Now that Indiana's Interstate 69 Section 5 project has reached its "substantial completion" mark, it's time to turn our attention to Section 6, the last and final construction leg of Indiana's I-69 Corridor Project. As many of you know, Section 6 involves the upgrading of Indiana State Road 37 from a point just south of Martinsville, Indiana, north to I-465 in Indianapolis, a distance of 26 miles. Also planned are 18 miles of new, local access, or frontage, roads.
Construction of Section 6 will begin in Martinsville. There are two construction contracts for Segment 1, which covers the Martinsville area. The initial contract, which involves the construction of new local access roads and an overpass, will be let December 12, 2018, with work expected to commence in the spring of 2019. The second, and larger, contract will be let July 10, 2019. This contract comprises the bulk of the I-69 road and interchange work throughout Martinsville and vicinity. Work under this contract will likely get underway in the fall of 2019, and will then encompass two full constructions seasons—2020 and 2021. During the 2021 construction season, SR 37 throughout Martinsville will be completely closed to all traffic, both southbound and northbound.

Courtesy INDOTOf note, the final design features several significant modifications to earlier plans. First, the Ohio Street interchange (middle map) will have Ohio Street go under I-69, whereas before it was to go over. The change was due to potential flooding issues. Remember, a little more than 10 years ago, this area of Martinsville suffered a major flood (a picture of that flood was posted in a earlier post of a few months ago). Another modification is the extension of a road from the SR 39 interchange's eastern traffic roundabout to Burton Lane (last map). Also take note that the SR 39 interchange will be completely rebuilt, and will involve shifting the overpass a little south. And, Sartor Ditch, a waterway that runs near Ohio Street (middle map), will be rerouted to run under I-69 north of the new Ohio Street interchange. The new course of Sartor Ditch can be seen as a thin blue line just east (right) of the interchange.
Construction of Section 6, Segment 1, will kick off with construction of the Grand Valley Boulevard overpass, which will connect Grand Valley Boulevard (and the nearby Wal-Mart) to South Street in Martinsville proper (middle map). The new, local access road Artesian Avenue, as well as extensions of Grand Valley Boulevard and Cramertown Loop, will be built in the same time frame. Plans are for these initial projects to complete before SR 37 is closed during the 2021 construction season. It should be noted that SR 252/Hospital Drive will always stay open through the construction work zone, even when SR 37 is closed.
A couple of earlier posts have posed questions concerning Section 6 in Martinsville and Morgan County, and I'll try to formulate and post responses in forthcoming posts. I also plan to take some "before" photos in the Martinsville area before construction gets underway. Construction of Section 6 is going to ramp up rapidly. It will be fun to watch it unfold.
