The Lone Tree School District is now accepting bids for an upcoming construction project. The district would like to add a 1,200 square foot entrance vestibule to the south side of the high school gymnasium as it exists now. Initial estimates for the project were just over half a million dollars. The new entrance would improve handicap access, safety and security.  A public hearing on the plans, specifications and contract will take place as part of the school board’s scheduled  meeting on Wednesday, November 13th.
