The Indiana Department of Transportation (INDOT) will suspend most highway construction and maintenance activities on Friday, Aug. 30 ahead of the Labor Day holiday weekend. INDOT has a policy of limiting restrictions during highly traveled times in order to optimize mobility and public safety.INDOT and contractor workers will stop work in most construction zones and, where possible, restrictions will be removed. Some closures and restrictions will remain on projects that cannot safely reopen to traffic.Motorists traveling on Labor Day through Indianapolis via I-65 or I-70 will encounter restricted travel lanes and highway work zones near the north and south splits as contractors modify pavement markings, uncover signs and place barricades and barrier wall ahead of the midnight closure. I-465 around the south side of Indianapolis is the official detour for the downtown I-65/I-70 closure.Motorists traveling this weekend should also be alert for drivers who might be under the influence of alcohol. Recent data from the Indiana Criminal Justice Institute show alcohol-impaired driving fatalities rose nearly 13 percent in 2012. INDOT encourages all motorists to avoid drinking and driving, and to report suspicious or reckless driving behaviors to law enforcement.
