The latest round of work at the Columbia Regional Airport is complete.
In August, workers started demolishing and rebuilding the pavement around the intersection between the main runway and crosswind runway.
It cost almost $5 million, but 90% of that was covered by federal grants.
The city still wants to improve the crosswind runway, with construction starting by 2017.
Rangeline Road is also getting moved and rebuilt next year to make room for those future plans.
That will cost $1.5 million, paid for mostly by the FAA.
