Ada's Village Trail Tunnel – Moore & Bruggink investigated several options to allow a safe crossing of Ada's Village Trail at the Rail America Railroad. The options included a signalized surface crossing, reconstruction of the existing railroad bridge with a wider span, or tunneling under the railroad. It was determined the tunneling option would provide the safest crossing. Since the train traffic could not be detoured or even delayed, the railroad required all construction to be complete over the four-day Thanksgiving holiday. The contractor began work following the last train on Wednesday, and completed the tunnel and placed new railroad tracks by Saturday afternoon, two days ahead of the first train which arrived on schedule on Monday morning.
