NASHVILLE (AP) - Gov. Bill Haslam and Transportation Commissioner John Schroer have released a 3-year transportation plan for the state.

The $1.5 billion plan includes improvements to the interstate system, such as truck climbing lanes and interchange reconstruction.

It also funds projects along strategic corridors such as U.S. 27 in Roane, Morgan and Scott counties; U.S. 79 in Carroll and Gibson counties; and U.S. 64 in Middle and West Tennessee.

Other priorities include projects aimed at stimulating economic development, such as the reconstruction of the interchange at I-40 and SR 222 to facilitate access to the West Tennessee Megasite in Haywood and Fayette Counties.

The plan also provides funding for local transit agencies and planning organizations, shortline railways and bridges, and airport improvements.
