In addition to roadway improvements, the I-69 Finish Line project includes the construction or preservation of over 30 acres of wetlands, 350 acres of trees, and over 14,000 linear feet of stream improvements. Chain link fencing will direct wildlife to a safe crossing underneath the interstate at Little Indian Creek in Martinsville.
- The new I-69 will be four through lanes, two in each direction, south of Smith Valley Road.
- The highway will be widened to six travel lanes, three in each direction, from Smith Valley Road to Southport Road.
- When completed, there will be eight lanes, four in each direction, on I-69 from Southport Road to I-465 and on the southwest leg of I-465 between I-70 and I-65.
