost completed the second phase of its $8m taxiway renovation project.
The four-phase project involves rehabilitation of the 10,500ft taxiway-A, which runs alongside the airport's main runway.
Project work includes major repairs, renovation of lighting and altering the area's drainage system.
The airport's deputy director of operations and maintenance, Rod Hall, said that centre-line lighting is being installed at the airport to suit low-visibility operations.
Rehabilitation became necessary as the taxiway and pavement have deteriorated through use.
The last two phases of the project are expected to begin in 2010.
