State and federal officials have kicked off the construction of 3,400 miles of fiber optic cable they hope will transform eastern Kentucky's economy following the decline of the coal industry. Republican U.S. Rep. Hal Rogers and Democratic Gov. Steve Beshear were among the officials that dedicated the network Monday in Hazard. The network will cost about $324 million to build. Taxpayers will pay about $53.5 million, with the rest coming from private investors.
