Reconstruction of Hillsborough-North Superior Court is on schedule and under budget, according to project managers. With the passing of each day, the old courthouse on Chestnut Street in Manchester, NH, which was gutted early this year and had extensive asbestos removed by July, looks less and less like a giant, steel shell. The project, scheduled to be finished in July 2011, is being funded through $17 million the state appropriated in 2009 to cover everything from asbestos abatement to exterior landscaping.
