The definition of substantial completion varies depending on the project, Manning wrote, but "In general, it means the roadway is functional and open to traffic with limited restrictions."
As of this week, all paving on the main traffic lanes along the 21-mile stretch of Section 5 is finished. All entrance and exit ramps are open. All striping and reflective markers have been placed on the main traffic lanes. All access roads have been paved and striped. There will still be some lane restrictions for work such as slope grading, fence installation and the placement of stone, but "the highway is functional and open to traffic with limited restrictions," Manning wrote.
On weekends and during major events, such as home Indiana University football games, there will be at least two lanes open to traffic in each direction. The speed limit will continue to be reduced throughout the section as crews finish work outside the main travel lanes, such as clearing drainage pipes and installing signs. This work may require some lane restrictions during the week.
