TULSA, Okla. — Tulsa International Airport's primary commercial runway has reopened following a six-month reconstruction project.

The $20.3 million project is the third phase of a four-phase program to completely reconstruct the nearly 10,000-foot runway. The final phase is to reconstruct the intersection of two runways at the airport and is to begin next year.

Airport officials say the total project is estimated to cost $55 million and is being largely funded by Federal Aviation Administration grants.
