Effective Tuesday, 29 May 2012, the current driveway behind (south) the BNC will be closed and the new, temporary gravel driveway will become the only route south of the facility. It is strongly recommended that you use an alternative route. If you choose to use the gravel drive, please use caution as it is much narrower than the existing driveway and will be the primary access point for trucks delivering to the BNC dock and gas yard. A firm date for the BNC electrical shutdown has not been established, but it is likely to be mid to late summer. More information will be provided as the contractor firms up their schedule. Thank you for your understanding and cooperation during this multiyear project. John John R. Weaver Facility Manager Birck Nanotechnology Center Purdue University (765) 494-5494 jrweaver@purdue.edu
