Twin River’s hallways were abuzz Monday and Tuesday as the district held an open house both days, giving the public a chance to roam the halls of the new school building. Hundreds of people took advantage of the opportunity to check out the building ahead of school returning this week. For most of the public the open houses were the first opportunity to get inside the new school. The district has completed phase one of the $39.9 million building project. Phase two of the project will happen throughout the next school year. The new building project is expected to be complete next summer.
