INDIANAPOLIS – Contractors are ahead of schedule on the South Split construction project. The Indiana Department of Transportation says favorable weather and the ability of crews to work around the clock are primary factors.
According to INDOT, Milestone Contractors finished removing the pavement Saturday night for the half mile of road being reconstructed. Crews used milling machines to grind up asphalt and falling weights to break up original concrete pavement.
Contractors are putting in new drainage, treating roadbed soil and laying six inches of stone base before adding three inches of asphalt base. The work has already been finished for the new I-70 eastbound ramp to I-65 southbound.
For the project’s first two weeks, ramp traffic is using a temporary configuration with a 30 mph speed limit. The final pavement layer will be steel-reinforced concrete, which INDOT said is thin durable under heavy traffic.
An analysis from INDOT and Purdue University’s Joint Transportation Research Program shows traffic is primarily using the I-465 detour, causing some additional congestion as expected during peak times on the I-465 south leg and I-65 northbound approaching I-465 south. The analysis showed there has been little effect on I-65 and I-70 traffic patterns within the I-465 loop.
