Work being done in Bethel to get the future police station site ready for construction has turned up some unexpected challenges.  The remains of an old barn that burnt down in the late 70s was found buried on the parcel off Whittlesey Drive.  The barn is on the part of the land where the firing range is planned and the area had to be back filled after removal.  Crews also found old cement columns had been illegally dumped on the site and buried.  They were from when the middle school was built nearly 30 years ago.  The removal of the debris cost about $175,000 and comes from the project's contingency account.
