The Indiana Department of Transportation plans to install a test section of barrier wall delineators on Friday along the right side of northbound Interstate 65 in southern Johnson County. INDOT says that the northbound I-65 lane will be closed to traffic at mile marker 86.06 for approximately 30 minutes, beginning at 10 a.m., while installers affix the “A”-shaped metal delineators to concrete wall sections.

INDOT officials say the reflective delineators mounted on pre-cast concrete barrier wall sections help motorists navigate through construction zones at night. They add that existing delineators are secured to concrete walls by an adhesive. However, efforts to remove snow and ice, along with damage from passing vehicles has required a number of pieces to be replaced. INDOT’s Office of Material Management wants to see if these test-pieces, which are mechanically affixed with screws and bolts, will improve durability and service life.

If you plan on traveling north through Johnson County at around 10 a.m. on Friday, you may want to plan an alternate route.
