BOZEMAN, Mont. -

Martel Construction is set to head up the Haynes Pavilion expansion. Folks with Gallatin County made the announcement to County Commissioners Tuesday.

They tell us the next step in the process is a preconstruction contract. That should be firmed up within the next couple of weeks. From there, they'll ask Martel for the guaranteed maximum price for the project.

Gallatin County Procurement Officer Nick Borzak tells us, depending on weather, construction should begin in May and last for three months.
