Changes to the design of Indiana's Interstate 69 extension from Bloomington to Martinsville will save at least $100 million in taxpayer dollars and require fewer homes, businesses and wildlife areas to be razed, according to this article. The 21-mile project, which has been given federal approval, will now cost about $394 million compared with the original estimate of between $500 million and $546 million. Work includes new access roads and widening and ­upgrading the four-lane highway.
