Tower Rd is never reopening in accordance with the BAL 2010 Masterplan on the BAL website - it will disappear under RWY C lengthening, and the deliberate division of the airport into southern and northern precincts. Expect the southern side tenants to be moved to the northern side, and the southern side to become non-aviation tenancies. There are the rental returns..... and the need to win their court action. The Rwy extension is there to accomodate the likes of the E-Jets to provide an increase in RPT traffic. It's all there in the public domain, straight from the BAL master plan.
