Bullock Contracting, based in Boulder, also supplies trucks to move everything. In total, Wadekamper said about 50 trucks will be needed to complete the project in eight days.
To give a better idea of ââthe scale of the project, Wadekamper said 6.8 acres of paint will be used on the finished track.

Funding for the $ 10.8 million project comes entirely from the federal government. The lion’s share is covered by the Federal Aviation Administration’s Airport Improvement Program, which is funded by taxes levied on all airline tickets, air cargo, and aviation fuel. Typically, with FAA grants, a small portion of the total project cost must be paid by the airport as a local counterpart.
